[alsa-devel] Help with SoC alsa.conf
by Paul Kavan 21 Jun '07

21 Jun '07

I am trying to determine an appropriate conf file for my AT91SAM9260ek running linux-2.6.22-rc1 and the following alsa drivers: <6>Advanced Linux Sound Architecture Driver Version 1.0.14rc4 (Wed May 09 09:51:39 2007 UTC). <6>ASoC version 0.13.0 <4>AT91SAM9260EK W6811 Driver <1> <6>w6811: W6811 PCM SoC Audio 0.1 <6>asoc: W6811 <-> at91-ssc0 mapping ok <6>grh_ek_w6811: W6811 PCM in Slave Mode <6>ALSA device list: <6> #0: GRH_EK_W6811 (W6811) I have installed alsa-lib-1.0.14a and alsa-utils-1.0.14 on the at91sam9260. The default conf file produces sound using speaker-test and aplay, but will not record using arecord. Frank Mandarino has been kind enough to lend me a barebones conf that worked for him: pcm.!default { type hw card 0 } pcm.hw { type hw card 0 device 0 subdevice 0 } ctl.!default { type hw card 0 } ctl.hw { type hw card 0 } but produces the following for me: /usr/share/alsa $ aplay -l **** List of PLAYBACK Hardware Devices **** ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0 ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0 aplay: device_list:213: control open (0): Invalid argument ALSA is *very* new to me and I am unsure how to interpret any of this. I am using a dumb W6811 pcm codec. I am fairly confident the machine/codec driver is working as expected, so I need to determine what I can do to get alsa to play nice with it as well. When I use the default alsa.conf produced from making alsa-libs, I get the following: /usr/share/alsa $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: GRHEKW6811 [GRH_EK_W6811], device 0: W6811 W6811-PCM-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 record and playing do not seem to work. When I try: /usr/share/alsa $ arecord -d5 test.wav Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Aborted by signal Interrupt... It does not stop at 5 seconds....I have to interrupt it manually. Furthermore, it does not appear to record anything as when I: /usr/share/alsa $ aplay test.wav Playing WAVE ' test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono The speaker pops once, but no audio. Finally, when I use speaker-test, I get some weird results. Doing: /usr/share/alsa $ speaker-test -r8000 -c1 -f1000 -tsine -l1 speaker-test 1.0.14 Playback device is default Stream parameters are 8000Hz, S16_LE, 1 channels Sine wave rate is 1000.0000Hz Rate set to 8000Hz (requested 8000Hz) Buffer size range from 64 to 32768 Period size range from 32 to 8192 Using max buffer size 32768 Periods = 4 was set period_size = 8192 was set buffer_size = 32768 0 - Front Left Time per period = 5.086305 Gives me a wave composed of both the 1k sine and likely a 2k sine. If I go much below 1k, I get a periodic wave, but it looks more like a heart beat. My codec expects u-law, so that may be the problem with speaker-test. However, the fact the aplay and arecord are not working give me pause. I would be greatly appreciative of any insights, pointers, etc. If there is more information that would be helpful, please ask. Thanks. Paul -- *************************************** Paul David Kavan Project Engineer GRH Electronics, Inc. 402-734-4900 pkavan(a)gmail.com ***************************************

Hi Clemens, > You could compare <http://manuals.opensound.com/devlists/Linux.html> > with ALSA's sound card matrix, but the latter tends to be out of date. > Yeah, that thing is oooooold. Hopefully the new wiki on't be too bad. > > With the recent open sourcing of OSS, it would be nice to port code > > to ALSA for devices that are only currently covered by OSS. > > AFAICS all devices supported by the open-source OSS are also supported > by ALSA. > Ah, looks can be deceiving. Although both systems have 'geode' support, it seems that the OSS driver supports the CS5530 VSA2 and the SC1200. Also, there's an open bug for the Neomagic 256 driver, which may have a solution hiding away in OSS somewhere (someone with the hardware is hopefully going to help me look into that). There's a couple of things right off the bat and I don't know ALSA very well at all compared to most of you. And yeah, I know this stuff isn't in great demand, but it'd be nice if people weren't able to say that OSS can do XYZ and ALSA can't. Ash -- Get a Free E-mail Account at Mail.com!

[alsa-devel] OSS/4Front
by Ash Willis 21 Jun '07

21 Jun '07

Hi, Does anyone know if there's any kind of list showing a comparison of hardware support between ALSA and OSS/4Front? With the recent open sourcing of OSS, it would be nice to port code to ALSA for devices that are only currently covered by OSS. There has to be at least a few devices that we can grab support for, right? It may at least provide us with insight into a few bugfixes. Ash -- Get a Free E-mail Account at Mail.com!

[alsa-devel] No time for cs4624
by chris＠idlelion.net 21 Jun '07

21 Jun '07

I really wanted to work on the cs4624 suspend resume bug (#305), but there is no time, especially given the lack of technical information. I'm wondering if I were to lend or give a laptop that exhibits the problem to one of you alsa developers, if that would be useful and provide some impetus to fix the bug, or if it would just be a big pain? Opinions? Chris

[alsa-devel] Output levels on SBLive! 5.1 on ALSA vs WIndows
by ChernYue Kwok 20 Jun '07

20 Jun '07

Hello, I am using an SBLive! 5.1 sound card (emu10k1 chipset) with 6 channel output. Due to the nature of my work, I need to be able to play sound through all 6 channels at the same output level to an amplifier. Using Linux and the emu10k1 ALSA driver, I measured output voltage levels on an oscilloscope while playing a sine wave on all 6 channels, and I got three different output voltage amplitudes for the front, rear and center/subwoofer channels. Repeating the same test with the same card on WIndows using the Creative SBLive drivers from their website, I am able to get the same output voltage amplitude on all 6 channels. For both tests, all output levels in the relevant mixers were set to their maximum levels. I would like to know if this output normalizing 'feature' of the SBLive Windows driver can be found in the emu10k1 ALSA driver, or in any other ALSA driver. Failing that, is there any other solution to set output levels in the driver, or am I doomed to twiddle in alsamixer to get the output levels that I want? Thanks in advance.

[alsa-devel] Using aplay and arecord on an ARM
by Paul Kavan 20 Jun '07

20 Jun '07

Liam: I have managed to get the alsa-libs and aplay, arecord, and speaker-test on my board, but I am unsure how to get them to play. I have tried making the device nodes and am using a simple alsa.conf, but still no joy. I am sure there is something simple I am missing. Trying to find some documentation on this. I am assuming there is some disconnect between the interface and my conf file. I have my alsa.conf file in /usr/share/alsa/ and it is: pcm.!default { type hw card 0 } pcm.hw { type hw card 0 device 0 subdevice 0 } ctl.!default { type hw card 0 } ctl.hw { type hw card 0 } ctl.w6811 { type hw card 0 } pcm.w6811 { type hw card 0 device 0 subdevice 0 } ctl.!default = ctl.w6811 pcm.!default = pcm.w6811 ctl.hw { @args[ CARD ] @args.CARD { type string default "0" } type hw card $CARD } pcm.hw { @args[ CARD DEV SUBDEV ] @args.CARD { type string default "0" } @args.DEV { type integer default 0 } @args.SUBDEV { type integer default 0 } type hw card $CARD device $DEV subdevice $SUBDEV } I have some /proc/ entries: /proc/asound $ ls GRHEKW6811 cards pcm version card0 devices timers /proc/asound $ cat cards 0 [GRHEKW6811 ]: W6811 - GRH_EK_W6811 GRH_EK_W6811 (W6811) /proc/asound $ cat devices 0: [ 0] : control 16: [ 0- 0]: digital audio playback 24: [ 0- 0]: digital audio capture 33: : timer /proc/asound $ cat pcm 00-00: W6811 W6811-PCM-0 : : playback 1 : capture 1 /proc/asound $ cat timers G0: system timer : 10000.000us (10000000 ticks) P0-0-0: PCM playback 0-0-0 : SLAVE P0-0-1: PCM capture 0-0-1 : SLAVE /proc/asound $ cat version Advanced Linux Sound Architecture Driver Version 1.0.14rc4 (Wed May 09 09:51:39.

[alsa-devel] ALSA always writes _whole_ periods, right?
by Joachim Förster 20 Jun '07

20 Jun '07

Hi ALSA devs, I have a quick question regarding the filling of the usual ring buffer in RAM (used by sound controllers via DMA), just to be really sure: Is it true, that ALSA always writes (via mmap'ing) _whole_ periods? I took snd-dummy and modified it to use "ack()" method and tried to confirm, if the above is true _without_ memory mapping (classical read/write). It seem's to be true, ALSA is "filling up" the last (not always complete) period - e.g. if the played wav file is not a multiple of periodsize in length. But well, with mmap, I cannot see the copying action (done by ALSA library, right?) ... so, thus my question ;-) . Thanks, Joachim

[alsa-devel] Surround problems with cs46xx
by Vasilis Manwlopoulos 20 Jun '07

20 Jun '07

Hi, Sorry for bothering the list again, but I have major problems with the surround 5.1 sound. I have manually compiled/installed th latest alsa-1.0.14 drivers but nothing improved. I am using Ubuntu 7.04 and my soundcard is the Hercules Fortissimo III. This is, as far as I know by reading on Internet, supported by the module snd-cs46xx in ALSA. I have enabled the surround sound by creating the following .asoundrc file. pcm.!default { type plug slave.pcm "surround51" slave.channels 6 route_policy duplicate } The problem is that sound pauses whenever I try to do something "heavy" such as opening a new firefox window or generally another app. Also, there are delays and echo between the front and the rear speakers from time to time. I think that the problem is that, this alsa setup(meaning surround5.1 and the specific soundcard) places a heavy load on the cpu. There are 99% cpu usage times when the only thing active is a player playing a "normal bitrate" mp3. When I delete the .asoundrc file and I switch to default stereo sound using only the 2 front speakers the problems disappear. Can anyone suggest anything about this? Thanks in Advance V.Manolopoulos

[alsa-devel] question about bluez using alsa and patches
by Walt Shekrota 19 Jun '07

19 Jun '07

I was told that when using the btsco(bluez) and/or plugs bluetooth headset software a patch is always required. In the Gentoo community and perhaps everywhere it is suggested to use alsa compiled into your kernel. As I go to new kernels frequently these folks (sco headset) seem to have no such forward support ie they have not worked on the patches yet for the newer kernels. Am I wrong or at some point in time should this app not be weaned from using patches? Is it the fact they use sco that they have to patch? Is there not an alsa library they can program to instead. I guess I don't understand the overall design so I can't see why this goes on forever. I'm somewhat apprehensive about trusting others to continually modify my kernel. Am I out in left field here? Can anyone explain why they must choose this path? Thanks very much. -Walt

[alsa-devel] Difference between substream->dma_buffer and substream->runtime->dma_buffer_p?
by Timur Tabi 19 Jun '07

19 Jun '07

The snd_pcm_substream structure has a snd_dma_buffer structure. snd_dma_buffer looks like this: struct snd_dma_buffer { struct snd_dma_device dev; /* device type */ unsigned char *area; /* virtual pointer */ dma_addr_t addr; /* physical address */ size_t bytes; /* buffer size in bytes */ void *private_data; /* private for allocator; don't touch */ }; snd_pcm_substream also has a snd_pcm_runtime structure, which looks like this: struct snd_pcm_runtime { ... /* -- DMA -- */ unsigned char *dma_area; /* DMA area */ dma_addr_t dma_addr; /* physical bus address (not accessible from main CPU) */ size_t dma_bytes; /* size of DMA area */ struct snd_dma_buffer *dma_buffer_p; /* allocated buffer */ Why the redundancy? Not only does snd_pcm_runtime have dma_area, dma_addr, and dma_bytes, but it also has a pointer to a dns_dma_buffer structure, which also has this information! So given a snd_pcm_substream structure, you can obtain the physical address of the DMA buffer three ways: substream->dma_buffer.addr substream->runtime->dma_addr substream->runtime->dma_buffer_p->addr When will these three variable contain different values? If the answer is never, then why do they all exist? -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Changing the sample rate/channels of an already opened PCM stream
by Ed Schouten 19 Jun '07

19 Jun '07

Hello, I am the author of the command line music player Herrie (http://herrie.info/). For a long time folks have asked me to add support for OSS to Herrie, so this morning I decided to install Linux on a spare disk of mine (Ubuntu 7.04, FWIW) to hack on ALSA support for Herrie. After (a real lot of) hours of reading code, reading the Doxygen stuff, etc. I now have a functional ALSA output module for Herrie. It was quite hard to get it working, so I guess I owe myself a beer! ;-) Anyway, there still is one disadvantage to my module; each time I detect that a new track is going to be started that needs a different amount of channels or sample rate, I reopen the ALSA device, something that is just impossible. The reason why it's impossible: Herrie has a nifty chroot() functionality that allows users to trap the application in a certain directory. I have been trying to get the device to reset so I can change the sample rate, but for some reason, it just gets ignored. Can someone explain me how it's possible to reset the sample rate after preparing the handle? For your information, here's a link to the latest version of the source code of my ALSA module: http://g-rave.nl/gitweb?p=herrie;a=blob;f=herrie/src/audio_output_alsa.c Yours, -- Ed Schouten <ed(a)fxq.nl> WWW: http://g-rave.nl/

[alsa-devel] Writing an AT91SAM9260-EK Dumb Codec Driver
by Paul Kavan 18 Jun '07

18 Jun '07

Hello all: I am working on a driver for a dumb codec to work with the SSC as a PCM on the AT91SAM9260. I have, with the gracious help of Frank Mandarino, have the glue code written without too many problems. However, I need some guidance on getting a few things configured correctly for my codec and then getting it to compile and load correctly. For configuration, I am using the Winbond W6811. For this, I am going to use a 256kHz BCLK and an 8kHz frame. Each sample consists of 8-bit u-law PCM, MSB first. When I execute a read from the codec to the processor, I need to make the reads on the falling edge of the BCLK at each sync pulse. When executing a write from the processor to the codec I need to write on the rising edge at each sync pulse. I think I the timing correct in my driver with: cmr_div = 187; /* PCM_CLK = ~96MHz/(2*187) = 256kHz */ period = 15; /* PCM_SYNC = PCM_CLK/(2*(15+1)) = 8000Hz */ However, I am not sure how to get the following correct for my needs: #define W6811_FORMATS (SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_LE) Now to making the driver once the code is done. I am relatively new to writing linux drivers. In the 6 or so that I have written, I usually cross-compile them as modules and then insmod them. I have tried that here and am getting a strange warning that I am unsure of. I have a pretty simple Makefile and when I execute it, I get: make ARCH=arm CROSS_COMPILE=arm-linux- make -C ~/Linux_Builds/linux-2.6.21.5M=/home/grhuser/Door_Access_System/Remotes/Driver/sound modules make[1]: Entering directory `/home/grhuser/Linux_Builds/linux- 2.6.21.5' CC [M] /home/grhuser/Door_Access_System/Remotes/Driver/sound/grh_ek_w6811.o Building modules, stage 2.

For this attempt to build the driver, I have a separate folder than contains: at91-ssc.h and at91-pcm.h. If there is a more correct way to do this and be able to debug it, please let me know. I have attached copies of my driver. I would appreciate any and all feedback and assistance on getting this running.

[alsa-devel] Query regarding pcm->private_data
by Pharaoh . 18 Jun '07

18 Jun '07

Hi I am reading 'Wring an alsa driver'. It says following about the private_data: You can allocate a record for the substream and store it in runtime->private_data. Usually, this is done in the open callback. Don't mix this with pcm->private_data. The pcm->private_data usually points the chip instance assigned statically at the creation of PCM, while the runtime->private_data points a dynamic data created at the PCM open callback. What does static and dynamic mean here? Apologies for this question if it sounds very novice, since my understanding is it doesn't mean static and dynamic in the usual way like stack and heap etc. Why I am being so paranoid about this has reason: In my ALSA driver I am assigning pcm->private_data = mychip, but it is NULL in the snd_pcm_attach_substream() function. I have checked my code many times and I tried with another driver which was working when tested using ALSA utils. Currently I am testing using the OSS emulation i.e. simply cat /dev/audio.

[alsa-devel] Alsa mixer interface limitations?
by Ctirad Fertr 17 Jun '07

17 Jun '07

Hello! I'm currently in phase of adding support for higher sample rates into e-mu 1212m/1820m driver. These cards have a lot of physical inputs and outputs and also a bunch of internal buses used for capture, playback and internal routing between physical inputs and outputs. Both physical I/O and internal buses are shown in alsamixer, so one can set routing easily. It's a lot of switches, anyway. The card has three modes. The standard (or "single speed") mode is the only mode currently supported in emu10k driver. It is capable of 44.1/48kHz sample rate only. If we need higher sample rates, we have to switch the card into either "double speed" (for 88.2/96kHz) or "quadruple speed" (for 176.4/192kHz) mode. The problem is that the number of inputs, outputs and especially internal buses significantly changes at higher speed modes. The reason is that internal buses are 44.1/48kHz only and thus we must use two (or four) of them per channel. Also some physical I/O ports disappear at double and quadruple speeds (e.g. ADAT has 4 channles at 96k and 2 at 192k, S/PDIF is completely disabled at 192k). The question is how to deal with that in alsamixer? IMHO the best way would be to change the number of switches in alsamixer on the fly. Unfortunatelly, I'm afraid it's impossible. Another way would be to make a particular swiches inactive, though I don't know if it is a good idea and it wold require a lot of code anyway. Any ideas? Please help! Ctirad

[alsa-devel] Got microphone working with SigmaTel STAC 9221 A1 on a Dell XPS M1210
by Eran Guendelman 17 Jun '07

17 Jun '07

I installed SuSE 10.2 on my new XPS M1210 laptop and found that the microphone was not working (headphones and internal speakers worked fine). I eventually got it working, and wanted to write an email describing how I did this. The two main important steps (which I will describe in more detail below) were: - Changing the default pin configurations ref922x_pin_configs in patch_sigmatel.c to values that were based on the windows driver's INI file but with one important tweak. - Running the driver using the "model=ref" parameter so that the above modified pin configurations are used. Note that it could be that my solution is overkill and there's actually a way to get this working with the unmodified alsa drivers... But I did not find any such solutions (e.g. I've tried setting "model=ref", "model=3stack", "model=5stack", but none of those fixed the microphone). In general, it seems that the solutions proposed on the internet to getting the SigmaTel codec working are very dependent on the exact type of system you've got... So this will likely only work for a Dell XPS M1210. Here is some more system info: "lspci -v" gives this as my audio card: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Subsystem: Dell Unknown device 01d7 Flags: bus master, fast devsel, latency 0, IRQ 233 Memory at efffc000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Unknown type IRQ 0 Capabilities: [100] Virtual Channel Capabilities: [130] Unknown (5) My card uses the snd_hda_intel module, and the codec type (given by "cat /proc/asound/card0/codec#0") gives this information at the top: Codec: SigmaTel STAC9221 A1 Address: 0 Vendor Id: 0x83847680 Subsystem Id: 0x102801d7 Revision Id: 0x103601 So here's what I did (taking many days and many wrong steps before arriving at this solution): - I have a dual-boot system and installed the official DELL drivers for the sound card in Windows XP. My goal was to find which INI file corresponded to my installed sound card, so I did the following: - Using Windows device manager, I looked at the properties for the SigmaTel codec driver and found that one of the property items had a string that included the substring VEN_8384&DEV_7680&SUBSYS_102801D7 - The self-extracting DELL driver extracted files into c:\dell\drivers\r122161, and in the wdm subdirectory I searched for the above string and found that the files 92xxM.INI, Sthda.ini, and sthda64.ini all contained the above string and also had the suffix =92xxM8-2.ini appended to it. This led me to deduce that the relevant file was 92xxm8-2.ini - This is an excerpt from 92xxm8-2.ini: [HKR\Settings\pin\0A] CfgDflt = dword: 0x0221121E AltCfg = hex: 20,12,11,02 Action = hex: 80,00,87,00,81,0D [HKR\Settings\pin\0B] CfgDflt = dword: 0x408103FF [HKR\Settings\pin\0C] CfgDflt = dword: 0x0281123E AltCfg = hex: 22,12,11,02,30,12,A1,02 Bias = hex: FF,04,02 Action: hex: 0A, 0C [HKR\Settings\pin\0D] CfgDflt = dword: 0x90100310 [HKR\Settings\pin\0E] CfgDflt = dword: 0x408003F1 [HKR\Settings\pin\0F] CfgDflt = dword: 0x0221122F AltCfg = hex: 21,12,11,02 Action = hex: 80,00,87,00,81,0D [HKR\Settings\pin\10] CfgDflt = dword: 0x03451340 [HKR\Settings\pin\11] CfgDflt = dword: 0x40C003F2 [HKR\Settings\pin\15] CfgDflt = dword: 0x50A003F3 [HKR\Settings\pin\1B] CfgDflt = dword: 0x405003F4 - This will be useful later... Now back to linux. - I downloaded latest alsa-driver package (version 1.0.14). - I edited alsa-kernel/pci/hda/patch_sigmatel.c, and replaced the contents of the ref922x_pin_configs array with the default pin configurations found in the INI file above WITH ONE IMPORTANT TWEAK. Specifically, this is my new array: static unsigned int ref922x_pin_configs[10] = { 0x0221121E, 0x408103FF, 0x02A1123E, 0x90100310, 0x408003F1, 0x0221122F, 0x03451340, 0x40C003F2, 0x50A003F3, 0x405003F4 }; - If you compare these numbers to the CfgDflt values from the Windows INI file above, you'll see that they match except that for the third value, instead of 0x281123E I use 0x2A1123E Here's why: I figured out that pin complex 0x0c was my microphone jack (the right-most of the three jacks in the front of my laptop). The 0x281123E configuration indicates a "Line In at Ext Front" jack... Indeed, this jack can serve as a line in or mic in or even I believe as output to rear speakers. But designating it as Line In by default seems to confuse the patch_sigmatel.c routines that set up the codec... They assume it's just a line in jack and do not mark it as potential microphone input. Changing the 8 to an A in the value designates it as "Mic at Ext Front", so the codec recognizes it as the microphone input for the card. What ends up happening is that as a microphone input, the Pin-ctls for the pin gets assigned to 0x24, whereas when it just thinks it's a Line In the Pin-ctls gets set to 0x20. Both designate an input, but the 4 in 0x24 seems to also give it a Voltage Reference Signal which I guess is important for microphone inputs. (I don't fully understand most of this stuff... I've just been reading up about the HD Audio specs over the last few days). - Build and install drivers using "./configure --with-cards=hda-intel --with-sequencer=yes; make; make install" - Make sure the snd_hda_intel gets loaded with model=ref option. You need to specify the ref model so that the pin configurations set up above are used. Of course, the right way to do this would be to make a whole new model, but I didn't bother doing that in my quick hack. Anyway, in SuSE 10.2 you can set the model through YaST, or you can manually edit /etc/modprobe.d/sound and make sure model=ref is listed as one of the options in the "options snd-hda-intel . . ." line - Reset sound drivers. (Best to just reset computer, but on SuSE 10.2 it usually works if I do "/etc/init.d/alsasound reset") - And that's basically it... In the mixer (e.g. alsamixer) it's important to make sure the Capture channel has "CAPTUR" on and that it's at a high value, and that the Mux is at its max too. It does not allow me to change "Input Source", but that's fine because the above essentially hard codes it to be Front Mic which is what I wanted. I've attached the contents of /proc/asound/card0/codec#0 in its good (mic working) state. The final path is 0x0c (mic) -> 0x12 (audio selector, stereo amp-out; Mux in the mixer) -> 0x17 (audio selector, stereo amp-in; Capture in the mixer) -> 0x06 (audio input) After searching on the internet, reading about HD Audio, and poking around the driver code, I do have a number of lingering questions I would be happy to have answered: - Why does patch_sigmatel.c "fix" mux capture levels to 2? The Mux (0x12) ends up in the path from the mic in jack to the audio in, so is it supposed to act as a Mic Boost or something? - I noticed my headphone jacks (0x0a, 0x0f) have Pin-ctls set at 0xc0 which is OUT HP (i.e. uses a low impedance amplifier for headphone output). Would it damage my sound card or speakers if I connected these jacks to powered speakers or to an audio receiver (i.e. more traditionally connected to a Line Out)? - Does the snd_hda_intel driver currently (or will it eventually) support dynamic switching so I can switch from the Mic In to Line In or to Rear Speakers Out, etc, just like in the Windows driver? - Some solutions on the internet talked about creating an .asoundrc file to get the codec working... I don't understand what that file is for and whether I need to tweak it at all... But since I have a working solution without the file I guess I'm fine? Thanks, Eran. P.S.

[alsa-devel] Software mixing according to priority of streams
by Nobin Mathew 15 Jun '07

15 Jun '07

Hi, Is there any sound mixer which does mixing according to priority of streams, i.e. i will have streams with different priority like audio stream , bluettoth sco stream, gps navigation sound stream etc. Since my hardware will not support hardware mixing i will have to do this mixing in software. If bluetooth sco stream is opened while audio stream is playing then the application (sound server) should stop the playback of audio stream and should start playback of bletooth sco stream. priority order is bluettoth sco > gps navigation sound > audio Can dmix and Jack server the purpose.

[alsa-devel] [RFC][ASoC] New device/driver arch
by Liam Girdwood 15 Jun '07

15 Jun '07

I'd like to gather some feedback on some changes I've been making to ASoC recently. The changes were made to fit in better with the PPC device tree and to help with easier porting to new platforms. They were also introduced to make dealing with device probe errors (e.g. I2C probe failure) a little easier. The largest change is the introduction of an ASoC bus device. All component drivers (that is, codec, codec DAI, CPU DAI, and DMA PCM drivers) register with this bus. This should simplify device registration and hopefully better fit in with the PPC model. A component driver now typically consists of the standard driver ops and a set of ASoC/ALSA ops to configure audio. The new soc.h shows this here :- http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-as… Example component drivers are here :- I2S http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-as… DMA http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-as… WM8753 Codec http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-as… Another major change is that there is no more snd_dai_link (structure that connected codec <--> CPU). This has been replaced by an ASoC PCM device that describes each PCM device in the machine. This new ASoC PCM device has it's own driver and registers with the bus (like the others). This allows an ASoC PCM driver to be defined like :- static struct snd_soc_device_driver hifi_pcm_drv = { .type = SND_SOC_BUS_TYPE_PCM, .driver = { .name = "mainstone-hifi-pcm", .owner = THIS_MODULE, .probe = hifi_pcm_probe, .remove = hifi_pcm_remove, }, .components = { .cpu_dai = pxa2xx_i2s, .codec = wm8753_codec, .codec_dai = wm8753_hifi_dai, .platform = pxa2xx_pcm, }, }; This now shows each component within the driver structure. The snd_soc_machine driver has changed and can now contain numerous ASoC PCM devices. It is now a platform driver. Example machine driver for Mainstone with WM8753 is here :- http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-as… The machine driver now also does the I2C/SPI probing (instead of the codec) and also does any codec IO (to better support multiple controllers). Fwiw, I've not tested any of this code atm. I plan to start this tomorrow on pxa2xx and i.MX31 and would like to get some feedback before porting remaining platforms and codecs over. Liam

[alsa-devel] Trouble understanding ALSA's DMA buffers
by Timur Tabi 12 Jun '07

12 Jun '07

I'm writing an ALSA SOC driver for an I2S-based device, and I'm having a really hard time understanding how ALSA uses the DMA buffers. And yes, I've read the documentation and studied some sample source code. I used to write audio drivers for a living, but that was many years ago, and it wasn't for Linux. Perhaps the concepts in my head are outdated, but I just don't see enough explanation as to how DMA buffers are supposed to work. Back then, audio drivers used "ping pong" DMA buffers. A single DMA buffer is allocated, and the audio hardware is programmed to read from that buffer in a loop. That is, it would automatically restart reading from the beginning of the buffer without any reprogramming. The hardware would also be programmed to issue an interrupt when it got to the end of the buffer, and when it got to the half-way point. To start playback, you first filled the whole buffer with audio data, and then told the hardware to start playing. After the hardware got to the half-way point, it would issue an interrupt. You would then tell the OS you need more data, and you'd get it. You then copy that data into the first half of the buffer *while* the hardware was playing the second half. Later, the hardware would interrupt you when it got to the end of the buffer. You'd then copy more data to the 2nd half while the hardware is playing the first half. And so - hardware plays one half while you copy data to the other half. Hence, "ping pong". So how do I implement this in ALSA? The "Writing an ALSA Driver" document doesn't even contain the words "ping" or "pong". -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Realtek 268

I have tried the current (from about 6 hours ago) drivers+lib from the HG repository. My card is now labelled as an ALC 268, and shows me what appears to be a correct number of options in the mixer. Unfortunately, I still get no sound. I've compiled the driver with --debug=full, and the lib with the debug.

[alsa-devel] alsa on Atmel at91
by Michel Benoit 12 Jun '07

12 Jun '07

Hello I am trying to run alsa on an ARM based target AT91SAM9260 based board. The cpu is connected over i2s (atmel's ssc) to a PCM1725 chip. I modifed the AT73C213 driver available in the latest experimental patches from www.at91.com to behave correctly for the PCM1725 chip. Basically all I have done is remove the spi communication with the AT73C213 that regulates the sound output volume. The PCM chip has no such volume control and I use the i2s interface setup as is to send sample data. I cross compile alsa lib and run the program test/pcm_min which generates as expected random noise on the speaker output. However when I try to run test/pcm I get a divide by zero floating point exception because the library returns a period_size of 0. This despite the fact that the period time is set to 100000 and buffer time is set to 500000. I enabled some debug info in the library and I see the following data dumped to the console. ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 48000 PERIOD_TIME: (20354 20355) PERIOD_SIZE: 977 PERIOD_BYTES: 3908 PERIODS: (4 5) BUFFER_TIME: (81479 81480) BUFFER_SIZE: 3911 BUFFER_BYTES: 15644 TICK_TIME: 10000 How is it possible that the following code from test/pcm.c err = snd_pcm_hw_params_set_period_time_near(handle, params, &period_time, &dir); if (err < 0) { printf("Unable to set period time %i for playback: %s\n", period_time, snd_strerror(err)); return err; } err = snd_pcm_hw_params_get_period_size(params, &size, &dir); if (err < 0) { printf("Unable to get period size for playback: %s\n", snd_strerror(err)); return err; } returns a period_size of 0 when the debug output shows that the period_size has been calculated to be 977? Can it be that the driver has not initialised the alsa structures properly (the driver file is attached to this email)? Have I mucked something up by removing the spi comm. with the at73c213? Could this be due to a problem in the cross compilation of alsa-lib? I use the following configure command line: CC=arm-linux-gcc ./configure \ --host=arm-linux\ --prefix=$HOME/bsp/rootfs/buildroot/build_arm/root/usr\ --with-softfloat (note: I have also tried it without --with-softfloat) I have tried digging through the alsa lib code but it is not very clear to me where the returned value for period_size comes from. I appreciate any pointers, hints or tips that can help me to solve and/or understand this problem. Thanks in advance! Michel

[alsa-devel] Source of timing for MIDI and/or audio synchronization
by Mark Rivera 12 Jun '07

12 Jun '07

Hello (new to list), and thank you for the work you have been doing. As an end-user of the ALSA project's development, I am very grateful for being able to use softwares which provide audio functionality to Linux. I have been reading up on the docs and list archives, but I still have an open question for which I hope you can lead me to an answer. I designed and built a MIDI sequencer based around a Microchip PIC18 MCU, and used the built-in hardware timers and interrupt levels to drive the 'scheduler' for initiating MIDI output (EUSART) routines. In this same vein, I would like to write a software sequencer with as 'tight' timing as possible. So, in a similar concept for Linux - from where does the timing of audio and MIDI events come from? It occurred to me that it would be nice to have a loadable kernel module (LKM) to which userland programs could subscribe for receiving 'soft interrupts' based on some timer (cpu ticks?) so that various software could all reference the same notion of the "current time" - a sort of "master clock" with start/stop/continue as well. Does ALSA provide this functionality? Can someone point me in the right direction for learning more about this? Many thanks. Mark

[alsa-devel] [PATCH] snd-usb-caiaq: Fix compatibility with kernels < 2.6.19
by Sergey Vlasov 12 Jun '07

12 Jun '07

Kernels before 2.6.19 used a different signature for the urb->complete callback (an additional "struct pt_regs *regs" parameter was present), therefore snd-usb-caiaq needs some compatibility patches in alsa-driver, like snd-usb-audio. Signed-off-by: Sergey Vlasov <vsu(a)altlinux.ru> --- The snd_usb_caiaq_midi_output_done() part is somewhat hackish - the problem is that snd_usb_caiaq_midi_output_done() is declared in caiaq-midi.h, and the alsa-driver build system does not support patching of *.h files. The rest is basically copied from usbaudio.patch. Without the patch compiling for 2.6.18 produces warnings: .../usb/caiaq/caiaq-device.c: In function 'init_card': .../usb/caiaq/caiaq-device.c:316: warning: passing argument 6 of 'usb_fill_bulk_urb' from incompatible pointer type .../usb/caiaq/caiaq-device.c:321: warning: passing argument 6 of 'usb_fill_bulk_urb' from incompatible pointer type .../usb/caiaq/caiaq-audio.c: In function 'alloc_urbs': .../usb/caiaq/caiaq-audio.c:583: warning: assignment from incompatible pointer type --- alsa-driver-1.0.14/usb/caiaq/Makefile.alt-caiaq-api 2007-06-11 16:29:28 +0400 +++ alsa-driver-1.0.14/usb/caiaq/Makefile 2007-06-11 19:50:39 +0400 @@ -5,6 +5,13 @@ endif include $(SND_TOPDIR)/toplevel.config include $(SND_TOPDIR)/Makefile.conf +clean-files := caiaq-audio.c caiaq-device.c + include $(SND_TOPDIR)/alsa-kernel/usb/caiaq/Makefile +EXTRA_CFLAGS += -I$(SND_TOPDIR)/alsa-kernel/usb/caiaq + include $(SND_TOPDIR)/Rules.make + +caiaq-audio.c: caiaq-audio.patch $(SND_TOPDIR)/alsa-kernel/usb/caiaq/caiaq-audio.c +caiaq-device.c: caiaq-device.patch $(SND_TOPDIR)/alsa-kernel/usb/caiaq/caiaq-device.c --- alsa-driver-1.0.14/usb/caiaq/caiaq-audio.patch.alt-caiaq-api 2007-06-11 19:18:40 +0400 +++ alsa-driver-1.0.14/usb/caiaq/caiaq-audio.patch 2007-06-11 19:18:17 +0400 @@ -0,0 +1,26 @@ +--- ../../alsa-kernel/usb/caiaq/caiaq-audio.c 2007-06-11 16:29:28 +0400 ++++ caiaq-audio.c 2007-06-11 19:17:38 +0400 +@@ -464,7 +464,11 @@ static void fill_out_urb(struct snd_usb_ + check_for_elapsed_periods(dev, dev->sub_playback); + } + ++#if !defined(OLD_USB) && !defined(CONFIG_SND_NEW_IRQ_HANDLER) ++static void read_completed(struct urb *urb, struct pt_regs *regs) ++#else + static void read_completed(struct urb *urb) ++#endif + { + struct snd_usb_caiaq_cb_info *info = urb->context; + struct snd_usb_caiaqdev *dev; +@@ -518,7 +522,11 @@ static void read_completed(struct urb *u + usb_submit_urb(urb, GFP_ATOMIC); + } + ++#if !defined(OLD_USB) && !defined(CONFIG_SND_NEW_IRQ_HANDLER) ++static void write_completed(struct urb *urb, struct pt_regs *regs) ++#else + static void write_completed(struct urb *urb) ++#endif + { + struct snd_usb_caiaq_cb_info *info = urb->context; + struct snd_usb_caiaqdev *dev = info->dev; --- alsa-driver-1.0.14/usb/caiaq/caiaq-device.patch.alt-caiaq-api 2007-06-11 19:55:17 +0400 +++ alsa-driver-1.0.14/usb/caiaq/caiaq-device.patch 2007-06-11 19:54:49 +0400 @@ -0,0 +1,31 @@ +--- ../../alsa-kernel/usb/caiaq/caiaq-device.c 2007-06-11 16:29:28 +0400 ++++ caiaq-device.c 2007-06-11 19:54:46 +0400 +@@ -100,7 +100,11 @@ static struct usb_device_id snd_usb_id_t + { /* terminator */ } + }; + ++#if !defined(OLD_USB) && !defined(CONFIG_SND_NEW_IRQ_HANDLER) ++static void usb_ep1_command_reply_dispatch (struct urb* urb, struct pt_regs *regs) ++#else + static void usb_ep1_command_reply_dispatch (struct urb* urb) ++#endif + { + int ret; + struct snd_usb_caiaqdev *dev = urb->context; +@@ -295,6 +299,16 @@ static struct snd_card* create_card(stru + return card; + } + ++#if !defined(OLD_USB) && !defined(CONFIG_SND_NEW_IRQ_HANDLER) ++static void snd_usb_caiaq_midi_output_done_wrapper(struct urb* urb, ++ struct pt_regs *regs) ++{ ++ snd_usb_caiaq_midi_output_done(urb); ++} ++#undef snd_usb_caiaq_midi_output_done ++#define snd_usb_caiaq_midi_output_done snd_usb_caiaq_midi_output_done_wrapper ++#endif ++ + static int init_card(struct snd_usb_caiaqdev *dev) + { + char *c;

[alsa-devel] Shutdown() vector in ALSA
by Nobin Mathew 12 Jun '07

12 Jun '07

why no ALSA driver has shutdown() vector implemented? Is this vector needed to ensure the proper shutdown of the system? What all needs to be taken care if i want to implement shutdown(), except hardware shutdown. struct snd_shutdown_f_ops { struct file_operations f_ops; struct snd_shutdown_f_ops *next; }; what this operations means? defined in sound/core/init.c Is there any need to call these functions? snd_power_change_state(card, SNDRV_CTL_POWER_D3hot); for (i = 0; i < chip->pcm_devs; i++) snd_pcm_suspend_all(chip->pcm[i]);

Re: [alsa-devel] Alsa 1.0.13 (and others) does not work on ALC880
by Andrew Callan 12 Jun '07

12 Jun '07

I have been without sound using Fedora Core ever since the 2.6.16 or 2.6.17 kernel update (2.6.16 crashed during initialization, so I could not tell whether sound worked or not). It had worked well through the 2.6.15 Fedora kernels. I finally sat down tonight to work the problem as hard as I could and happened upon Eric and Tobin's timely exchange. First, simply adding probe_mask=1 to the snd-hda-intel options worked for me as well; I did not end up having to specify a specific model. Second, I too was seeing a LONG hang when trying to do: cat /proc/asound/card0/codec#0 but now with the probe_mask=1, I do not see this. If it helps, the alsa-info.sh output for my system is at http://pastebin.ca/496293 If it makes any difference, I'm not sure which model I had specified on the modprobe line at the time I captured this output. One thing I do notice is that after adding probe_mask=1, aplay -l does not show the Si3054 Modem which shows up in the alsa-info output. Thanks for the help you gave in the thread with Eric. Andrew

[alsa-devel] Patch - Revo7.1 PCM Playback Switch
by dustin＠seznam.cz 11 Jun '07

11 Jun '07

Hello Takashi, I have attached a patch to support mute for front channels of M-Audio Revolution 7.1 (the DAC AK4381 features a mute bit). Signed-off-by: Pavel Hofman <dustin at seznam.cz> Please could I ask you for your opinion on the following issue (so far no response): I am working together with Ctirad on supporting more capture channels in E-MU1212. So far we have managed to increase the number of channels from the default of 8 to 16 (A_FXWC2 = 0xffffffff, added new snd_emu10k1_audigy_dsp_convert_32_to_2x16 calls in emufx.c). There is still a number of issues to solve but the 16 channel capture already works fine. I would like to get your opinion on the form of adding this support to the module. The options are either hard-coding the 16 capture channels into the code, assuming that users would prefer as many channels as possible and do the routing in jack, or introducing a module parameter emu1010-capture-channels (range e.g. 1 to 16 - untested yet) and leaving the default number at the existing 8. Furthermore, the PCMs other than efx seem to be of no use for the EMU-1x1x models, probably fairly confusing for new users. Would you find it OK, if they were removed for this specific card (if (emu->card_capabilities->emu1010)), keeping only the playback and capture PCM id 2? Thanks a lot for your suggestions. Based on them, I will prepare the patch (with comments on what we found out about the card - it is a pitty that the driver has almost no big-picture comments on the supported cards' specifics, making new developers spend a number of long nights going through the nontrivial code and guessing). Best regards, Pavel.

[alsa-devel] probing state of high definition audio card in windows / SigmaTel STAC9221 microphone problems
by Eran Guendelman 09 Jun '07

09 Jun '07

Hi, I am struggling to get the (external) microphone working on a SigmaTel STAC9221 A1 device on my Dell XPS M1210 laptop. I saw other emails indicating that this was still problematic, and the latest drivers from alsa 1.0.14 did not seem to fix the problem. So now that I've started reading and trying to understand the basics behind the hda codec in an effort to fix this problem, I was wondering if it was possible for me to boot into windows (I've got a dual-boot setup), get into a state where the microphone is working, and somehow probe the codec's state at that time (all of the pin configurations, etc.)... then theoretically, if I reproduce that configuration on the linux side, it should work (right?). So the question is, does anyone have a ready-made utility for Windows to do this probe of the high definition audio codec? I could probably try writing one myself, but thought I'd check if it already exists. Thanks. Please send responses by email too (not subscribed).

[alsa-devel] Sound Devices USBPre
by Brian Phelps 08 Jun '07

08 Jun '07

Hey guys, I contacted Sound Devices at sounddevices.com about writing a Linux driver (I was going to head the project but would take any help I can get) for the USBPre, a 2ch-in 2ch-out USB preamp with highquality balanced XLR Mic inputs. They said that they would love to have a Linux Driver and will provide specs for me, I am still waiting on the info though. I have not asked if I can view their firmware sourcecode yet, and if it requires an NDA, I will have to work around that. What advice do you have for writing a driver for alsa? I have written some small kernel drivers for embedded Linux devices, a few audio programs in C, and I come from a DSP background, but I am not sure exactly where to start, besides the specs and firmware. Thanks for your help -Brian Phelps

[alsa-devel] Callback trouble
by Juan Manuel Lopez Baio 08 Jun '07

08 Jun '07

Hello. I'm having some problems with the asynchronous usage of ALSA API, and I'm not sure if this usage is correct. What I have done so far is the following: I have an class that encapsulates the ALSA API, working in a multithreaded environment. I use alsa to capture audio and want to do so in an asynchronous and non-blocing way, so I defined a static method in my class that functions as callback, which receives a pointer to the instance of my class and calls on a member function, like this: void alsaDevice::myCallback(snd_async_handler_t *handler) //STATIC { alsaDevice *dev = (alsaDevice*)snd_async_handler_get_callback_private(handler); dev->triggerCondition(); } void alsaDevice::triggerCondition() { LogError(0,"Trigger en placa %d device %d",cn,dn); m_condMutex.lock(); m_noDataCondition.trigger(); m_condMutex.unlock(); } To init ALSA, I do this: int mode = SND_PCM_ASYNC | SND_PCM_NONBLOCK; if ((err=snd_pcm_open(&pcm_cap_handle, pcm_name.str().c_str(), SND_PCM_STREAM_CAPTURE, mode) < 0)) { LogError(0,"Opening ALSA PCM device %s: %s",pcm_name.str().c_str(),snd_strerror(err)); pcm_cap_handle=NULL; return false; } then set all the pertinent parameters, and finally if((asyncaddresult=snd_async_add_pcm_handler(&ahandler,pcm_cap_handle,alsaDevice::myCallback,this))<0) { LogError(0,"No se pudo registrar la callback; PCM Error: %i",asyncaddresult); } if ((asyncaddresult=snd_pcm_start(pcm_cap_handle))<0) LogError(0,"No se pudo start pcm; PCM Error: %i",asyncaddresult); Afterwards, the first time that a call to snd_pcm_readn returns EAGAIN I call wait() on a condition object with a 100 ms timeout, which is triggered by the callback, as seen before. The problem is that the callback never seems to get called (so shows the log), so I'm not really sure if the previous steps were right. Any light you can shed on this would be much appreciated. Thanks! juan

[alsa-devel] [ASoC]one Small Suggestion
by Nobin Mathew 08 Jun '07

08 Jun '07

Liam, Thank you for your support, my work is almost complete now, driver is working perfectly now. I have one suggestion, I modified the wm9713.c codec driver in probe function , so that if(socdev->machine->dai_link->cpu_dai->private_data) codec->ac97->bus->private_data = socdev->machine->dai_link->cpu_dai->private_data; Here i am assigning the controller private data. so that my following ac97 read and write to access codec registers become good. static void aaci_ac97_write(struct snd_ac97 *ac97, unsigned short reg, unsigned short val) { struct platform_controller *controller = ac97->bus->private_data; struct aaci *aaci = (struct aaci *)controller->bus_controller; static unsigned short aaci_ac97_read(struct snd_ac97 *ac97, unsigned short reg) { struct platform_controller *controller = ac97->bus->private_data; struct aaci *aaci = (struct aaci *)controller->bus_controller; u32 v; Is there a way to accomodate this in existing ASoC design? Or a better way to do this?

[alsa-devel] Testing/forcing XRUN
by Eliot Blennerhassett 08 Jun '07

08 Jun '07

Hi, I want to test my driver behaviour when an xrun happens. I have tried using aplay/arecord, and suspending (ctrl-Z) them while playing/recording but this doesn't have the desired effect. (I don't see my driver code detecting an xrun). Instead I see a trigger-stop command to the driver. The apps do report an overrun when they are restarted though. Can anyone answer these: 1) Is this a valid way to simulate an xrun due to application not keeping up? 1.1) If not, what is? Do I have to write an app that deliberately starves the streams? 2) Where is the xrun being detected if my driver doesnt see it? Where does the trigger-stop command come from when I suspend the app? thanks Eliot Blennerhassett AudioScience Inc.

[alsa-devel] Audio driver for omap 24xx.
by Pharaoh . 07 Jun '07

07 Jun '07

Hi I am referring the EAC driver for omap 24xx which is used by n800 board. The EAC 24xx driver doesn't look complete since it has only hardware init sequences and very basic ALSA related functionalities i.e. register the sound card etc. Is omap 24xx eac driver still in intermediate stage?Or it is complete but not yet integrated in to omap git tree? In later case, where can I find the complete eac driver? Also, omap 24xx driver doesn't seem to follow the framework/structure of other omap alsa drivers in sound/arm/omap/ , any particular reason? Please enlighten. I know this might be little off topic here, but there are only two places where I can ask this question, so I am trying both. -pharaoh.

[alsa-devel] Surround sound problem with CS46xx
by Vasilis Manwlopoulos 06 Jun '07

06 Jun '07

Hi to everybody, I am kind of new in linux and to alsa and I am facing a problem with the setup for 5.1 surround sound with my sound card Hercules Fortissimo III, recognized having the chip cs46xx. I have managed to enable surround sound by creating a .asounrc file with the followings pcm.!default { type plug slave.pcm "surround51" slave.channels 6 route_policy duplicate } The problem is that I am facing weird cpu load spikes (sometimes isn't just spikes, but just 99% usage for a long time!) even when just playing a normal mp3 file at 128Kbps. This is happening when playing with various players (totem,rhythbox,vlc). Also the sound has cracklings or there is a delay between the front and the rear speakers. i have send this email to alsa-users too, but since there wasn't anyone to propose a workaround I was adviced to also send it to alsa-devel. I am using the distro ubuntu 7.04 with the default alsa libraries version 1.0.13ubuntu5. So, if anyone has any idea plz give me a hint, cause I am stuck with it about two weeks now, without having any clue to proceed with!!! PS. If any other information or command output is necessary to help me, tell me so.

[alsa-devel] [ASoC]Changing the order of trigger in soc_pcm_trigger
by Nobin Mathew 06 Jun '07

06 Jun '07

Liam, I have one suggestion. Can we use this if (rtd->codec_dai->ops.trigger) { ret = rtd->codec_dai->ops.trigger(substream, cmd); if (ret < 0) return ret; } if (rtd->cpu_dai->ops.trigger) { ret = rtd->cpu_dai->ops.trigger(substream, cmd); if (ret < 0) return ret; } if (platform->pcm_ops->trigger) { ret = platform->pcm_ops->trigger(substream, cmd); if (ret < 0) return ret; } Instead of if (rtd->codec_dai->ops.trigger) { ret = rtd->codec_dai->ops.trigger(substream, cmd); if (ret < 0) return ret; } if (platform->pcm_ops->trigger) { ret = platform->pcm_ops->trigger(substream, cmd); if (ret < 0) return ret; } if (rtd->cpu_dai->ops.trigger) { ret = rtd->cpu_dai->ops.trigger(substream, cmd); if (ret < 0) return ret; } That means trigger the Cpu before pcm. Because most of the controllers needs to be initialized and triggered before external DMA is triggered. Correct me if i am going wrong. This was causing so many problems in my hardware. Nobin Mathew

[alsa-devel] Realtek 268
by Steven Zakulec 06 Jun '07

06 Jun '07

Hello ALSA developers, I have one of the Intel HDA cards that is not supported currently: Realtek 268. It was previously mentioned in May (http://mailman.alsa-project.org/pipermail/alsa-devel/2007-May/000828.html). The post seemed to imply it was not a terribly difficult task to add support for the card, but was very vague on details. If it is in fact just a matter of copying an existing preset and changing the values, I would probably try to do it myself. If it is any more difficult than that, I'd like to formally ask the developers if they could add any support for the card. The lspci and /proc/asound/codec info is identical to that in the posting I mentioned. If you need anymore information, I would be happy to provide it. Thank you!

[alsa-devel] Connecting two USB-Soundcard to JACK
by Carsten Beth 06 Jun '07

06 Jun '07

Hello! We want to connect two USB soundcards to one multichannel device at the alsa layer and to use that virtual device with JACK. But we don't find a way to do so. The USB soundcard is self-made. It woks as a high speed USB device with sample rates of up to 96 KHz, has four capture and two playback cannels. The clocks of two cards can be synchronized at hardware level. Using one card by its own works perfectly both, at the alsa and at the JACK level, also as a duplex device. All is done with alsalib 1.0.13, jackd 0.101.1 and qjackctl 0.2.21. Now I'm trying to build a virtual device with 8 capture and 4 playback channels at the alsa level. But, as it can be read at several locations, this only works for capture only or playback. It has been reported, that duplex operation is possible after patching pcm_multi.c. I have applyed the patch, but this has not changed anything. Now I want to ask you for support, to get the device running. I made some experiments with different configurations of alsa/jackd and had some strange results. You can read about the results and used the asoundrc below. Questions, that I can't answer are - Why do I see just the channels of one card when using the multi plugin in try 2), 5) and 7)? - Why is the processor load so high with playback only in try 2) and 3) but not in duplex operation? - Why are there lots non-adible xruns with playback only in try 2) and 3)? 1) playback only with p_multi ALSA: mmap-based access is not possible for the playback stream of this audio interface 2) playback only with p_multi_plug Playback of just the 1st cards two channel. Lot of processor load: Both cores of the Core Duo 2GHz system are at about 90% load. Lot of XRUNs: 08:01:35.514 XRUN callback (48501 skipped). 08:01:37.517 XRUN callback (80633 skipped). 08:01:39.519 XRUN callback (70612 skipped). but XRUNS can't be heard. Sometimes jackd terminates after a while: ALSA: could not complete playback of 256 frames: error = -32 cycle execution failure, exiting DRIVER NT: could not run driver cycle jack main caught signal 12 [...] zombified - calling shutdown handler [...] 08:01:40.926 Post-shutdown script terminated with exit status=256. 3) playback only with p_multi_route Number of channels as expected (4 channels, two from each card). Lot of processor load, like 2) Lot of non-adible XRUNS, like 2). Sometimes jackd terminates after a while with the same message as in 2). 4) capture only with c_multi ALSA: mmap-based access is not possible for the capture stream of this audio interface 5) capture only with c_multi_plug Captures just two channel from the 1st card Low processor load (near 0%) No XRUNS. 6) capture only with c_multi_route Number of channels as expected (8 channels, four from each card). Low load and no XRUNS, like 5) 7) duplex with p_multi_plug and c_multi_plug Playback and capture works just for the 1st card (two playback and 4 capture channels). Low processor load, like 2) Lot of XRUNs, but less the 2) (and now the XRUNS can be heard). Here is a snip: **** alsa_pcm: xrun of at least 0.010 msecs 11:34:00.013 XRUN callback (9 skipped). **** alsa_pcm: xrun of at least 0.014 msecs 11:34:02.037 XRUN callback (11 skipped). **** alsa_pcm: xrun of at least 0.018 msecs **** alsa_pcm: xrun of at least 0.016 msecs 11:34:04.069 XRUN callback (11 skipped). **** alsa_pcm: xrun of at least 0.016 msecs 11:34:06.099 XRUN callback (11 skipped). **** alsa_pcm: xrun of at least 0.018 msecs **** alsa_pcm: xrun of at least 0.013 msecs 11:34:08.116 XRUN callback (12 skipped). Sometimes jackd terminates after a while with the same message as in 2). 8) duplex with p_multi_route and c_multi_route Exactly the same as in 7) expect for the number of channels. Now all channels are available (four playback and four capture channels) Here the used asoundrc: ##################################### # 1st USB card ##################################### pcm.usb0 { type hw card 1 } ctl.usb0 { type hw card 1 } ##################################### # 2nd USB card ##################################### pcm.usb1 { type hw card 2 } ctl.usb1 { type hw card 2 } pcm.p_multi { type multi; slaves.a.pcm "usb0"; slaves.a.channels 2; slaves.b.pcm "usb1"; slaves.b.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave b; bindings.2.channel 0; bindings.3.slave b; bindings.3.channel 1; } ctl.p_multi { type hw; card 1; } pcm.c_multi { type multi; slaves.a.pcm "usb0"; slaves.a.channels 4; slaves.b.pcm "usb1"; slaves.b.channels 4; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave a; bindings.2.channel 2; bindings.3.slave a; bindings.3.channel 3; bindings.4.slave b; bindings.4.channel 0; bindings.5.slave b; bindings.5.channel 1; bindings.6.slave b; bindings.6.channel 2; bindings.7.slave b; bindings.7.channel 3; } ctl.c_multi { type hw; card 1; } pcm.p_multi_plug { type plug; slave.pcm "p_multi"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.p_multi_plug { type hw; card 1; } pcm.c_multi_plug { type plug; slave.pcm "c_multi"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; ttable.4.4 1; ttable.5.5 1; ttable.6.6 1; ttable.7.7 1; } ctl.c_multi_plug { type hw; card 1; } pcm.p_multi_route { type route; slave.pcm "p_multi"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.p_multi_route { type hw; card 1; } pcm.c_multi_route { type route; slave.pcm "c_multi"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; ttable.4.4 1; ttable.5.5 1; ttable.6.6 1; ttable.7.7 1; } ctl.c_multi_route { type hw; card 1; } Thank you Carsten Beth -- Dipl.-Inform.

Re: [alsa-devel] Power management state flow in ALSA
by Nobin Mathew 06 Jun '07

06 Jun '07

Liam, In soc_resume() we should do this snd_power_change_state(codec->card, SNDRV_CTL_POWER_D0); instead of snd_power_change_state(codec->card, SNDRV_CTL_POWER_D3hot); Because snd_pcm_resume in pcm_native.c expects the card to be in SNDRV_CTL_POWER_D0 state. Other ioctl will wait forever. static int snd_pcm_resume(struct snd_pcm_substream *substream) { struct snd_card *card = substream->pcm->card; int res; snd_power_lock(card); if ((res = snd_power_wait(card, SNDRV_CTL_POWER_D0)) >= 0) res = snd_pcm_action_lock_irq(&snd_pcm_action_resume, substream, 0); snd_power_unlock(card); return res; } One more thing why we are using snd_power_change_state(codec->card, SNDRV_CTL_POWER_D3cold); every other driver is doing snd_power_change_state(card, SNDRV_CTL_POWER_D3hot); SNDRV_CTL_POWER_D3cold is true for deep sleep where power to the controller is switched off . In sleep, only clock to the controller is switched off.

[alsa-devel] Problem restarting alsa: can't set buffer size
by Juan Manuel Lopez Baio 06 Jun '07

06 Jun '07

Hello. I'm developing an application that records input from ALSA and process it. To do so I user the API starting with snd_pcm_open and follow with the parameters settings and so on, and once the app is done and exits, it closes with snd_pcm_hw_params_free and snd_pcm_close. The problem is that afterwards, if I restart the application, I can't set up ALSA, becausea continuous calls to snd_pcm_hw_params_set_buffer_size always fail (I start with a buffer size of 8192 and keep dividing it by 2). I finally have to restart the system in order to get it to work again. I'm on a Mandriva box with gcc 4.1.2 ¿Any thoughts on this? Thanks in advance! juan

Hello; I am working with an CMEDIA 8738-MC6 and i am trying to gain control of the second DAC by way of softvolume. but i seem to not be succeeding because my application cant find my 'Rear' control, am i doing this correctly? the original /usr/share/alsa/cards/CMI8738-MC6.conf CMI8738-MC6.pcm.rear.0 { @args [ CARD ] @args.CARD { type string } type hw card $CARD device 1 } i have modified it to look thusly: notice that the type is now softvol and the original hardware description is encapsulated in slave.pcm # 2nd DAC CMI8738-MC6.pcm.rear.0 { @args [ CARD ] @args.CARD { type string } type softvol slave.pcm { type hw card $CARD device 1 } control { name "Rear Playback Volume" card $CARD } } Shouldnt i now be able to see 'Rear Playback Volume' in the output of amixer controls ?? as it stands right now, i can not. what am i doing incorrectly? tnx! johnu

[alsa-devel] Alsa-OSS Duplex bug (revisited)
by Alan Horstmann 05 Jun '07

05 Jun '07

About a year ago I posted an explaination of the cause of non-functioning with Alsa-OSS in duplex, together with a workaround patch. After some discussion the thread ended. However since then there has been a steady trickle of downloads of the patches from my host (it can also be found elsewhere) and some reports of great success,eg http://audacityteam.org/forum/thread/1388 (2nd page especially) In attempting to tidy up some loose ends, I hope you can bear with me revisiting this and making the case for it's acceptance. I am aware the Alsa-OSS is not of much interest to developers, and it might be said 'use native Alsa'; however that is not possible or desirable in all applications, and anyway, why provide an OSS emulation that cannot be made to work properly? To summarise the problem first: OSS provides a single SNDCTL_DSP_CHANNELS ioctl; where a device is duplex the number of capture and playback channels cannot be set separately. With original OSS this was not a problem AFAIK because separate devices are created for capture and playback, ie they are not used duplex. However Alsa-OSS in most cases creates a single combined device, which only operates correctly when an equal number of capture and playback channels are used. The Workaround: The workaround I proposed and now use constantly is like a secret trapdoor. Where the existing interface is adequate (ie captue channels == playback channels, or non-duplex) nothing changes, and SNDCTL_DSP_CHANNELS is set with a number between 0 and 128. It is fully compatible with apps that don't know of the secret door -the front door is used! However, if an app needs to set capture channels != playback channels, in duplex, at present the stream will malfunction every time. But with this patch applied, if the app knows the workaround, then it can simply set SNDCTL_DSP_CHANNELS as playback + 256*capture channels, and this will be interpreted correctly in the patched Alsa-OSS and the stream functions correctly. As I say, there is therefore no loss of compatibility in either direction. Providing the app only uses the special formula when necessary rather than always, it is only providing a way to fix something that is broken. It would seem to me of value to add the patch to Alsa so that the workaround can be effected by changes to the app only, without also having to patch and compile a replacement Alsa. Whilst it is by no means ideal, it does overcome the underlying problem successfully. Details of the workaround could be added to the OSS-Emulation.html document. Patch for 1.0.14rc4 is attached for consideration, together with example portaudio patch. Regards Alan

[alsa-devel] [PATCH] ALSA: Fix prototype for snd_soc_dai_link.init() function pointer
by Timur Tabi 04 Jun '07

04 Jun '07

Change the snd_soc_dai_link.init() function to take a pointer to the corresponding snd_soc_dai_link structure, instead of a pointer to a snd_soc_codec structure.

[alsa-devel] SALSA-Lib version 0.0.1 release
by Takashi Iwai 04 Jun '07

04 Jun '07

Hi all, I created a small replacement of ALSA-library, mainly for embedded systems with limited resources. The library is named as "SALSA-Lib" (too easy, eh?) It has no plugin layer but only hw layer, thus no sexy features like dmix and format conversions are available. It supports no shiny and complex configuration files. And it supports no sequencer. The only goal of this library is the reduction of the size of library and running binaries by inlining functions with direct syscalls. The library is designed to be source-level API compatible with the normal alsa-lib 1.0.14. Note that it is _not_ designed to be binary-compatible at all, and it will be never so. The first released version 0.0.1 is available at: ftp://ftp.suse.com/pub/people/tiwai/salsa-lib/salsa-lib-0.0.1.tar.bz2 The package is released under LGPL as well as the original alsa-lib. I've tested it only on i386, and tests on other architectures would be greatly appreciated. (And, no, I didn't make it on HG tree yet.) Takashi

[alsa-devel] Datasheet Needed
by chris＠idlelion.net 04 Jun '07

04 Jun '07

(working on bug #305) I'm looking for a proper datasheet on the Cirrus Logic / Crystal Semiconductor CS4624 (or CS4622) sound chip. It's used in a number of popular laptops made around 1999-2001. I don't need the 7- or 8-page feature list, or the 30 (or so) page reference design document. I need register lists and theory of operation and a discussion of power modes. The chip was end-of-lifed in 2004. Many thanks, Chris

[alsa-devel] Problem with ncurses and alsamixer (cannot open terminal: vt100 or xterm)
by David Topper 04 Jun '07

04 Jun '07

I finally managed to get the alsa-1.0.4 utils to compile on an ARM based SBC. When I launch alsamixer, however, I get an error: Error opening terminal: xterm When I ssh into the board. Or: Error opening terminal: vt100 When connected via serial cable. I suspect this has something to do with the linking (or lack thereof) of alsamixer for ncurses. The ncurrses library, by the way, I cross compiled with the following command: CC=/opt/crosstool/arm-unknown-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/arm-unknown-linux-gnu-gcc ./configure --host=arm-linux --prefix=/home/topper/ts-packages/ --exec-prefix=/home/topper/ts-packages/ But for the alsa utils, I simple ran ./configure, and the script detected the ncurses library, ran through and compiled. Yet, something seems amuck because: root@ts7000:root# ldd /bin/alsamixer libasound.so.2 => /lib/libasound.so.2 (0x2aac8000) libm.so.6 => /lib/libm.so.6 (0x2ab6f000) libdl.so.2 => /lib/libdl.so.2 (0x2abe9000) libpthread.so.0 => /lib/libpthread.so.0 (0x2abf3000) libc.so.6 => /lib/libc.so.6 (0x2ac4b000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaab000) Whereas on my Linux Intel laptop: awn:~$ ldd /usr/bin/alsamixer libncurses.so.5 => /lib/libncurses.so.5 (0x4002c000) libasound.so.2 => /usr/lib/libasound.so.2 (0x40069000) libm.so.6 => /lib/libm.so.6 (0x4010d000) libdl.so.2 => /lib/libdl.so.2 (0x40130000) libpthread.so.0 => /lib/libpthread.so.0 (0x40133000) libc.so.6 => /lib/libc.so.6 (0x40184000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) So I have two questions: 1. How might ensure proper linking of the ncurses library. 2. Is there another way to tell alsa to activate various cards, set volume, etc.. so I can test to see if the alsa driver is even working on this board.

[alsa-devel] snd_hda_intel: Conexant CX20551 (Waikiki)
by Edwin Smulders 03 Jun '07

03 Jun '07

Hi, I believe there's still a problem with the HDA Intel chip Conexant CX20551 (Waikiki) not working. However, im not entirely sure the problem the problem is with alsa, because it starts working when i boot with acpi=off (a fix suggested on the ubuntu forums, but not quite useful on a laptop [plus, it breaks my ethernet]) The reason I'm mailing is, can you confirm this is something alsa can/should/will fix or are we all looking in the wrong direction and this is really an acpi problem? If you can fix this or know of something that might work, I would be happy to hear it. I've attached my lspci -nv and cat /proc/asound/card0/codec\#* just in case. I would be happy to give you any more info you might need. ~~ Edwin

Hey gang, I'm trying to work on issue 305, suspend/resume for cs46xx. I'm running CentOS 5, so I'd like to work on what's current for that distribution first, and patch to latest if needed after that. I think I have the correct source package, but the only mention of cs46xx I could find in the source is a configuration file. Running make doesn't make the cs46xx module, AFAICT. Which source (package)(s) should I have? How do I track down the source file(s) I need to examine? Thanks, Chris

In that case, I think we can solve this problem as well as the PowerPC device tree problem in one shot, because they're basically the same problem. Anyway, let me see if I get this right: 1. The first function called is eti_b1_init(). 2. eti_b1_init() calls platform_device_add() to add an soc-audio class device and register the eti_b1_snd_devdata structure. 3. The registration causes a number of things to happen, one of which is a call to soc_probe(). 4. soc_probe() sees that the snd_soc_machine_eti_b1.probe is NULL, so that part is skipped. 3. soc_probe() sees that snd_soc_machine_eti_b1.dai_link->cpu_dai->probe is also NULL, so that part is skipped. (eti_b1_snd_devdata.machine == snd_soc_machine_eti_b1) 4. soc_probe() sees that soc_codec_dev_wm8731.probe is not NULL, so it calls wm8731_probe(). 5. wm8731_probe() registers an I2C driver. 6. The I2C class driver calls wm8731_i2c_driver.attach_adapter, which is wm8731_i2c_attach(). 7. wm8731_i2c_attach() calls i2c_probe(), which in turn calls wm8731_codec_probe() 8. wm8731_codec_probe() allocates a snd_soc_codec structure. 8. wm8731_codec_probe() calls wm8731_init(). This means that if there is no I2C support, wm8731_init() will never be called. 9. wm8731_init() initializes the snd_soc_codec structure. Question: why doesn't wm8731_probe() initialize the non-I2C parts of the snd_soc_codec structure? For example, snd_soc_codec.dai, snd_soc_codec.name, and snd_soc_codec.owner? That way, the snd_soc_codec structure will be properly initialized even when there's no I2C. 10. wm8731_init() calls snd_soc_new_pcms. 11. wm8731_init() exits, wm8731_codec_probe() exits, wm8731_i2c_attach() exits, and then wm8731_probe() exits. Control returns to soc_probe(). 12. soc_probe() notices that eti_b1_snd_devdata.platform.probe is NULL, so it skips that. Question: why don't you define a function for at91_soc_platform.probe, and in that function you can call snd_soc_new_pcms()? That way, you guarantee the codec driver's I2C interface is initialized before snd_soc_new_pcms() is called, and you avoid have PCM calls in the codec driver. >> ASOC and the machine driver should then work in tandem to decide which driver will do what >> and which capabilities are *actually* supported. *Something* needs to look at the entire >> system and say to each device, "Well, yes, I know about this little feature of yours, but >> we're just not going to support that today." >> > > The machine driver pretty much already does this.

[alsa-devel] Configure problems for alsa-utils-1.0.4
by David Topper 01 Jun '07

So I've managed to compile alsa-drivers-1.0.4 for ARM. I can even load the modules. I've also successfully compiled alsa-libs-1.0.4 ... but I had to do it on the board. Cross compiling simply didn't seem to work. I've been using --prefix=/ and --exec-prefix=/ for configures. But when I do ./configure --prefix=/ --exec-prefix=/ for alsa-utils-1.0.4 it fails with: checking for libasound headers version >= 0.9.0... not present. configure: error: Sufficiently new version of libasound not found. But they're there, for sure. Perhaps it doesn't like looking in /include/alsa? Thanks, DT

[alsa-devel] snd_soc_dai_link.init()
by Timur Tabi 01 Jun '07

01 Jun '07

Liam, Why does the init() function pointer in the snd_soc_dai_link structure take a snd_soc_codec pointer? Wouldn't it make more sense for it to take a snd_soc_dai_link pointer? That way, I could use the init() function to initialize the structure. I'm trying to write a function that will initialize the codec_dai pointer. I thought I could use snd_soc_dai_link.init(), but I don't know how to get the pointer to the snd_soc_dai_link structure from a snd_soc_codec structure. /* SoC machine DAI configuration, glues a codec and cpu DAI together */ struct snd_soc_dai_link { char *name; /* Codec name */ char *stream_name; /* Stream name */ /* DAI */ struct snd_soc_codec_dai *codec_dai; struct snd_soc_cpu_dai *cpu_dai; /* machine stream operations */ struct snd_soc_ops *ops; /* codec/machine specific init - e.g. add machine controls */ int (*init)(struct snd_soc_codec *codec); }; -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Power management state flow in ALSA
by Nobin Mathew 01 Jun '07

01 Jun '07

I am having a doubt regarding ALSA power management. My understanding of APM suspend() is like this. Freeze the ALSA apps Call ALSA driver suspend () in the ALSA suspend() function it saves the current state of substream and changes the state of substream to SUSPENDED. My understanding of APM resume() is like this Call ALSA driver resume () Activate the ALSA apps In ALSA resume function it restores the saved state of substream. So my question is when ALSA app will get to know the SUSPENDED state of substream.??? I am using linux kernel 2.6.17 ALSA driver version 1.0.11rc4 ASoC patch version 0.12.4

[alsa-devel] ASoC and a codec that can't be controlled
by Timur Tabi 31 May '07

31 May '07

I'm working on some ASoC drivers for a new board, and we're using a CS4270. The CS4270 is interesting in that if it is connected in stand-alone mode, there is no way to configure it. The board wirings determine all the parameters. Therefore, my CS4270 codec driver will probably be very skimpy. My question is: does this mean that my cs4270.c file will *never* call these functions: snd_ctl_add snd_soc_cnew snd_soc_dapm_new_control snd_soc_dapm_connect_input snd_soc_dapm_new_widgets These are the functions used to add new controls and widgets. So how does ALSA know that it needs to call my I2S driver *instead* of my codec driver to do stuff like change volume? -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Hardware-accelerated OpenAL support with ALSA?
by Chris Rankin 31 May '07

31 May '07

Hi, I have been looking at getting OpenAL working on my machine, since OpenAL is the only way that games under Windows Vista can now provide hardware-accelerated sound effects. This suggests that a lot of PC games could be adding OpenAL support soon, which means that it would be handy if Linux had an efficient native OpenAL implementation that Wine could wrap. Fedora Core does provide an OpenAL library from www.openal.org, but it looks as if this library's ALSA backend does not provide any hardware acceleration. (I have an "Audigy 2 ZS" sound card, which can at least support hardware mixing.) Various alternative ALSA-based solutions do seem to exist on the Web, e.g. http://dino.e4a.it/openal-alsa/ and http://www.lost.org.uk/openal.html However, it seems to me that OpenAL support would be better served as an actual ALSA package that distros would be able to ship. Are there any plans to provide official OpenAL support in ALSA, please? Thanks for any information, Chris P.S. My Audigy 2 also seems to have EAX support. Does the ALSA driver support that functionality too? I can't say that "World of Warcraft" seems to use it, although Wine's DirectSound3D support still has lots of gaps. _________________________________________________________ Inbox cluttering up with junk?

[alsa-devel] Userspace Device Driver
by Klaus Zimmermann 31 May '07

31 May '07

Greetings List, on various places on the alsa site I read about the possibility of writing a userspace device driver. I am interested thatin, since I have a nice Edirol FA-66 ieee1394 interface which works nicely under jack with the ffado (http://ffado.org , former freebob) driver. >From what I read it seems I could either write an external plugin to the alsa-lib, which would be truly userspace and fine except I it would always have to be configured from .asoundrc and would probably not be found by legacy programs like ekiga. Or I could get really messy and have a userspace daemon relay audio data between the ffado library, i.e. librawieee1394, and a yet to be written alsa-driver module. This would at least yield the advantage, that the driver was indistinguishable from a true hardware driver. So: Is it possible to write a userspace driver that is indistinguishable from a hardware driver? TIA Klaus Zimmermann P.S.: I am aware of the jackplug plugin. However even with very conservative buffer settings I get underruns and x-runs quickly leading to a failing jack :(

I have pasted my code below Regards, Ashlesha. <snip> I've been doing some thinking about what you are trying to accomplish and have a suggestion. I think you would be better off letting jack handle the back end/sound portion. Run a daemon/service listening on an arbitrary tcp/ip port. On startup it initializes alsa and jack. When it receives a request, it forks a process which opens a new channel on jack and creates a buffer for it. It then plays the sound it receives on that link via jack, silence when the buffer is empty. You would have to write client software for the user on the network to contact your daemon/service. You might even find something like this already out there.

[alsa-devel] How the dma interrupt handlers have been registered in ALSA?
by Pharaoh . 30 May '07

30 May '07

Hi I am referring omap-alsa-dma.c and the related codec files. We usually register the IRQ handler by calling request_irq() function but in this mentioned files the IRQ handler etc is defined but it is not registered anywhere i.e. request_irq is not used anywhere. Is there any other way of registering irq handlers? The irq handlers address is passed to omap_request_dma, but there also it is not registered. I am missing the entire thing?

It sounds to me like you want to have a thread running that accepts input from arbitrary processes and puts it in the main buffer. Then when the alsa callback occurs you want to take any new sound samples and send them to alsa. If that is the case, it makes more sense for the main buffer to be the circular buffer and the alsa buffer to be just a regular buffer. That's just personal preference though. As far as the handle error, I don't know what it means beyond what it says. You would have to look in the sources for the alsa library to see what causes that error to be generated. I don't see anything wrong in the logic of the code below, but the output indicates that you are not keeping up with the play rate. This is astonishing. At each play you can see that the available room in the buffer grows larger until larger than 1000, the buffer you have allocated. I'm not sure what infinite loop means and how your program is recovering from it. I presume that is where the time is being eaten up that isn't allowing you to keep up with the requests for data. I don't think you need to check if there is room when you get a callback. You should be able to just write the data to alsa using the writei call. i.e. eliminate the snd_pcm_avail_update call. I'm not familiar enough with alsa to help you further.

Second: We do not have a PCI Bus. It is an embedded system with an OCP-Bus (aka OPB). The ML403 holds a SoC with PPC and FPGA. So the only difference between DMA with bursts and a dedicated memory (as far as we do see it) is the amount of time the bus gets occupied. With dedicated memory the system will (hopefully ;-)) do a burst write each period. So what happens in DMA case (except the more complex hardware as the DMA controller has to be written (in VHDL) as well and even more memory is located at an more complex bus (PLB - processor local bus): the bus will be occupied twice: (1) CPU writes data to memory. --> start DMA --> (2) Controller fetches data from memory. While (2) is in progress the poor CPU is "disconnected" from the bus. In an embedded system with a not too powerful CPU (PPC 405 @300MHz) this might be quite inefficient. Or did we miss something?

[alsa-devel] Question on snd_soc_dai_link
by Timur Tabi 29 May '07

29 May '07

I have a question about these DAI structs for ASoC. Let's take eti_b1_wm8731.c as an example. It contains this structure: static struct snd_soc_dai_link eti_b1_dai = { .name = "WM8731", .stream_name = "WM8731", .cpu_dai = &at91_i2s_dai[1], .codec_dai = &wm8731_dai, .init = eti_b1_wm8731_init, .ops = &eti_b1_ops, }; Notice that the .cpu_dai field is hard-coded to use the 2nd I2S device on the AT91. The problem I'm having with this approach is that everything is hard-coded. On PowerPC, this approach doesn't work well, because we have a "device tree" that dictates what devices are present on the SOC. For a Freescale SOC that has two I2S devices (for example), both devices would be listed in the device tree, with the base address of the memory-mapped registers. This means that a Freescale I2S driver would have its 'probe' function called (much like PCI does) each time the kernel processes an I2S node in the device tree. This means that when the machine driver (which has the snd_soc_dai_link structure) loads, there's no guarantee that the I2S driver has also loaded and the probe functions have been called. It gets even more complicated if only one I2S device has a codec connected to it, because then I need to kmalloc the snd_soc_cpu_dai structures and somehow tell the snd_soc_dai_link structure which one to use. Has any thought been given to making these structures more dynamic and handling interdependencies among the drivers? As it stands now, it looks like I'm going to have to hard-code everything in the drivers and break the device tree paradigm. -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] ICE1724 alsa driver
by Rossco 29 May '07

29 May '07

Hi, I hope someone can help me. (tried the user list but no response) I have a hitpoint 7.1ch Envy24ht-s based card with the usual vt1616 multichannel codec and the wolfson WM8728. The card is recognised as a chaintech av710 with the only difference being that the card has spdif in as well as out. It appears to be physically similar to the maddog entertainer (would be good to know if this is also recognised as an AV710) By default 2 channel stereo in played through the "front" channel of the card through the vt1616 codec and I appear to be able to set spdif out through the mixer (but dont have another device to test at the moment). I have been able to change default output to go through the wolfson dac through an asound.state file posted on the web. I have to admit I do not quite understand what the file has done as it only appears to have removed some of the controls rather than change or add anything. Only two devices are detected for the card the vt1616 and IEC958, neither are shown as having any subdevices, therefore I am unsure how the asound.state file was able to address the wolfson chip which requires i2s input rather ac-link. This seems to indicate i2s and ac-link modes of the envy24ht-s chip are active. Most AV710 users seem happy enough to be able to route to toslink out and/or the higher quality wolfson chip, therefore there is little discussion of addressing the other channels of the card. I really want to be able to address each of the channels of the card so that I can use the convolution programme Brutefir with the card to create a multiway crossover for my loudspeakers. Is there anyway I can define each of the cards outputs so that I can select to send audio to any one of them? I am also keen to get the spdif in working and particularly the syncing to spdif in of the clock that the ice1724 chip supports. Can these features be added to the driver? Please advise of any required info, I have all the datasheets and can trace chip pins also. Thanks in advance. Ross

Playing with the buffer position in this way is always dangerous, because it's really hard to predict the final result in the multitasking environment. Think about these proposals: 1) what sample (ring buffer) rewritting is supposed to do - maybe you can change only not yet commited samples with satisfactory results 2) use a small ALSA ring buffer and use own "big" ring buffer for changes before you commit samples to ALSA's ring buffer - you'll increase a bit sample flow latency, but you can do anything you want (you just add extra buffering to avoid rewind / forward for ALSA API) 3) fix (or better implement) dmix plugin rewind function Jaroslav ----- Jaroslav Kysela <perex(a)suse.cz> Linux Kernel Sound Maintainer ALSA Project, SUSE Labs

[alsa-devel] [ALSA] ALSA Power Management, Drivers behaving unexpectedly after suspend/resume cycle
by Nobin Mathew 28 May '07

28 May '07

I am implementing power management in my ALSA sound drivers. ALSA drivers are not working properly after resume. All registers values are proper and I am able to read back the codec register contents. If I do a playback after resume then I am getting lots of "underrun". After a reboot playback is working fine. Is there any known issues with ALSA power management? Why Ubuntu and Redhat does ALSA modules removal before suspend and insertion after resume?

[alsa-devel] Reasonable sound hardware parameters?
by Joachim Förster 28 May '07

28 May '07

Hi ALSA devs, as I already described in one of my last posts on the list, I'm going to write a ALSA driver for a sound controller which will also be "written" at the same time (VHDL for FPGA) - on top of an embedded system (Xilinx ML403 EvalBoard, PowerPC 405). We will do playback feature only. The point is, that we will have _no_ real DMA and we don't want to use the copy/silence or ack/workqueue (with intermediate buffer). So we decided to move the ring buffer, which usually exists in RAM into the sound controller and handle it as some kind of device IO memory, which should be mmap'able (kernel function io_remap_pfn_range()). So, the important goal is, to have mmap feature in the ALSA driver. First question: To implement mmap on such kind of device IO memory, I have to use snd_pcm_lib_mmap_iomem() as mmap() callback - like it is used in the rme32 driver, right? Second question: Do the following parameters make sense regarding the size of the HW ring buffer and period sizes: .buffer_bytes_max=16*1024; .period_bytes_max=8*1024; .period_bytes_min=?? resonable value ?? .periods_min=2; .periods_max=?? resonable value ?? Furthermore, the sound controller will fire an interrupt after one period is played. Are there any arguments against these values? Any comments? Thanks, Joachim

[alsa-devel] alsa playback channel interleaving question

Hi, Earlier this year I wrote to this list: > I am trying to write an alsa driver for my audiowerk8 soundcard. > The aw8 uses a Philips saa7146 chipset. There are 2 capture and > 8 playback channels mapped on the saa7146's DMA as follows: > > DMA1: 2xcapture > DMA2: 4xplayback > DMA3: 4xplayback > > Sample format is 16bit. > > Frame format is as follows: > (A number corresponds to a channel, a stereo channel-pair is embraced > by [] and 1 digit corresponds to one sample byte) > > capture channels [0,1] on DMA1: 00--11-- > playback channels [2,3],[4,5] on DMA2: 22443355 > playback channels [6,7],[8,9] on DMA3: 66887799 I tried to find a way to handle this in the card, but this special interleaving for the playback channels is by hardware restriction and can't be worked around in the soundcard itself. AFAIK alsa provides the samples interleaved like 22334455 (66778899). To avoid channel switching I guess some special processing in the alsa driver is required. Where is this done best? Do I have to move around the samples in the interrupt handler or does alsa provide some (possibly better) means to achive the correct (for the soundcard) interleaving? Regards, Matthias

[alsa-devel] Suggestion for getting alsa to use Conexant
by Victor Schneider 26 May '07

26 May '07

How about being able to parameterize Alsa modules so that the intel 80xm module finds any hda modem that also acts as an Intel hda chip? I am referring to the Conexant combination modem and hda chip that gets identified as "Conexant Waikiki" by alsamixer, but that 80xm can't find as a modem. Giving the 80xm module the device:identifier value to override its detection of the Intel version of the Conexant hda modem might let slmodemd work.

Re: [alsa-devel] [RFC] [PATCH 0/2] ASoC sound support for SMDK2440boards

2007/5/24, Jose Henrique Spahn Torres <jose.torres(a)eldorado.org.br>: > I have a SMDK2410 and I am trying to run kernel 2.6.20 on it. The kernel > is running Ok, but the sound is dead. I gonna try your patch and I would > like to know which files from the RK's patch have you used? The attached two patches should enable the sound support fully. One of them adds the l3-bus, the other one the necessary Kconfig and Makefile changes, along with an ASoC hack. Add this patch also: http://mailman.alsa-project.org/pipermail/alsa-devel/2007-May/001105.html Everything should apply cleanly to 2.6.22-rc2, but probably also to 2.6.21. Zoltan

[alsa-devel] Sound on MSI S420
by Baruch Even 25 May '07

25 May '07

Hello, I've succeeded by guessing to get my MSI S420 laptop sound to work. Attached is a one-liner patch to do that. The patch is against kernel 2.6.22-rc2. Since the patch is based on guesswork it might not be optimal but it does work for me. Baruch

[alsa-devel] Testing ALSA and OSS drivers
by Pharaoh . 24 May '07

24 May '07

Hi I am planning to write an ALSA driver for an OMAP based board, I already have an OSS driver written for my board, but it is a 2.4 kernel. Question: I am trying to bring up Linux for my board (the board is supported), how can I test whether the oss drivers are working fine or not? I just have to check whether operations like playback and recording etc work as expected. Any pointers will be helpful. Regards, Pharaoh.

[alsa-devel] Default Sample rate Conversion
by Prabhu Sivaraja 24 May '07

24 May '07

Does ALSA automatically convert to my devices sample rate? My alsa.conf file is below pcm.mix { type dmix ipc_key 1024 slave { pcm "hw:0,0" rate 48000 } } pcm.!default { type plug slave.pcm "mix" } When I play a 32KHz file with aplay does it get up sampled to my device's 48KHz sample rate? I am assuming it does as it plays just fine but I am not sure where the upsampling happens? Thanks.

[alsa-devel] [RFC] [PATCH 0/2] ASoC sound support for SMDK2440 boards
by Zoltan Devai 24 May '07

24 May '07

Hi, The following patches are the first working version of drivers for the UDA1341 codec and SMDK2440 boards. Any comments for improvement are welcome. I also would like to ask for help in the following topics: - The codec requires an L3-bus driver. I'm using one made by RMK, but it's not mainline, and probably needs adoption to the driver model. (http://lkml.org/lkml/2005/10/28/194) It could also make more sense to integrate the driver into the i2c or spi subsystems, or just make it a S3C24xx specific gpio hack. Any volunteers ? - I only have access to a SMDK2440 board. Could someone verify if this would work on other SMDK's as well ? Regards, Zoltan

[alsa-devel] [PATCH 2/2] Add support for Cyrix/NatSemi Geode SC5530 (VSA1)
by Ash Willis 24 May '07

24 May '07

Add support for the Cyrix/NatSemi Geode SC5530 chips. This driver is ported from oss/kahlua.c and is made up of two patches. Patch 1/2 adds some stuff to the SB layer to allow for some hardware quirks and is to be applied to alsa-kernel. Patch 2/2 adds the actual driver code to be applied to alsa-driver. Patch 2 depends on patch 1.

[alsa-devel] [PATCH 1/2] Add SB_HW_CS5530 to the SB code
by Ash Willis 23 May '07

23 May '07

Add support for the Cyrix/NatSemi Geode SC5530 chips. This driver is ported from oss/kahlua.c and is made up of two patches. Patch 1/2 adds some stuff to the SB layer to allow for some hardware quirks and is to be applied to alsa-kernel. Patch 2/2 adds the actual driver code to be applied to alsa-driver. Patch 2 depends on patch 1.

[alsa-devel] No state is present for card CMI8738
by Tomas Pospisek's Mailing Lists 23 May '07

23 May '07

Since alsa-user is rather ... errr ... silent, I dare to repost the same question here. I've seen that Alsa likes the Terratec cards, however since they're also based on the CMI chipset, and at least /my/ onboard CMI chipset here sucks badly I wonder what low cost card I can use? I hope somebody can give me a clue, *t PS: Mic input is barely loud enough with my onboard sound. Mic boost has no effect. -- ----------------------------------------------------------- Tomas Pospisek http://sourcepole.com - Linux & Open Source Solutions ----------------------------------------------------------- ---------- Forwarded message ---------- Date: Mon, 14 May 2007 14:39:36 +0200 (CEST) From: Tomas Pospisek's Mailing Lists <tpo2(a)sourcepole.ch> To: alsa-user(a)lists.sourceforge.net Subject: [Alsa-user] No state is present for card CMI8738 The following is my problem: $ alsactl -f .alsavoip restore No state is present for card CMI8738 I see this "sometimes".

Nevertheless, the behaveour is not consistent in between "s2ram"s and I don't know whether that has anything to do with it either.

I do know that the Lenovo support for the ALC861VD was added after 1.0.14rc4 snapshot was made. Try installing the most recent HG daily snapshot from ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver . If that doesn't fix it, rerun the alsa-info.sh script and repost the new data. -- Tobin Davis <tdavis(a)dsl-only.net>

[alsa-devel] bios update alters hda-intel and alsamixer
by Chris Pemberton 23 May '07

23 May '07

After updating the bios on a Lenovo notebook, my hda-intel sound "changed" Before the bios update I used kernel 2.6.20.3, external alsa-driver-1.0.14rc3 and the attached patch_realtek.c (in-kernel alsa wouldn't work) After the bios update I use just the alsa contained in kernel 2.6.20.3. Before bios update, my mixer contained many items: including master, front, mic, pcm, etc. Now it only contains master and pcm. So, I have a few questions: How can I determine what items are "supposed" to show up in alsamixer? Where can I submit my laptop soundcard information to help finalize support of this model/card? Thank you

Re: [alsa-devel] I don't understand snd_pcm_ops
by Ash Willis 22 May '07

22 May '07

> First off, I thought PCM stood for Pulse Code Modulation, but that > just describes the > format of the digital data. I don't understand what a PCM operation could be. Exactly, it described the format of the digital data used i audio processing. PCM does stand for pulse code modulation, but here it is a reference to a device that processes sample based digital audio i.e not midi etc. The ALSA middle layer (which includes PCM) takes care of all the common stuff that all drivers need to do. In sound drivers, we have multiple types of devices: PCM, midi, mixers etc. The PCM layer is responsible for doing all the digital audio work. I.e preparing the card for playback, initiaing transfer to and from the device etc. In short, if you want to playback or capture sound, you're going to need a PCM :) snd_pcm_ops is a structure of callbacks that relate to different events regarding the PCM interface. Use this to run your own code at specific events. I.e. it's most probable that you'll want to prepare the device in some manner before audio transfer starts, so you would put the code to do this into your prepare callback. > > I've seen documentation where PCM is considered an alternative to > I2S or AC97. But if you > look at eti_b1_wm8731.c, you'll see this: > > #include "at91-pcm.h" > #include "at91-i2s.h" > > So is the AT91 a PCM device or an I2S device??? None of these are alternatives to each other. They're all different things. The anser to your question would be that this is an i2c device that has a PCM. Have you read "Writing an ALSA driver"? It generally describes ALSA drivers as they relate to PCI, and how to write them, but it does a good job at explaining the general ALSA driver architecture. Ash =

[alsa-devel] Broken JACK plugin in alsa-plugins and a way to fix it.
by Jasiu 22 May '07

22 May '07

Hi. I want to note that JACK plugin in alsa-plugins in broken. (At least on my two systems.) It just plays for a few seconds and then stops hanging the application that was sending data to it. When it hangs jackd spits out this: subgraph starting at alsa-jack.jackP.3635.0 timed out (subgraph_wait_fd=7, status = 0, state = Running) What I want to note is that there is a fix to that and I would like it to be included in the tree. I'm not sure if it doesn't break anything else, but it works for me ok. Open pcm_jack.c and on the line 146 you'll find: write(jack->fd, buf, 1); /* for polling */ Deleting this seems to get rid of the problem. So please if you can patch this out. (I didn't make a patch myself since this is so tiny fix that it isn't really worth.) Cheers.

[alsa-devel] [PATCH] remove email addresses from MODULE_AUTHOR tag
by Rene Herman 22 May '07

22 May '07

Hi Takashi. Following up the recent MODULE_MAINTAINER discussion on LKML: http://lkml.org/lkml/2007/4/4/170 that concluded with MODULE_MAINTAINER not being a good idea, here's a patch that just deletes the email addresses from the MODULE_AUTHOR tags for ALSA. The email address is the problem I was trying to fix; with multiple current and non-current authors and maintainers who might not even be authors the address(es) available from the tag confuse the issue of whom to contact. It's moreover also information that easily outdated.

Re: [alsa-devel] Any standard ALSA application for simultaneous capture and playabck ?????
by Ciaccia 22 May '07

22 May '07

It looks like your application uses the following pattern: for (;;) { ReadFromAlsa WriteToAlsa } The ReadFormAlsa function waits for the capture channel to become available (i.e., there is some data to be read), while WriteToAlsa waits till the output buffer becomes available (i.e., it's possible to send data to the card without blocking). Ho do you know that this is the correct order? Could it be that you should before write data to the output buffer and then read data from the capture stream? I think your design is not completely correct... Look at my code, it works fine, but maybe there is a better approach...

> What are the complications in implementing simultaneous playback and > capture in ALSA??? I would like to add something to this post: what is the "best" way to program a full duplex application? I would like to have an application that does full-duplex, with the lowest possible latency and using less CPU resource as possible. I tried different approaches, but I was not completely satisfied with none of them.... Here is what I tried: -having two threads, one for playback and one for capture -defining 2 callbacks with async_handles and do all the processing in the callback functions (the last attempt) -using poll() to wait for one of the streams to be ready (see attached file fullduplex.c) Could some of you look at the attached code (it is not generic and contains lots of asserts, but it's supposed to work only on one single machine) and tell me if the last approach using poll is well structured? The main loop looks as following: > while (1) { > err = poll(ufds, 2, -1); > > for (i = 0; i < 2; i++) > { > if (snd_pcm_poll_descriptors_revents(handles[i], &ufds[i], 1, &revents) < 0) > { > printf("Error getting revents for %s\n", descriptors[i].name); > exit(1); > } > > if (revents & descriptors[i].poll_flag) > { > if (transfer_loop(handles[i], &first[i], descriptors[i].func) < 0) > { > printf("transfer_loop error for %s\n", descriptors[i].name); > // TODO exit?!? > } > } > } > } and the transfer_loop is a modified version of the loop found in the ALSA examples (pcm.c and latency.c).

[alsa-devel] Question on buffer size setting
by Allyn, Mark A 21 May '07

21 May '07

Hello: I am attempting to do some debugging of a new audio device, and I need to change the number of buffer descriptor list entries from the default of 16 to something much smaller, like 3. I am a bit confused while looking at the code. There seems to be a value labeled SNDRV_PCM_HW_PARAM_BUFFER_SIZE, but I can't figure how it is set. Is this a parameter that is passed as part of the configure prior to doing a make for the driver? Is this a parameter passed to modprobe when loading the driver? Thanks for your help. Mark

[alsa-devel] [PATCH] hda-intel: fix ASUS M2V detection
by Daniel Drake 21 May '07

21 May '07

Commit f32610edab47f36946d23b883aeae91e15986121 added ALC660VD support, but this caused a 2.6.21 regression for some users. The ASUS M2V device is now detected as ALC660VD rather than ALC660/861 but the PCI quirk was not carried over. This patch allows affected users to use audio again. http://bugzilla.kernel.org/show_bug.cgi?id=8273 https://bugs.gentoo.org/show_bug.cgi?id=178243 Signed-off-by: Daniel Drake <dsd(a)gentoo.org> Index: linux/sound/pci/hda/patch_realtek.c =================================================================== --- linux.orig/sound/pci/hda/patch_realtek.c +++ linux/sound/pci/hda/patch_realtek.c @@ -8384,7 +8384,6 @@ static struct snd_pci_quirk alc861_cfg_t SND_PCI_QUIRK(0x1043, 0x1338, "ASUS F2/3", ALC861_ASUS_LAPTOP), SND_PCI_QUIRK(0x1043, 0x13d7, "ASUS A9rp", ALC861_ASUS_LAPTOP), SND_PCI_QUIRK(0x1043, 0x1393, "ASUS", ALC861_ASUS), - SND_PCI_QUIRK(0x1043, 0x81e7, "ASUS", ALC660_3ST), SND_PCI_QUIRK(0x1179, 0xff00, "Toshiba", ALC861_TOSHIBA), SND_PCI_QUIRK(0x1179, 0xff10, "Toshiba", ALC861_TOSHIBA), SND_PCI_QUIRK(0x1584, 0x9072, "Uniwill m31", ALC861_UNIWILL_M31), @@ -8990,6 +8989,7 @@ static const char *alc861vd_models[ALC86 static struct snd_pci_quirk alc861vd_cfg_tbl[] = { SND_PCI_QUIRK(0x1043, 0x12e2, "Asus z35m", ALC660VD_3ST), SND_PCI_QUIRK(0x1043, 0x1339, "Asus G1", ALC660VD_3ST), + SND_PCI_QUIRK(0x1043, 0x81e7, "ASUS", ALC660VD_3ST), SND_PCI_QUIRK(0x10de, 0x03f0, "Realtek ALC660 demo", ALC660VD_3ST), SND_PCI_QUIRK(0x1019, 0xa88d, "Realtek ALC660 demo", ALC660VD_3ST),

I've just ported the SND_KAHLUA driver from OSS (patch not released yet). It covers the cs5530 (VSA1 only). I've named it snd-cs5530. This audio suffix seems a bit wacky to me.

[alsa-devel] Strange findings about the microphone in SigmaTel STAC9221 A1
by Ivan N. Zlatev 20 May '07

20 May '07

My hda-intel card is with the following codec: Codec: SigmaTel STAC9221 A1 Address: 0 Vendor Id: 0x83847680 Subsystem Id: 0x106b1700 Revision Id: 0x103401 I am using alsa 1.0.14rc4. I have a built-in microphone, which doesn't work, but today I found out something interesting. If I set the capture to minimum and place Mux at specific positions (Works with middle-ish and top, not bottom-ish) suddenly the mic started recording, but the quality is extremly bad. I have attached amixer and co. Does anyone have a clue what the issue is and how could possibly this little bit of random foundings to be used to possibly fix the mic? Regards. -- Ivan N.

[alsa-devel] ICE1712/1724 HW mixing?
by Rene Herman 19 May '07

19 May '07

Good day. I've been updating the TerraTec vendor page in the new wiki matrix: http://bugtrack.alsa-project.org/main/index.php/Matrix:Vendor-Terratec The problem with information that looks maintained though is that when something's _not_ mentioned, it might be interpreted to mean it's not actually working.... I have the older TerraTec cards (both ISA and PCI) but not any of the ICE1712/ICE1724 ones. Could someone verify/confirm that the ICE1712 (Envy24?) does not support 24-bit samples? And that ICE1724 supports only 32-bit in hardware? Does either chip/driver support hardware mixing? Filling out some of the Digital I/O tags for any Aureon card that you know would be nice as well.

[alsa-devel] I don't understand snd_pcm_ops
by Timur Tabi 19 May '07

19 May '07

I'm new to ALSA driver development, and I'm writing an SOC driver for new hardware. Can someone explain to me what the snd_pcm_ops structure is for? And it sounds like a stupid question, but after studying documentation and sample code, I'm still confused. First off, I thought PCM stood for Pulse Code Modulation, but that just describes the format of the digital data. I don't understand what a PCM operation could be. I've seen documentation where PCM is considered an alternative to I2S or AC97. But if you look at eti_b1_wm8731.c, you'll see this: #include "at91-pcm.h" #include "at91-i2s.h" So is the AT91 a PCM device or an I2S device??? Some background: I'm writing driver for a new SOC that has an I2S interface, and it's talking to a CS4270 codec, but the CS4270 codec is wired up in "stand-alone" mode, so there's no software configuration. -- Timur Tabi Linux Kernel Developer @ Freescale

Re: [alsa-devel] Alsa 1.0.13 (and others) does not work on ALC880
by Eric De Vito 19 May '07

19 May '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Tobin thank you for your so helpful recommendations ! In fact the key was probe_mask=1. But I did not see this option in the hda-intel module description :-( ... Now I added probe_mask)=1 in /etc/modprobe.d/alsa-base and it works either with 1.0.13 or 14rc4 :-). In fact when alsa is compiled with debug=detect this option is not necessary any more and sound works even without this option ... Does this option (probe_mask=1) limitates something in the sound system ? Is it better to not use it or is it painless for audio possibilities ? Thank you again for your help !!! Now to be more precise : 1) If I compile 14rc4 with debug=detect it can be compiled, modules can be inserted : - --> when inserted with # modprobe -v snd-hda-intel model=clevo I get in /var/log/messages : May 18 22:32:05 gondor kernel: [ 6012.711362] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 22:32:05 gondor kernel: [ 6012.774627] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:698: codec_mask = 0x3 May 18 22:32:06 gondor kernel: [ 6013.404197] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/hda_codec.c:1795: hda_codec: model 'clevo' is selected May 18 22:32:08 gondor kernel: [ 6015.083303] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:558: hda_intel: azx_get_response timeout, switching to polling mode... - -> when inserted with # modprobe -v snd-hda-intel model=clevo probe_mask=1 I get in /var/log/messages : May 18 22:32:50 gondor kernel: [ 6057.162063] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 22:32:50 gondor kernel: [ 6057.243574] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:698: codec_mask = 0x3 May 18 22:32:50 gondor kernel: [ 6057.873098] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/hda_codec.c:1795: hda_codec: model 'clevo' is selected 2) If I compile 14rc4 with debug=none it can be compiled, modules can be inserted : - --> when inserted with # modprobe -v snd-hda-intel model=clevo I get in /var/log/messages : May 18 19:39:46 gondor kernel: [ 2366.086099] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 19:39:49 gondor kernel: [ 2368.491630] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:558: hda_intel: azx_get_response timeout, switching to polling mode... and aplay gives : eric@gondor:/usr/src/modules/alsa-driver-1.0.14rc4$ aplay ALSA lib pcm_direct.c:867:(snd_pcm_direct_initialize_slave) snd_pcm_hw_params_any failed ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave aplay: main:550: Erreur d'ouverture audio: Argument invalide eric@gondor:/usr/src/modules/alsa-driver-1.0.14rc4$ - --> when inserted with # modprobe -v snd-hda-intel model=clevo probe_mask=1 May 18 19:41:45 gondor kernel: [ 2484.283312] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 And it works !!!!

[alsa-devel] Linux 2.6.21 regression with hda-intel (Conexant 5045)
by Gunter Ohrner 18 May '07

18 May '07

Hi! First of all: Sorry if this question is dumb or a fix should be obvious, but as a non-ALSA_expert I'm a bit a a loss at the moment... I searched the bugtracker and this list but could not find anything appropriate - most probably I missed a relevant post or didn't recognize it as being relevant... Any pointers are greatly appreciated! The situation is as follows: Using Linux 2.6.20.4, my laptop's soundcard works just fine. Using 2.6.21.1, it also works, but the headphone socket is dead. Plugging a headphone into it correctly mustes the internal speakers, but no sound is output via the headphones. Details: - Fujitsu Simens Amilo Si1520 - Codec: Conexant ID 5045 (as reported by Linux 2.6.20.4) Alsa device details between both Linux kernels differ completely, with Linux 2.6.20.4 only reporting a single a single analog PCM device and Linux 2.6.21.1 reporting a Conexant Analog and a Conexant Digital device. Should I still post the complete information from /proc/asound/* for both kernels? I tried applying conexant-test22.patch by Tobin Davis, but it does not seem to match the in-kernel ALSA code. It also does not seem to be related to the 5045 chip... Any ideas? Greetings, Gunter

That's really good to hear. Can you close the Bug entry #2732 then? (#2799 and #2820 can be closed too, if the 9600 Hz problem is solved) So thanks a lot ...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there It's support for the SI3054 Chip build into the Asus A8J Notebook Series. In Windows it's called "Motorola SM56". What do you mean with "sign-off"? I'm pretty happy when it walks into upstream, so that the requests on my homepage about how to patch alsa to run that modem are ceasing down. Just a small issue is left. With the alsa driver buildin into 2.6.19 slmodem is working, with any newer one (either standalone or buildin driver) we have a "hda-intel: invalid format_val, rate=9600, ch=1, format=2" error in dmesg. Seems something has been broken on that step (probably 1.0.13 to 1.0.14?). Sadly I'm not able to tell right now which alsa was included into 2.6.19. I'm trying to compare the files to get an idea what's wrong (#2799 and #2820 are reporting similar problems).

[alsa-devel] [PATCH] Add support for gain in softvol plugin
by Steve Longerbeam 18 May '07

18 May '07

Hi all, What do you think of this patch? I tested this using a stac9205 HDA codec with all sample formats supported by softvol (s32, s16, s24, big and little endian). The potential drawback I see is that softvol now has to use a intermediate long long multiply and add when computing amplified 32-bit samples. This wasn't an issue with the system I tested on, but possibly could be on slower machines. Also, are their any portability issues with using a long long datatype in alsa-lib? What is the list of embedded architectures that alsa-lib is targeted to build on? I see long long used in many other places in alsa-lib, so I'm hoping this isn't an issue. Steve

[alsa-devel] submitting a patch against the ALSA repos
by Adrian McMenamin 18 May '07

18 May '07

I have submitted my patch against the 2.6.21 kernel tree but I dare say I need to actually submit it against the alsa repos. I have a few questions: 1. Which set of sources do I patch - I assume alsa-driver - is that right? 2. How do I patch the firmware repo? As it is a binary I assume it is by some means other than patch(1) 3. This is a new architecture - there are no other SuperH drivers in alsa (afaik) - how do I add a new architecture? My memory is that when I tried this a year ago it was a bit of a nightmare.

[alsa-devel] Newbie questions regarding ALSA drivers
by Pharaoh . 17 May '07

17 May '07

Hi, I am very new to ALSA and just trying to get familier with the things, I have got few questions. 1. Is it true that all the OSS drivers are included only in directory linux/sound/oss and no where else? 2. There are arch specific folders like ARM, MIPS etc, so all the drivers in these folders are ALSA or OSS? 3. If I write a new driver for an OMAP based board, it should go in to linux/sound/arm/omap/ right? Or only ALSA drivers for this board should go there? 4. I have some old OSS drivers which were written for my board, do I need to make them ALSA drivers to be in line with the latest trend i.e. phasing out OSS drivers? -Pharaoh.

[alsa-devel] Audio driver for OMAP 730 based board - hpw to migrate from OSS to ALSA
by Pharaoh . 17 May '07

17 May '07

Hi I am new here and have slight idea about the Linux audio drivers. I am working on OMAP 730 based p2-sample board. AFAIK, there is no audio driver support for this board. I have found 2.4 drivers for the same board which I have ported to 2.6, but it is an OSS driver. So, the questions: 1. Has anyone written audio drivers for the above mentioned board? Any plans to make them open source? Any pointers will be useful regarding the same. 2. How should I go about migrating the OSS driver to ALSA, if something like this is necessary? 3. Any resources which will be helpful for writing ALSA drivers? Thanks & regards, Pharaoh.

Re: [alsa-devel] Can someone verify support for "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" ?
by ramkromberg＠mail.com 17 May '07

17 May '07

Yes, its like you said Rene, sb8 works although the sound is distorted and the module can't be removed... Later I can modprobe sgalaxy too, and the sound works without a hitch. Also since now I can compile some code - your "eeprom.c" compiles and works - I'm available for further testing... I also noticed that the binary you sent was 506kb while my compilation is 9kb, maybe you sent an early/later version with some additional includes for verbose ? I compiled it with "gcc -W -Wall -o eeprom eeprom.c" like you said (on my xubuntu 7.04 with build-essentials deb package installed). See attachment... Ram Kromberg ramkromberg(a)mail.com

You did it Rene !!! >sudo ./eeprom >sudo modprobe snd-sgalaxy sbport=0x220 wssport=0x530 It's working now !! I downloaded the binary (i didn't compile the code), chmod it, sudo it and the sgalaxy worked !!! the sb8 didn't work but I don't really care for that anyhow :-) For the record, I tested it on xubuntu 7.04 with xmms. Are you now planning to implement the code to the driver itself ? If you want me to test anything, let me know. i'm also considering installing slackware 11 since I need the preformance... THANKS !!!

[alsa-devel] Audio DMA buffer layout
by Markus Korber 16 May '07

16 May '07

Hi, I'm working with a custom sound chip with its own DMA hardware. The figure shows how the I2S DMA expects data to be prepared: IRQ1 +----------------+ | page_3 (right) |\ +----------------+ > double buffer 1 | page_2 (left) |/ IRQ0 +----------------+ | page_1 (right) |\ +----------------+ > double buffer 0 | page_0 (left) |/ +----------------+ The hardware has 2 double buffers, each containing left and right sample regions, i.e. it alternately transmits samples from page_0 and page_1, i.e. double buffer 0, then generates an interrupt and starts transmitting page_2 and page_3. After that another interrupt is generated and the process begins again with double buffer 0. So my question is, how to tell ALSA about this memory layout? Is it possible to operate in MMAP mode with SNDRV_PCM_INFO_NONINTERLEAVED? But then, how to tell the application that it should either fill double buffer 0 or 1? Or should I use RW mode and copy samples manually to another buffer? Or something else? SG-DMA? page()-callback? Best regards, Markus Korber

[alsa-devel] Steinberg Midex 8 driver development
by Norman Schleicher 16 May '07

16 May '07

I am currently on development for the Steinberg Midex8 USB driver. At the moment I can send notes to my Midi equipment via this device. Receiving is currently not implemented. My questions are: 1. Are there any tools to test the Alsa-Midi compatiblity ? 2. May I release some milestone results to the Alsa project ? Eg when the driver supports a small subset of send commands supported by midi. 3. What are the requirements to get released in an official alsa release package ? 4. Who is responsible for the version management ? Where can I read how the source code is organized in the repository and how to manage tags and branches for the development ?(I don't need an introduction how to use CVS, thats clear for me.) Regards Norman

[alsa-devel] Question to integrate a new driver
by Jean-Christian Hassler 16 May '07

Hello ! I wrote with a friend an ALSA driver for the emagic AUDIOWERK 2 soundcard. Now it works for the analog inputs/outputs. The project page is here : http://home.gna.org/aw2-alsa/index.html We have 2 questions to continue our work : 1- what is the way to submit our code to be integrated in the ALSA tree ? 2- We develop on two different version of the kernel (2.6.17-14 & 2.6.20) and the request_irq function prototype has changed between these two versions(the "struct pt_regs *" does no longer exists), how is this managed in ALSA ? Thank you

[alsa-devel] Jackd dies with snd-usb-usx2y (DRIVER NT error)
by Michael Bourgeous 15 May '07

15 May '07

Hi, I recently upgraded my system from 32-bit Ubuntu Edgy, with a custom hard-realtime-enabled 2.6.19 kernel, to 64-bit Ubuntu Feisty, with a hard-realtime-enabled 2.6.20 kernel. I also switched from an Athlon XP 2600 to an Athlon 64 X2 4600. In every way my new system should be faster, but jackd+usx2y worked on the last system, and doesn't work now. Here's what I'm doing to test the audio setup: ---------- sudo chrt -f 90 `pidof IRQ-23` # usb irq chrt -v -f 70 jackd -d alsa -dhw:1,2 -p 64 -n 2 # also tried defaults, and values up to -p 256 -n 8 chrt -v -f 25 zynaddsubfx ---------- After a short time (< 1 or 2 minutes) of switching instruments and playing notes with zynaddsubfx, all audio stops and jackd dies with the following error: ---------- ALSA: poll time out, polled for 7998858 usecs DRIVER NT: could not run driver cycle jack main caught signal 12 no message buffer overruns ---------- There is a corresponding message in the kernel log: ---------- [12546.132286] ALSA [...]/usx2yhwdeppcm.c:94: activ frame status -70. Most propably some hardware problem. ---------- I am loading the snd-usb-usx2y module with the nrpacks=1 option. I've gone through the Ubuntu HOWTOs I used to get things working on my last system (to some of which I have even contributed), and I am still having this problem. I already tried on alsa-user, so I'm taking this to the developer list (since I plan to help fix this if anybody will point me in the right direction). Additional note: I tried modifying the source code of the driver, commenting out the return statement after the "active status" error message. This began producing a new error message: "shouldn't be here with count=xx". So, I commented out the "return -EPIPE" after that error message, and now jackd doesn't crash. There are noticeable audio clicks whenever one of these errors occurs, but the driver seems to have no problem recovering, as audio continues. This error happens with the stock Ubuntu kernels as well. Thanks in advance, Mike Bourgeous

[alsa-devel] Multichannel capture support in E-MU 1212
by dustin＠seznam.cz 15 May '07

15 May '07

Hello, I am working together with Ctirad on supporting more capture channels in E-MU1212. So far we have managed to increase the number of channels from the default of 8 to 16 (A_FXWC2 = 0xffffffff, added new snd_emu10k1_audigy_dsp_convert_32_to_2x16 calls in emufx.c), there is still a number of issues to solve. I would like to get your opinion on the form of adding this support to the module. The options are either hard-coding the 16 capture channels into the code, assuming that users would prefer as many channels as possible and do the routing in jack, or introducing a module parameter emu1010-capture-channels (range e.g. 1 to 16 - untested yet) and leaving the default number at the existing 8. Furthermore, the PCMs other than efx seem to be of no use for the EMU-1x1x models, probably fairly confusing for new users. Would you find it OK, if they were removed for this specific card (if (emu->card_capabilities->emu1010)), keeping only the playback and capture PCM id 2? Thanks a lot for your suggestions. Based on them, I will prepare the patch (with comments on what we found out about the card - it is a pitty that the driver has almost no big-picture comments on the supported cards' specifics, making new developers spend a number of long nights going through the nontrivial code and guessing). Pavel.

[alsa-devel] intel8x0 / ALC655 no-capture solved
by Vegard Nossum 15 May '07

15 May '07

Hello, I've successfully debugged a problem I've had with being unable to record anything from microphones or line-in. Detailed information about the bug along with a temporary work-around can be found here: http://bugtrack.alsa-project.org/alsa-bug/view.php?id=3066 Now I'd just like to inform about the presence of the bug (at least I'm pretty sure it's a bug), and that it's solved by the means of a work-around. I'd be very happy to see a fix in the *code* for this, however. I'd even like to try it myself (heck, it's just a register write), but I'm not certain WHERE/WHEN to make the write, under which conditions, and for which range of cards (ie. is it specific to the ALC655 or ALC*, or perhaps Realtek chips, or should the fix be made for the Intel driver, or all AC'97 cards?). Guidance would be appreciated :) Maybe it's even as easy as a card config option, but I wouldn't know. Thanks. Kinds regards, Vegard Nossum PS: I'm not on the list, so please CC any replies.

[alsa-devel] soft vol

Hello Now that I have my pcm playback working with aplay with our at91 aSoc sound driver I would like to control the volume with softvol. I followed the instructions from http://alsa.opensrc.org/How_to_use_softvol_to_control_the_master_volume and I have the following asound.con file in /etc pcm.!default { type plug slave.pcm "softvol" } pcm.softvol { type softvol slave { pcm "plughw:0,0" } control { name "PCM volume" card 0 } } When I play a wav file directly to the device it works fine: # aplay -Dplughw:0,0 Front_Center.wav Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono but when I try to use the default softvol device I get the following output (and no sound): # aplay Front_Center.wav Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ALSA sound/core/control.c:1244: unknown ioctl = 0xc2c45512 ...

tried a lot of workarounds but none worked : boot options (irqpoll, pci=noacpi), single_cmd=1, position_fix=1, several models of hda-intel driver, I tried 1.0.13 and 1.0.14rc4 driver, with debug on... I must add that I already had this problem with previous distributions of Ubuntu. It worked with an old one (Breezy) then in Dapper and Edgy, it did worked ONLY when I self-compiled the driver with debug option enabled I never understood why. And now with Feisty/alsa 1.0.13/ubuntu kernel 2.6.20, or an ubuntu kernel with self-compiled alsa 1.0.14rc4, it does not work. I cannot have one sound :-(. Please help me .... Eric

[alsa-devel] default PCM volume
by Michel Benoit 15 May '07

15 May '07

Hello again, I am running alsa on a custom AT91SAM9260 arm based SOC board together with a a simple external PCM1725 codec. When using alsa-lib and the at91 soc driver (pcm+i2s) I can playback PCM samples using both aplay and test/pcm. Using softvol I can also reduce the volume of the playback. The problem I have is that the playback volume (with softvol=100%) is not very loud. The volume is the same even without the softvol plugin. The PCM codec has no hw volume control. According to our hw team the sound level should be much higher. Is there a default PCM attenuation (volume reduction) built into alsa lib? If so, how can it be adjusted? Thanks, Michel

[alsa-devel] [PATCH] SH7760 ASoC support
by Manuel Lauss 14 May '07

14 May '07

Hello, here goes attempt #3 for the SH7760 ASoC patch. Changes v2 -> v3 - added a generic demo board for AC97 Changes v1 -> v2 - incorporate Paul Mundt's suggestions - work around an oops when aplay is used in mmap mode ('aplay -M') by changing the allocation type to SNDRV_DMA_TYPE_CONTINUOUS As soon as I get Linux working on the EDOSK7780 board, I'll complete SH7780 support as well. Thanks, Manuel Lauss --- ALSA ASoC support for SH7760 - SH7760 DMA engine (dmabrg) - AC97 driver for HAC unit(s) found on SH7760/SH7780 - I2S driver for SSI unit(s) found on SH7760/SH7780 - generic SH7760-AC97 "demoboard" sound/soc/Kconfig | 1 + sound/soc/Makefile | 3 +- sound/soc/sh/Kconfig | 39 +++++ sound/soc/sh/Makefile | 14 ++ sound/soc/sh/dma-sh7760.c | 354 +++++++++++++++++++++++++++++++++++++++ sound/soc/sh/hac.c | 322 +++++++++++++++++++++++++++++++++++ sound/soc/sh/sh7760-ac97.c | 92 ++++++++++ sound/soc/sh/ssi.c | 400 ++++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 1224 insertions(+), 1 deletions(-) Signed-off-by: Manuel Lauss <mano(a)roarinelk.homelinux.net> diff --git a/sound/soc/Kconfig b/sound/soc/Kconfig index dccaa4b..3e3df26 100644 --- a/sound/soc/Kconfig +++ b/sound/soc/Kconfig @@ -26,6 +26,7 @@ menu "SoC Platforms" depends on SND_SOC source "sound/soc/at91/Kconfig" source "sound/soc/pxa/Kconfig" +source "sound/soc/sh/Kconfig" endmenu # Supported codecs diff --git a/sound/soc/Makefile b/sound/soc/Makefile index 98e6f49..e1c9a70 100644 --- a/sound/soc/Makefile +++ b/sound/soc/Makefile @@ -1,4 +1,5 @@ snd-soc-core-objs := soc-core.o soc-dapm.o obj-$(CONFIG_SND_SOC) += snd-soc-core.o -obj-$(CONFIG_SND_SOC) += codecs/ at91/ pxa/ +obj-$(CONFIG_SND_SOC) += codecs/ at91/ pxa/ sh/ + diff --git a/sound/soc/sh/Kconfig b/sound/soc/sh/Kconfig new file mode 100644 index 0000000..a332e51 --- /dev/null +++ b/sound/soc/sh/Kconfig @@ -0,0 +1,39 @@ +menu "SoC Audio support for SuperH" + +config SND_SOC_PCM_SH7760 + tristate "SoC Audio support for Renesas SH7760" + depends on CPU_SUBTYPE_SH7760 && SND_SOC + select SH_DMABRG + help + Enable this option for SH7760 AC97/I2S audio support. + + +## +## Audio unit modules +## + +config SND_SOC_SH4_HAC + select AC97_BUS + select SND_SOC_AC97_BUS + select SND_AC97_CODEC + tristate + +config SND_SOC_SH4_SSI + tristate + + + +## +## Boards +## + +config SND_SH7760_AC97 + tristate "SH7760 AC97 sound support" + depends on CPU_SUBTYPE_SH7760 && SND_SOC_PCM_SH7760 + select SND_SOC_SH4_HAC + select SND_SOC_AC97_CODEC + help + This option enables generic sound support for the first + AC97 unit of the SH7760. + +endmenu diff --git a/sound/soc/sh/Makefile b/sound/soc/sh/Makefile new file mode 100644 index 0000000..a8e8ab8 --- /dev/null +++ b/sound/soc/sh/Makefile @@ -0,0 +1,14 @@ +## DMA engines +snd-soc-dma-sh7760-objs := dma-sh7760.o +obj-$(CONFIG_SND_SOC_PCM_SH7760) += snd-soc-dma-sh7760.o + +## audio units found on some SH-4 +snd-soc-hac-objs := hac.o +snd-soc-ssi-objs := ssi.o +obj-$(CONFIG_SND_SOC_SH4_HAC) += snd-soc-hac.o +obj-$(CONFIG_SND_SOC_SH4_SSI) += snd-soc-ssi.o + +## boards +snd-soc-sh7760-ac97-objs := sh7760-ac97.o + +obj-$(CONFIG_SND_SH7760_AC97) += snd-soc-sh7760-ac97.o diff --git a/sound/soc/sh/dma-sh7760.c b/sound/soc/sh/dma-sh7760.c new file mode 100644 index 0000000..cdee374 --- /dev/null +++ b/sound/soc/sh/dma-sh7760.c @@ -0,0 +1,354 @@ +/* + * SH7760 ("camelot") DMABRG audio DMA unit support + * + * Copyright (C) 2007 Manuel Lauss <mano(a)roarinelk.homelinux.net> + * licensed under the terms outlined in the file COPYING at the root + * of the linux kernel sources. + * + * The SH7760 DMABRG provides 4 dma channels (2x rec, 2x play), which + * trigger an interrupt when one half of the programmed transfer size + * has been xmitted. + * + * FIXME: little-endian only for now + */ + +#include <linux/module.h> +#include <linux/init.h> +#include <linux/platform_device.h> +#include <linux/dma-mapping.h> +#include <sound/driver.h> +#include <sound/core.h> +#include <sound/pcm.h> +#include <sound/pcm_params.h> +#include <sound/soc.h> +#include <asm/dmabrg.h> + + +/* registers and bits */ +#define BRGATXSAR 0x00 +#define BRGARXDAR 0x04 +#define BRGATXTCR 0x08 +#define BRGARXTCR 0x0C +#define BRGACR 0x10 +#define BRGATXTCNT 0x14 +#define BRGARXTCNT 0x18 + +#define ACR_RAR (1 << 18) +#define ACR_RDS (1 << 17) +#define ACR_RDE (1 << 16) +#define ACR_TAR (1 << 2) +#define ACR_TDS (1 << 1) +#define ACR_TDE (1 << 0) + +/* receiver/transmitter data alignment */ +#define ACR_RAM_NONE (0 << 24) +#define ACR_RAM_4BYTE (1 << 24) +#define ACR_RAM_2WORD (2 << 24) +#define ACR_TAM_NONE (0 << 8) +#define ACR_TAM_4BYTE (1 << 8) +#define ACR_TAM_2WORD (2 << 8) + + +struct camelot_pcm { + unsigned long mmio; /* DMABRG audio channel control reg MMIO */ + unsigned int txid; /* ID of first DMABRG IRQ for this unit */ + + struct snd_pcm_substream *tx_ss; + unsigned long tx_period_size; + unsigned int tx_period; + + struct snd_pcm_substream *rx_ss; + unsigned long rx_period_size; + unsigned int rx_period; + +} cam_pcm_data[2] = { + { + .mmio = 0xFE3C0040, + .txid = DMABRGIRQ_A0TXF, + }, + { + .mmio = 0xFE3C0060, + .txid = DMABRGIRQ_A1TXF, + }, +}; + +#define BRGREG(x) (*(unsigned long *)(cam->mmio + (x))) + +/* + * set a minimum of 16kb per period, to avoid interrupt-"storm" and + * resulting skipping.

I must add that I already had this problem with previous distributions of Ubuntu. It worked with an old one (Breezy) then in Dapper and Edgy, it did worked ONLY when I self-compiled the driver with debug option enabled I never understood why.

[alsa-devel] alsa-lib functions reporting conflicting information with two sound cards
by nick smethurst 14 May '07

14 May '07

Hey guys I am rather confused that I am getting crossed information when calling snd_names_list and snd_pcm_info in order to gather information about pcm devices. I have two sound cards in my development pc: RME Digi 96/8 PCI and an onboard VIA 8237. I'm trying to develop a piece of code that generates a list of objects containing pcm device information, including information on virtual devices. My current idea is to use snd_names_list() to get a full list of devices, and then get information about them by opening each device and querying. The bizzare thing is that snd_names_list() is returning comments that do not agree with the associated device. For example, given the following code: #include <alsa/asoundlib.h> int main() { snd_devname_t * list; snd_config_update(); snd_names_list("pcm", &list); while (list) { if (!strcmp(list->name, "hw:0,0")) { printf("hw:0,0 comment: %s\n", list->comment); break; } list = list->next; } snd_names_list_free(list); snd_pcm_t * pcm; snd_pcm_info_t * pcm_info; snd_pcm_info_malloc(&pcm_info); snd_pcm_open(&pcm, "hw:0,0", SND_PCM_STREAM_PLAYBACK, 0); snd_pcm_info(pcm, pcm_info); printf("id: %s\n", snd_pcm_info_get_id(pcm_info)); snd_pcm_close(pcm); snd_pcm_info_free(pcm_info); return 0; } The result on my pc is: hw:0,0 comment: Physical Device - VIA 8237 (Duplex) id: Digi96 IEC958 So I'm apparently doing something very wrong here. I would like to ask if there is an easier and more reliable way of getting a list of pcm devices and querying them, and if not, what I am doing wrong here? Regards Nicholas

Hi all, the aoa drivers in 1.0.14rc4 are not usable. Compiling the modules there are much warnings "implicit declaration of function 'of_get_property'" Loading the module dmesg tells: snd_aoa: Unknown symbol of_get_property. rc3 out of 2.6.21 works fine. Any hints? Thanks Elimar -- You cannot propel yourself forward by patting yourself on the back.

I haven't touched this for a year, but after some small changes (to run queues) I can compile this and it runs well. Anyone care to comment on the prospects of getting it committed?

[alsa-devel] [PATCH] Coping with short replies in usbmixer
by thomas＠devbase.at 14 May '07

14 May '07

Hi, while trying to find out why a USB handset (Yealink P1K) frequently gets muted when changing volume, I found that short USB responses cause the problem. The function get_ctl_value(..) in usbmixer.c requests the state of a certain control and retries up to 10 times if an error occurs. However a short USB response is not treated as an error as neither the transfer flag URB_SHORT_NOT_OK is set nor is the return value of snd_usb_ctl_msg(..) compared with the requested amount of data. As a result the function get_ctl_value(..) might not retry the USB request but returns an unpredictable result without reporting an error. The attached patch forces the number of returned bytes to be at least val_len. It was generated from kernel version 2.6.21. If there are any issues with the patch please let me know. Otherwise I would be happy if it could be applied to the ALSA sources. Regards, -Thomas

[alsa-devel] e-mu 1212m and 1820(m) patch
by Ctirad Fertr 13 May '07

13 May '07

Hello, here is a little patch which enables ADAT and S/PDIF functionality. It adds possibility to sync with either S/PDIF or ADAT clock as well. 44.1/48kHz only, though it works pretty well for me. Regards, Ctirad
