[alsa-devel] Support for USB-Audio devices with Multiple configurations?
by Cameron Stone 19 May '09

19 May '09

I'm writing some firmware for a USB microphone array with multiple configurations, and I'm wondering if it's possible to tell ALSA which configuration to use in a module option or something (device_setup, perhaps). I've been looking through usbaudio.c in the kernel source (2.6.28-11-generic from the ubuntu Jaunty package), and I can't find any generic device configuration like that. If this is not possible, does anyone have any recommendations on how to implement this? I can imagine doing it using quirks for this particular USB_ID, but this seems like a fairly generic type of capability, so I'd like to make it general if possible. If anyone is wondering *why* I want multiple configurations: it's for bandwidth management. I have 8 channels, but I want to be able to sample 1 channel as fast as possible without wasting bandwidth on the other 7. I couldn't figure out a way to do that with a single configurations. Please let me know if you know one. ;-) Thanks, Cameron.

Is this driver the same source that creative released a few months back or has it been updated to support more features? Just Curious.

[alsa-devel] emu10k1 TRAM access ?
by mAdVax 19 May '09

19 May '09

Hello I would like to send some data to a DSP patch. I can use alsa controls (easy) but I need more : TRAM and lookup table. I read many lines of code, but all this is still quite obscure... Here are 3 questions : How can I fill the TRAM ? (from user space) How can I know which TRAM area has been allocated to a given patch ? Do 'lookup tables' work ? Some code samples will be greatly appreciated :) Thanks in advance. Note: I only know 2 sources of information about emu10k1 DSP, the alsa source code, and the old emu10k1 site at sourceforge. Xavier FYI: I already posted this message yesterday as a non-member, but it has not been moderated (I don't get an answer 24H later).

[alsa-devel] Output frequency configuration for I2S in beagleboard? (underrun problem)
by Ernesto Torres 18 May '09

18 May '09

Hi, I would like to know the actual configuration for the output of the Beagle Board I2S, from the OMAP35x Reference Manual, on page 2887: • Enable the Sample Rate Generator (take it out of reset).

I capture all actions from startup and from aplay but this function is never called. Do you know when it should be called or where we can find the div value? I'm having trouble adapting an external codec from the beagle, and I think it may be because of the output frequency from the beagle. I'm getting some underruns during playback(with aplay) and I don't know exactly where to begin. Suggestions are welcome. Thanks for your help Best regards, Ernesto

[alsa-devel] Problems with maintaining a separate alsa-driver in a distribution
by Ozan Çağlayan 18 May '09

18 May '09

Hi, I'm maintaining the ALSA stack as a separate alsa-driver using the supplied tarballs from www.alsa-project.org unlike some popular distros which uses the in-kernel sound/ stack. This has the advantage of quickly acting against latest quirk or driver support changes and pushing a driver update instead of whole the kernel update. But there is a big disadvantage that I'm not able to figure out how to solve: When we enable the SND Kconfig option in kernel, some other sound support for some DVB devices(e.g. SAA7134 sound support, etc.) are enabled as well. So if you're using the in-kernel ALSA, you can enable and use them happily but in my case, those additional sound supports can't be enabled in kernel. Is there a way to hack around this when a separate alsa-driver is used in a distro? Is it technically possible to patch those tiny drivers onto alsa-driver and compile them if the .config file from the kernel source has enabled those DVB devices? Or maybe I should enable ALSA in-kernel, compile those DVB sound stuff and remove the sound/ directory from the kernel package? (Even the idea sounds really *dirty*, dunno if it's technically possible too) Thanks, Ozan Caglayan http://www.pardus.org.tr/eng

[alsa-devel] [PATCH 0/1] Improved MacBook 3,1 support
by Torben Schulz 18 May '09

18 May '09

Hi guys, this patch improves the support for the MacBook 3,1, which had been handled by the "mbp3" model before. The "mbp3" model is quite inappropriate for the sound-chip of the MacBook 3,1 (RealTek ALC889A). Especially the lack of subwoofer support is one of the biggest disadvantages of this model (See bug 0004086). In contrast to the other models this model is part of the ALC883 configuration, which reflects the ALC889A sound-chip far better than the ALC882 configuration, which all other Apple models are part of. I myself own only a MacBook 3,1, but as far as I know it should also work for the MacBook 4,1 - perhaps even for other models. It would be good if someone could check this out... The new MacBook 3,1 model is called "mb31" and has the following features: - sound from the third speaker (aka "subwoofer") - 5.1 surround sound - speakers and subwoofer are muted when headphones are plugged in. - 4 channel modes - 2ch: speakers:front, subwoofer:CLFE, headphones:front, line:input - 4ch: speakers:front, subwoofer:CLFE, headphones:front, line:CLFE - 5ch: speakers:front, subwoofer:CLFE, headphones:rear, line:input - 6ch: speakers:front, subwoofer:off, headphones:rear, line:CLFE However, there are also two "issues": Speaker will be unmuted, when channel-mode is changed while headphones are plugged in. But this can easily be solved, by plugging the headphones out and in again or using the speaker switches in the mixer. I haven't managed to get "real" surround sound. It seems that the front channel is mapped to all other channels before they get to the mixers (front-left=front-left, front-right=front-right, rear-left=front-left, rear-right=front-right, LFE=front-right, center=front-right). The volume of each channel can be set individually through the mixer. However, this could also be an high configuration issue on my side (please tell me ^^)... Bai Torben

[alsa-devel] [PATCH 2/3] ASoC: TWL4030: Add control for selecting codec operation mode

Add a control for selecting the codec operation mode. TWL4030 codec has two modes: - Option 1. Audio only (4 audio DACs) - Option 2. Voice/Audio (2 audio DACs and voice ADC/DAC) Control is restricted when a stream is ongoing, since codec's operation mode cannot be changed on-the-fly.

[alsa-devel] [PATCH 0/1] ASoC: TWL4030: Headset ramp down fix
by Peter Ujfalusi 18 May '09

18 May '09

Hello, The following patch should fix (or at least makes it less intrusive) the 'tuck' phenomena on observed on the twl4030 Headset outputs when the codec is going to standby mode. I have debugged this with the scope and if we are not waiting RAMP_DELAY time, the VMID is cut before it reaching 0, which generates the 'tuck'. Note that I have not removed the control for the RAMP_DELAY configuration, the code will use that to calculate the needed delay (also the sysfreq is needed, which also stored). However I do think that one should not touch the RAMP_DELAY... It would be nice to hear from you guys, if it solves/softens the 'tuck'. --- Peter Ujfalusi (1): ASoC: TWL4030: Wait RAMP_DELAY on headsetl_event: POST_PMD sound/soc/codecs/twl4030.c | 20 ++++++++++++++++++++ 1 files changed, 20 insertions(+), 0 deletions(-)

No it doesn't, nRESET is on GPIO95, it's verified by hardware probing. See previous mails in this thread for the reason of these problems.

This is more or less what I'm trying to do, with the difference that I don't move samples from the ALSA ring buffer when they arrive but when the USB layer asks for more data. My trouble is that I don't get notified when new samples are written to the ALSA ring buffer, and I'm not sure to find out how many samples are present in the buffer. If I could get some kind of "sample written" notification, or better, compute the size of data present in the ring buffer, my problem would be (mostly) solved. From what I understand, such a notification isn't possible when the ALSA ring buffer is mmap'ed, as ALSA itself doesn't get notified. This makes the second approach (reading the number of available samples) better, except that some kind of "free-wheeling" mode makes it impossible under some circumstances. From what Takashi Iwai explained in a mail to Jon Smirl on alsa-devel ("appl_ptr and DMA overrun at end of stream"), "we have also mode when appl_ptr is not updated at all (when stop_threshold == boundary)". This free-wheeling mode seems to be used by dmix. Best regards, Laurent Pinchart

[alsa-devel] Another successful X-Fi driver test.
by A.Haq Abbad 16 May '09

16 May '09

Here are some details: System: Intel Core 2 Duo E6600 Asus P5W DH Motherboard X-Fi eXtreme Music Intel HD audio onboard Software: Advanced Linux Sound Architecture Driver Version 1.0.20. Compiled on May 16 2009 for kernel 2.6.28-11-generic (SMP). Running Kubuntu 9.04, with default packages. All major audio players tested and work fine. Aduiocious does not work with 24bit mode as reported before. System is stable, no issues encountered yet! Recording through the mic works flawlessly. Sound from speakers seem clear. Switching between intel HD onboard audio and xfi works fine, both enabled on the same system. P.S I installed the file alsa-driver-unstable-snapshot.tar.gz now my alsa version is 1.0.20 instead of .18, does that cause major issues? I thought the package will only install the module snd-ctxfi, not the whole alsa! or is that not possible. Let me know if you want me to run specific test. Regards.

[alsa-devel] FIXED by substituting 1.0.19 pcm_lib.c for 1.0.21 pcm_lib.c -> Re: ALSA 1.0.20 PCM Capture Problem (Does not happen on ALSA 1.0.19)
by Robert Krakora 16 May '09

16 May '09

I grabbed ALSA 1.0.20 and attempted to capture video from my Creative USB webcam and audio from my analog audio microphone. To my surprise there was audio being captured but only in bits and pieces, nothing audible. If I recorded the audio and played it back it sound like broken audio. I noticed this in the release notes: [ALSA] pcm-midlevel: Add more strict buffer position checks based on jiffies I assumed it had something to do with changes made in pcm_lib.c, so I replaced the ALSA 1.0.20 version of this file with the ALSA 1.0.19 version, rebuilt and I am now able to capture audio again from my analog microphone. I filed Bug Report 0004523 describing this problem.

[alsa-devel] Advice on ASoC support for series of boards
by Ben Dooks 15 May '09

15 May '09

I would like some advice before I start on a project to move our series of boards to the ASoC framework. All the boards shared the same I2S wiring and all but one have the same TI CODEC wired in similar configuration. The differences are in the presence and connection of a speaker AMP (GPIO controlled). Is there a standard method for binding an AMP to an driver, or is it necessary to have the AMPs in the driver itself? If not, what would people recommend to be the best example of this? -- Ben Q: What's a light-year? A: One-third less calories than a regular year.

[alsa-devel] How to set TWL4030 to Option2
by Lopez Cruz, Misael 15 May '09

15 May '09

I'm adding the voice dai to sdp3430 machine driver, but the codec's "twl4030_voice_startup" function has a requirement for voice to work: the codec has to be in option2. How can I switch the codec to option2 mode? There is no control for doing that, and the only way I see is to directly modify the reg cache, but I assume that is not the right way to do it. Could you please clarify? -Misa

[alsa-devel] Should snd_pcm_drop() interrupt snd_pcm_writei() call?
by Marek Peca 15 May '09

15 May '09

Hello, I would like to know, how should snd_pcm_drop() call influence snd_pcm_writei() being simultaneously executed. I expected, that after issuing snd_pcm_drop() (from another thread), the snd_pcm_write*() in progress should be terminated almost immediately with some return value (error or short write). According to my observation, this seem to work on ALSA lib & driver 1.0.14rc3, snd_ali5451. However, it never or almost never works on another machine with ALSA lib 1.0.16 (Debian package libasound2 [1.0.16-2], driver unknown, sorry). There, the snd_pcm_write*() _never_returns_ after snd_pcm_drop(), and remain stuck forever. I would like to ask you, which behaviour of snd_pcm_drop/snd_pcm_write* is the correct one. I suppose the snd_pcm_write*() should be interrupted, otherwise, an extra thread would be needed in many applications. However, I don't know, why does not it work in the later version of ALSA. I have not found the answer in Doxygen, and since I am real ALSA newbie, I gave up reading ALSA source, especially because I have seen different behaviour among two different versions. Excuse my impatience. Thank you for a clarification. Best regards, Marek.

[alsa-devel] Dynamically registering a codec
by Jon Smirl 14 May '09

14 May '09

On PowerPC the device tree is used to dynamically load the correct codec module. How am I supposed to get this dynamically loaded module registered? The WM8580 codec registers itself.

If I don't do this how am I supposed to dynamically find the DAI pointer so that I can call snd_soc_register_dais()? diff --git a/sound/soc/codecs/wm9712.c b/sound/soc/codecs/wm9712.c index 550c903..cb0e679 100644 --- a/sound/soc/codecs/wm9712.c +++ b/sound/soc/codecs/wm9712.c @@ -20,6 +20,7 @@ #include <sound/initval.h> #include <sound/soc.h> #include <sound/soc-dapm.h> +#include <sound/soc-of-simple.h> #include "wm9712.h" #define WM9712_VERSION "0.4" @@ -740,6 +741,39 @@ struct snd_soc_codec_device soc_codec_dev_wm9712 = { }; EXPORT_SYMBOL_GPL(soc_codec_dev_wm9712); +static int __init wm9712_probe(struct platform_device *pdev) +{ + snd_soc_register_dais(wm9712_dai, ARRAY_SIZE(wm9712_dai)); +#if defined(CONFIG_SND_SOC_OF_SIMPLE) + /* Tell the of_soc helper about this codec */ + of_snd_soc_register_codec(&soc_codec_dev_wm9712, pdev->dev.archdata.of_node, + wm9712_dai, ARRAY_SIZE(wm9712_dai), + pdev->dev.archdata.of_node); +#endif + return 0; +} + +static struct platform_driver wm9712_driver = +{ + .probe = wm9712_probe, + .driver = { + .name = "wm9712", + }, +}; + +static __init int wm9712_driver_init(void) +{ + return platform_driver_register(&wm9712_driver); +} + +static __exit void wm9712_driver_exit(void) +{ +} + +module_init(wm9712_driver_init); +module_exit(wm9712_driver_exit); + + MODULE_DESCRIPTION("ASoC WM9711/WM9712 driver"); MODULE_AUTHOR("Liam Girdwood"); MODULE_LICENSE("GPL"); -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] Intel HDA fix for Macbook 3,1 and newer
by Le Torbi 14 May '09

14 May '09

Hi guys, I'm new to this list and never contributed anything to such a big open-source project like ALSA, so please forgive me if I make some newbie mistakes. But back the the important stuff: I own a MacBook 3,1 and experienced some sound issues with this. I didn't have no sound, but the sound was quite low in quality and volume. After some research and a lot of wrong ways I stumbled upon bug 0004086 "MacBook 4,1 sounds tinny or not at all " in the ALSA bug tracking system (https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4086) and managed to fix it. Any details can be found in the bug report as well as a link to my patch. My questions now are: 1. Could an exprineced ALSA-Coder check my patch for bugs or "newbie code glitches"? 2. What do I have to do, to get my patch in the official code repository? Thanks in advance for any help. Bai Le Torbi

[alsa-devel] appl_ptr and DMA overrun at end of stream
by Jon Smirl 14 May '09

14 May '09

I am having problem with DMA overrun at the end of the audio stream. Is there an official way to know the address of the last valid audio sample? mpc5200 ac97 is keeping a bunch of descriptors queued in a loop to continuously play music. I believe this is the way ALSA wants it. Now say the last period is half full. ALSA fills the other half with silence. When that period finishes playing it will generate an interrupt. ALSA comes back from that interrupt with trigger(STOP). But, our CPU is slow compared to a 3Ghz desktop, there is considerable latency from the period end interrupt to trigger(STOP) getting called. So the DMA hardware starts playing the next period before trigger(STOP) can get the DMA stopped. I turned off tried turning off BestComm, flushing the FIFO, and turning off the audio clocks. None can be done fast enough. That next period contains stale data from further back in the stream. When the front part of it plays it makes a burst of noise. What I need is the address of the end of valid data in the buffer. I need that address so that I can program the DMA automatically stop at end of stream and not overrun. Search around in the guys of ALSA I found appl_ptr. I can use appl_ptr to determine the location of end of stream and prevent DMA overrun. When there is no valid data I don't enqueue the descriptor. s->appl_ptr track the previous value of s->runtime->control->appl_ptr. The difference between these two is the amount of valid data in the buffer. When this difference goes to zero, I stop queue new buffers to ALSA. That fixes the DMA overrun. static void psc_dma_bcom_enqueue_next_buffer(struct psc_dma_stream *s) { struct bcom_bd *bd; while (s->appl_ptr < s->runtime->control->appl_ptr) { if (bcom_queue_full(s->bcom_task)) return; s->appl_ptr += s->period_size; /* Prepare and enqueue the next buffer descriptor */ bd = bcom_prepare_next_buffer(s->bcom_task); bd->status = s->period_bytes; bd->data[0] = s->period_next_pt; bcom_submit_next_buffer(s->bcom_task, NULL); /* Update for next period */ s->period_next_pt += s->period_bytes; if (s->period_next_pt >= s->period_end) s->period_next_pt = s->period_start; } } -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] [RFC] ALSA vs. dedicated char device for a USB Audio Class gadget driver
by Laurent Pinchart 14 May '09

14 May '09

Hi everybody. Linux provides a USB Audio Class (UAC) driver on the USB host side, but a UAC gadget driver on the USB device side is currently missing. Considering plugging in this hole, I'm looking at userspace <-> kernelspace APIs. In a nutshell (let's consider recording, where the device appears to the host as a USB microphone), the kernel driver needs to be fed with audio data from a userspace application and stream those data on USB. Audio data can come from a real microphone (through an ALSA driver), a file, a network socket, ... the driver will not care. I need an API to transfer audio data from userspace to kernelspace. I initially thought about ALSA, but it turns out some assumptions made by ALSA are not fulfilled by my system. One of the most serious problems is that the UAC gadget driver doesn't have any audio clock. The only hardware clock available is the USB device controller interrupts generated at the USB transfer rate, and those are much faster than the audio sample rate. This will cause buffer underruns that I need to handle. I can thing of 3 solutions to solve this issue, and I'd like your opinion on them. 1. Get the userspace application to provide a clock to the driver. This could be done by writing to a /proc file, a special char device, or even by adding an ioctl to ALSA. Every time the driver receives a clock tick it would transfer one period of data. 2. Find out how much data is available in the ALSA ring buffer. I could then throttle USB interrupts when no data is available in the buffer and try again later. ALSA maintains a read and a write pointer (hw_ptr and appl_ptr) that can be accessed through the snd_pcm_*_avail() functions. However, I'm not sure how to handle proper locking, and I don't understand how runtime->boundary interacts with those functions. I've also heard that there's a free-running mode that will make those functions return bogus values. I'd appreciate help on this. 3. Use another API (dedicated character device, socket, ...) to transfer audio data from userspace to kernelspace. ALSA is way too big for my requirements (2 layers of abstraction, architectured around assumptions that make sense for real sound cards but not for my hardware, ...). On the other hand, it would be handy to use existing ALSA applications to driver the device. I'd appreciate comments regarding the API choice. How do you all expect to push data from a userspace application to a UAC driver on the device side ? If ALSA is *the* way, is one of the above solutions practical or is there a better way ?

[alsa-devel] DMA over run on playback
by Jon Smirl 14 May '09

14 May '09

There's a long thread over on the pulse list about glitch free playback. The glitches they are encountering are caused by CPU scheduling latency. They are trying to fix this by setting HZ up to 1000 and constantly polling the audio DMA queue to keep it 99% full. This doesn't seem like the right solution to me. It is fixing the symptom not the cause. The cause is 200-300ms scheduling latency. The source of that needs to be tracked down and fixed in the kernel. But we have to live with the latencies until they are fixed. The strategy of checking the queue at 1000Hz works but it is very inefficient. The underlying problem is that the buffer ALSA is using is too small on systems with 300ms latency. The buffer is just big enough to cover 300ms so they rapidly check and fill it at 1000Hz to ensure that it is full if the 300ms latency strikes. On my hardware with period interrupts ALSA is only checking the buffer at 8Hz. Since I'm checking appl_ptr I know when DMA over runs the buffers. This allows me to insert silence and I could indicated this condition to ALSA if there was a mechanism for doing so. ALSA could use this over run knowledge to measure scheduling latency and adjust the buffering. But the DMA interface between ALSA and the driver has been fixed at stream creation time. There's no way to dynamically alter it (like window size changes in TCP/IP). With networking you get a list of buffers to send. As you send these buffers you mark them sent. The core is free to hand you buffers straight from user space or do copies and use internal ring buffers. The network driver just gets a list of physical addresses to send. This buffer bookkeeping could occur in snd_pcm_period_elapsed(). A dynamic chaining mechanism allows you to alter the buffering mid-stream. If the driver indication a DMA over run error this tells ALSA that it needs to insert another buffer. After a while these errors will stop and ALSA will have measured worst case CPU scheduling latency. From then on it will know the exact size of buffering needed for the kernel it it running on and it can use this knowledge at stream creation time. Now filling the buffer at 8Hz or lower will work and you don't have to spend the power associated with 1000Hz timer interrupts. -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] WM9712 - Big and little endian format conversion.
by Jon Smirl 14 May '09

I have three areas specifying audio formats. The WM9712 AC97 codec is S16_LE. My DMA hardware is S32_BE. All samples need to be in 32b words even if they are 8,16,24b. The cpu's AC97 system sends the first 20 big endian bits down the AC97 link in the proper order. How can I force the DMA engine setting to override what the codec is saying? Or should the codec be changed to specify all bit lengths and both endians?

[alsa-devel] Avoiding buffer underruns in the hardware interrupt handler
by Laurent Pinchart 14 May '09

14 May '09

Hi everybody. Disclaimer: I'm new with ALSA development and I'm trying to digest the large amount of information I'm overflowed with, so please bear with possibly stupid help requests. I'm writing an ALSA driver for a playback device. Unlike most sound cards, this device uses private memory for its audio buffer. I thus need to manually copy data from the ALSA buffer to the device buffer in the driver. The device audio buffer is quite small, and for this reason I'd rather not use the copy/silence callbacks, but copy data from the ALSA buffer to the device in interrupt. The device might generate interrupts a bit faster than what would be expected from sampling rate, so I need to check in the interrupt handler how much data the ALSA buffer holds. To do so I need to maintain a "hardware pointer" in the driver and to access the "user pointer" on the other side of the buffer. I haven't found a clear API to access that second pointer. What is the best/preferred way to find out how much data the ALSA buffer holds ? I suppose I will need to perform some locking when accessing the "user pointer", I will also appreciate advices regarding which mutex/spinlock I should use for that purpose. Best regards, Laurent Pinchart

[alsa-devel] [PATCH 1/4] pxa2xx-i2s: Proper hw initialization
by Karl Beldan 13 May '09

13 May '09

Make sure we are in a know good state at end of probe : Reset FIFO logic and registers, and make sure REC and RPL functions along with FIFO service are disabled (SACR0_RST enables REC and RPL). Resetting loses current settings so remove reset from stream startup. Now reset occurs only at probe.

[alsa-devel] [PATCH 0/1] Add AIC3106 support.
by Ambrose, Martin 13 May '09

13 May '09

Hello, I patched in support for the AIC3106 codec which is the IC on the DA830 EVM. This patch applies to the ASoC tree: ddc4097b77bbb227851a44287acb2fb8a9896cc1 But it also applies cleanly to the Davinci tree: Unfortunately there are missing pieces needed (e.g. edma/mcasp) for this board on the Davinci tree to test directly. But it passes the smoke test of building and running on the Davinci EVM. -Martin

[alsa-devel] asoundconf removed from alsa-utils?
by Susan Cragin 13 May '09

13 May '09

The message says that asoundconf is not present because alsa-utils is not installed. However, I have just installed the latest. 20090512. And the following alsa-utils work: arecord works, as well as alsamixer and alsactl. I hesitate to even report this, because I'm on karmic with 2.6.30-5-generic kernel, and I know there are bugs, and that I am pre-alpha. So this is FYI -- no response needed or expected. Susan

[alsa-devel] emu10k1 TRAM access ?
by mAdVax 13 May '09

13 May '09

Hello I would like to send some data to a DSP patch. I can use alsa controls (easy) but I need more : TRAM and lookup table. I read many lines of code, but all this is still quite obscure... Here are 3 questions : How can I fill the TRAM ? (from user space) How can I know which TRAM area has been allocated to a given patch ? Do 'lookup tables' work ? Some code samples will be greatly appreciated :) Thanks in advance. Xavier

[alsa-devel] ALSA 1.0.20 PCM Capture Problem (Does not happen on ALSA 1.0.19)
by Robert Vincent Krakora 13 May '09

13 May '09

Hello, I am utilizing an external mic on my machine in conjunction with a VF0560 Live! Cam Optia AF webcam. I am running CentOS 5.3 with the kernel listed below and ALSA 1.0.20. I using the machine to stream video with VLC 9.9 (see further below). VLC spits out the following on the console of my machine whist capturing A/V and serving it up on the network...ALSA 1.0.19 did not exhibit this problem while streaming it did lock up after 20 minutes or so (audio could be heard on the VLC or mplayer client with ALSA 1.0.19...just bits and pieces of audio every now and then with ALSA 1.0.20. V4L is not the culprit here as video streams and can be received without incident if I do not also capture audio. The mic is plugged into the onboard sound on the motherboard. I have not yet tried my USB mic with ALSA 1.0.20, but I will try it later tonight. Any and all help would be greatly appreciate. Thanks in advance.

[alsa-devel] patch to support Samsung NC10 mini notebook
by Chris Pockele 13 May '09

13 May '09

Hello, The attached file is a patch to support the sound hardware in the Samsung NC10 mini notebook. The Samsung NC10 is and Intel Atom-based notebook with Realtek ALC272 HDA codecs. Sound is supported partly in Linux depending on ALSA version, but there were always some issues (wrong mixer behaviour, PC beep always muted, ...). This patch tries to solve most of these issues. I updated the patch so it would work using the alsa-driver-20090509 snapshot from ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/ (originally developed from alsa-driver-20090416 snapshot). Fixes: - mute internal speaker / microphone when plugging in external headphone / microphone - stereo capture from external microphone - separate volume controls for headphone and internal speakers + "Master" for both - "PC Beep" mixer control - "Mic boost" and "External mic boost" controls - ... A few issues remaining: - Recording PCM output does not work yet. It works on the version of Windows that comes with the NC10. - When choosing recording source "Internal Mic" while an external microphone is plugged in, the internal microphone will be used instead of the external one, as it should. However, when plugging in the external microphone after choosing the recording source setting, it WILL override the internal microphone. When replying, please note I am not on list. Regards, Chris http://users.skynet.be/chrisp/linux/

[alsa-devel] pxa2xx-pcm and dma_request
by Robert Jarzmik 13 May '09

13 May '09

Hi Mark and Dimitry, I've been playing for some time with DMA on the PXA series. I was wondering if the behaviour of pxa2xx-pcm is correct. As far as I understand, in an asoc context, the __pxa2xx_pcm_open() is called, while in "arm context", pxa2xx_pcm_open() is called, which calls __pxa2xx_pcm_open(). This was introduced by commit a6d77317678148c973bb0131cc5a3a772f756d23 I think. One main difference is that in "arm context", pxa_dma_request() is called, while in "asoc context", it is not. I'd like one of you to cross-check, as I must admit I'm not following all the impacts of the pcm code split-up. Cheers. -- Robert

[alsa-devel] aplay as a Zombie shows up in systemsupervisor when starting Totem or Totem-xine.
by Kristoffer Grundström 13 May '09

I think I've identified the issue with my sound as aplay being a Zombie everytime I'm starting totem or totem-xine. When restarting ALSA with service alsa restart as root I get what's shown in this link: http://pastebin.mandriva.com/11255 3319 is Pulseaudio. Pulseaudio disappears when closing totem or totem-xine. This problem has to do with my earlier mentioned bugreport in this link: https://qa.mandriva.com/show_bug.cgi?id=49048 Thank you. /Kristoffer

[alsa-devel] storm of emu10k1: unhandled interrupt: 0x00400000

Hi, Martin von Gagern reported a bug in the emu10k1 driver while running 2.6.29: https://bugs.gentoo.org/show_bug.cgi?id=266657 This message is logged seemingly infinitely, to the point where the system became unusable. emu10k1: unhandled interrupt: 0x00400000 This is INTE_ADLIBENABLE. The bug is a one-off and unreproducible, this mail is really just for information only... or would people be happy with this flag being added to the "mask the interrupts that we don't handle" code below the code that prints the "unhandled interrupt" message?

[alsa-devel] [PATCH] control, hw, rawmidi: accept control device node as card identifier when opening
by Lennart Poettering 12 May '09

12 May '09

Heya! Traditionally low-level ALSA devices are opened with device strings like 'hw:CARD' where CARD is either a numeric index or a card name. This patch introduces a third syntax that allows you to specify the file name of the control device node. The purpose for this is to make ALSA a bit more like other Linux devices and allow implementaiton of udev device symlinks similar to how disks are currently handled, with /dev/disk/by-path/xxxx /dev/disk/by-id/xxxx and so on. With this patch this line: aplay -f CD -D hw:/dev/snd/controlC0 < /dev/urandom becomes equivalent to this line: aplay -f CD -D hw:0 < /dev/urandom A more useful example is this: aplay -f CD -D hw:/dev/snd/by-path/pci-0000:00:1a.7-usb-0:2:1.2 (this line requires a a few additional udev rules) This only works for control devices nodes, not for PCM or any other device nodes. Since the control device node is used as 'entry point' when opening PCM devices this is no limitation.

[alsa-devel] Master vs. Front/Rear/LFE/... elements
by Lennart Poettering 12 May '09

12 May '09

Heya! Some cards expose 'Master' volume sliders. Others expose seperate (stereo) sliders for 'Front', 'Rear' and so on. I have trouble dealing with them properly in PulseAudio: First of all, on some cards 'Master' seems not to have any effect on the actual analog output, only 'Front' and friends do. Is this a bug or intended behaviour? Can I assume that 'Master' and 'Front' are always independant? Secondly, I have trouble supporting the 'Front'/'Rear'/'Side'/... elements properly, since they split up the surround channels into seperate elements. Now, this is confusing in many ways, even for "amixer" which will then show channels such as "Rear Front Left" and so on, which obviously make no sense. snd_mixer_selem_has_playback_channel() just returns bogus data for these cases. Why are those elements seperate anyway? Why aren't they combined into a single multi-channel event? Looking at the APIs I get the idea that the problem appears to be that elements can only control all channels the same are all independantly which doesn't really match 1:1 on my multichannel sound cards. However, wouldn't it be possible to use the 'index' value of a selem_id for this? I.e. have a series of controls by the same name but different indexes which would then implement snd_mixer_selem_has_playback_channel() correctly? i.e. foo,0 would do front-left/right, foo,1 would do rear, foo,2 would do lfe, and so? I have no clue how this implemented internally, so not sure how feasible this might be.

[alsa-devel] 2.6.29 Vs 2.6.30
by Harsha, Priya 12 May '09

12 May '09

Hi, I was developing a driver on 2.6.29 and it was playing using aplay properly but when I moved to 2.6.30, same code base is giving me underrun messages. What is the changes with respect to this in 2.6.30? Primarily, why do underrun messages come and how does driver need to handle it? Any clue will be of great help. Thanks, Harsha

[alsa-devel] ALSA for SoC audio support full duplex problem
by jinjin xu 12 May '09

12 May '09

Dear All. I use 2.6.21.5-cfs-v19 on S3C6410(arm),use wm8987 sound card(i2s interface) It is not use in full duplex. I grep and diff the drivers ens1370.c: snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_PLAYBACK, &snd_ensoniq_playback1_ops); snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_CAPTURE, &snd_ensoniq_capture_ops); soc-core.c: if (playback) { snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_PLAYBACK, &soc_pcm_ops); } if (capture) { snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_CAPTURE, &soc_pcm_ops); } ens1370.c use two different fops for playback and record(I test it in Vmware,It can run on full duplex) soc-core.c use the same fops for playback and record It that the problem ? So how to fix it for support full duplex? Thanks!

by Joonyoung Shim 12 May '09

12 May '09

The mixer DAPM is suitable than the mux DAPM for the analog microphone registers(0x05, 0x06) because each bit for path is switchable.

Well, the problem I'm concerned is that the driver can be compiled in even if you have no built-in firmware. And there is no restriction or dependency check in Kconfig, so far. Could you test how the kernel behaves without the built-in firmware? Does it hang or give any critical error? thanks, Takashi

[alsa-devel] Audio blank samples after some seconds of playing
by javier Martin 12 May '09

12 May '09

I have a .wav file which lasts about 2 minutes. I am playing it with aplay. It works fine, but after some seconds of playing, I hear two blanks suddenly. After that, it continues playing fine till the end of the file. I have tried to increment buffer size and period size but I don't see any difference. Possition of blank samples seems to be quite random, but it always happens near the beggining of the file. Can you please give me some tip for debugging this problem or an idea of what more can I try? Thank you.

[alsa-devel] MacbookPro5,1 & hda-analyzer
by Ozan Çağlayan 11 May '09

11 May '09

Hi, I just bought a MacbookPro5,1 and having difficulties with the onboard HDA chipset. * No sound can be heard of it if model= is not set to mbp3: [ 12.009422] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... http://www.alsa-project.org/db/?f=4b2f257e72523bccafd3ace1d3c7044fb5f09ff8 * If model=mbp3 is given, it's possible to get sound from it but with many annoying problems: - You have to switch to 6ch mode for getting sound, doesn't work with 2ch mode, - The sound quality is very very bad, - Once you switch to 6ch mode, - You have to increment the volume of *Line-in* to have hearable sound from *internal speakers*, - You have to increment the volume of *Front* to have hearable sound from *headphones*, - The two controls are not mutually exclusive, you have to mute one of them, if you're using the other. And then I decided to play with hda-analyzer. After a bit of playing, I started to get sound from the board without the model=mbp3. But the mixers are still behaving somewhat strange. Before actually reporting any feedback on what I've switched and did, what do you suggest me to do? Is setting the model= to something, something similar to what I was doing with hda-analyzer? Thanks Ozan Caglayan

[alsa-devel] spdif/iec958 outputs at VT1708S not recognized
by Peter Niemayer 11 May '09

11 May '09

Hi, I recently installed an Asus M4N78 mainboard, that uses a nVidia GeForce 8300 chipset and a VT1708S soundchip. Alas, the code in pci/hda/patch_via.c did not recognize the 3 existing iec958/spdif outputs, and presented only the analog devices. I had to short circuit the pin definition in vt1708S_parse_auto_config() to get the digital outputs to work: spec->multiout.max_channels = spec->multiout.num_dacs * 2; - if (spec->autocfg.dig_out_pin) + // test fails for Asus M4N78 if (spec->autocfg.dig_out_pin) spec->multiout.dig_out_nid = VT1708S_DIGOUT_NID; spec->extra_dig_out_nid = 0x15; The digital sound output works just fine for me with this change, but I guess there should be a cleaner way to make this work? Several people in forums on the InterNet reported similar problems with getting their digital outputs on VT1708S to work under Linux. Regards, Peter Niemayer

[alsa-devel] [PATCH 3/4] pxa2xx-i2s: Cleaner use of the FIFOs
by Karl Beldan 09 May '09

09 May '09

The FIFO logic and the registers are reset at stream startup with SACR0_RST => the sibling function might suffer and the FIFOs might unpleasantly fill up whence the calls to pxa_i2s_wait all over the place.

[alsa-devel] asus xonar DX
by Dmitri Seletski 08 May '09

08 May '09

Hello boys and girls. I have successfully installed asus xonar DX onto PCIE x16 slot on Linux 2.6.28-gentoo-r5 SMP on amd64 architecture. Version of alsa package - alsa-driver1.0.20, alsa firmware 1.0.19. I used alsa package and not kernel modules. Several channels seem to work fine(my speakers are broken, no back channels available, started holy war with creative about it, guess with fiasco with faulty speakers and xfi drivers i am supporter of creative no more, i am not gonna bad mouth them either just yet). So far so good. Microphone works, surround sound works too, I am pretty happy. Thanks for all people who advised me something.

[alsa-devel] Laptop (Samsung Q45) speakers unmute when master channel is unmuted even with headphones connected
by Sam Morris 07 May '09

07 May '09

Since Linux 2.6.28 and through to 2.6.30-rc4, the hda-intel driver has had a bug on my laptop (a Samsung Q45). If I connect my headphones, the laptop's internal speakers are muted--fine. But if I then mute and unmute the master mixer channel, the speakers come back to life, even though the headphones are still connected. Please keep 517241-forwarded(a)bugs.debian.org CC'd in follow-ups. -- Sam Morris https://robots.org.uk/ PGP key id 1024D/5EA01078 3412 EA18 1277 354B 991B C869 B219 7FDB 5EA0 1078

Re: [alsa-devel] [Intel] RE: How to play second stream in linux
by Yang, Brandon 07 May '09

07 May '09

Hi Takashi, Thanks for your guidance. I had added some code to play second stream in HD audio driver. Our PM would like us to upstream the source code. He thinks it would be more convenient for customer if they can download the code from ALSA. Our source code is base on kernel 2.6.24.2 and specific to ALC262. As you know, some of our code is hard-coded for our platform. I don't know whether this code can meet your requirement or not. If it can meet your requirement, please help me to upstream it. Thanks very much. The attached file is the patch file. Best Regards, Brandon

[alsa-devel] audio mixing
by Gabriel Johnson 06 May '09

06 May '09

I am using alsa libs to mix audio alerts in my application. I am using the aplay code as an example. I am playing two audio files, one that is 5sec and one that is a beep, from two different threads. The thread that plays the beep loops and plays it every second. I am playing the two audio files through the same snd_pcm_t handle. When the 5sec audio file finishes I then the pcm gets into an xrun state. Instead of using the same handle for all audio should I just associate one handle per audio file? Is there something else I can do to make the pcm handle more stable when playing multiple audio files?

[alsa-devel] dmix and mmap
by Gabriel Johnson 06 May '09

06 May '09

I am currently working on two issues. First, I am trying to add mmaping support to the pcm driver I am using so that I can use the dmix plugin. My driver is a soc driver for the powerpc mpc5121. The pcm_new function preallocates the dma buffers with the following code: static int mpc512x_pcm_preallocate_dma_buffer(struct snd_pcm *pcm, int stream) { struct snd_pcm_substream *substream = pcm->streams[stream].substream; struct snd_dma_buffer *buf = &substream->dma_buffer; size_t size = mpc512x_pcm_hardware.buffer_bytes_max; buf->dev.type = SNDRV_DMA_TYPE_DEV; buf->dev.dev = pcm->card->dev; buf->private_data = NULL; buf->area = dma_alloc_coherent(pcm->card->dev, size, &buf->addr, GFP_KERNEL); if (!buf->area) return -ENOMEM; buf->bytes = size; return 0; } Given the way the dma buffers are allocated if I just add SNDRV_PCM_INFO_MMAP and SNDRV_PCM_INFO_MMAP_VALID to my snd_pcm_hardware struct with the alsa framework use a generic mmap function or do I still need to implement one? If I need to implement a mmap callback what is the fastest and most simple way to add that support? Second, I need to test dmix with my driver. My codec only supports S16_BE. When I try to use `aplay -Dplug:dmix -f SE16_BE mywave.raw` I get the error `requested or auto-format is not available`. After looking in pcm_direct.c it appears that when I use -Dplug:dmx it ignores -f S16_BE and is defaulting to some format that my codec doesn't support. I don't have a /etc/alsa.conf or ~/.asoundrc file and /proc/asound/modules doesn't exists. Where is aplay getting the default setting for plug:dmix? How can I override those defaults? I am using alsa-lib-1.0.11rc2. Thanks, Gabe

Is there some way to get a call out after a period DMA buffer is filled so that I can add it to the DMA queue? -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] Issues with HP DV4 laptop sound after Ubuntu Jaunty 9.04 upgrade
by Guy Stalnaker 05 May '09

05 May '09

Hello again. I was able to get my internal speakers working for my HP Pavilion Dv4 laptop by following the advice I found in the alsa-devel archives. That advice seems to have worked for quit a few people who found it by a post I made to the Ubuntu Forums. But now, after I have upgraded my Ubuntu from version 8.10 (when sound worked) to version 9.04, sound no longer works correctly. I have some detailed information about the sequencing and the specific error. Attached is an alsa-info.txt output. Here's what I'm seeing (extracts from dmesg/kernel logs): Apr 29 15:13:17 Harlindon kernel: [ 19.937190] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 29 15:13:17 Harlindon kernel: [ 19.937270] HDA Intel 0000:00:14.2: setting latency timer to 64 Apr 30 09:37:09 Harlindon kernel: [ 19.941675] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 30 09:37:09 Harlindon kernel: [ 19.941750] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:06:01 Harlindon kernel: [ 19.852324] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:06:01 Harlindon kernel: [ 19.852398] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:13:43 Harlindon kernel: [ 20.950985] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:13:43 Harlindon kernel: [ 20.951060] HDA Intel 0000:00:14.2: setting latency timer to 64 Commit Log for Fri May 1 16:41:58 2009 [Upgrade to Ubuntu Jaunty 9.04] May 1 17:11:05 Harlindon kernel: [ 20.318416] hda-intel: unable to grab IRQ 0, disabling device May 1 17:11:05 Harlindon kernel: [ 20.318517] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:14:18 Harlindon kernel: [ 22.977762] hda-intel: unable to grab IRQ 0, disabling device May 1 17:14:18 Harlindon kernel: [ 22.977828] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:18:49 Harlindon kernel: [ 21.105013] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 17:18:49 Harlindon kernel: [ 21.105087] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 21:15:14 Harlindon kernel: [ 19.776991] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 21:15:14 Harlindon kernel: [ 19.777893] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:22:01 Harlindon kernel: [ 20.540543] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 09:22:01 Harlindon kernel: [ 20.540619] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:26:04 Harlindon kernel: [ 19.819578] hda-intel: unable to grab IRQ 0, disabling device May 2 09:26:04 Harlindon kernel: [ 19.819677] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 10:37:28 Harlindon kernel: [ 20.175934] hda-intel: unable to grab IRQ 0, disabling device May 2 10:37:28 Harlindon kernel: [ 20.175999] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 13:26:27 Harlindon kernel: [ 20.610591] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 13:26:27 Harlindon kernel: [ 20.610666] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 16:57:23 Harlindon kernel: [ 19.885497] hda-intel: unable to grab IRQ 0, disabling device May 2 16:57:23 Harlindon kernel: [ 19.885575] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 18:20:18 Harlindon kernel: [ 22.605977] hda-intel: unable to grab IRQ 0, disabling device May 2 18:20:18 Harlindon kernel: [ 22.606042] HDA Intel: probe of 0000:00:14.2 failed with error -16 What is damned peculiar is that is has sometimes worked (as you can see above).

[alsa-devel] looking for advice on buying a card
by Dmitri Seletski 05 May '09

05 May '09

Hello Guys I am thinking to buy pci express sound card. Nothing fancy, just something with dolby surround 7.1 and decent sound quality, rather inexpensive, i am not audiophile. I have noticed that there are not that many sound cards out there which have descent support in Linux(unlike many forums claim). I have had MAJOR problems with pci xfi card from creative labs(fatality gamers edition), my buddy still has a lot of problem with it, like major issues with input. No mic - no skype or other voip, you know yourself... I have found source of asus xonar dx(namely ebay), it is not that expensive compared to many other pci express cards out there, still is expensive enough, from alsa matrix it appears to be quite descent. Question is, is it worth buying? Is it painful to get it running?(probably nothing unusual, matter of loading module), does it work fully(does microphone work, does surround sound 7.1 work?)? Is there something better for similar money?(EUR 73 or £65 or $97) Please do not propose incompletely supported cards(while i wouldn't mind submitting issues to mail lists if i come across bugs, i wouldn't want product that doesn't work) I appreciate any comments. Thank you in advance. Dmitri

[alsa-devel] module snd-atiixp issue with suspend/hibernate/resume
by Ryan Dunn 05 May '09

05 May '09

I have a Compaq V2000 laptop with the ATI IXP chipset and make use of the snd-atiixp module. The laptop needs to have the ac97_quirk option set to 7 to enable the mute LED. After setting this option in the /etc/modprobe.d/options.conf file, the mute LED works after a reboot. However, after a resume from suspend or hibernate, the mute LED does not work. The alsa-info.sh script reports that the quirk is still set with 7. At this point a reboot will NOT fix the problem. The only way to fix it is to remove and reinsert the module with modprobe. This is on a fresh Ubuntu 9.04 install. Any ideas? I wasn't sure if this should be reported here or on the kernel list. I saw a similar issue with the ac97_quirk on the kernel list and they were referred here. I'm a software developer, so I'd be willing to try ideas/possible solutions if you have them. Thanks, Ryan

[alsa-devel] [PATCH 1/2] ASoC: TWL4030: Add VDL analog bypass
by Lopez Cruz, Misael 04 May '09

04 May '09

This patch adds voice downlink analog bypass switch. It follows the same approach as in other analog bypass switches. DAC switch is moved from 'DAC Voice' to 'Analog Voice Playback Mixer', that will also allow voice DAC to be powered in digital voice loopback (sidetone).

The problem appears to be related to the autoconfig handling of the line out nids. The current code ends up with something like the following: ALSA sound/pci/hda/hda_codec.c:3833: autoconfig: line_outs=1 (0x17/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3837: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3841: hp_outs=1 (0x21/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3842: mono: mono_out=0x0 ALSA sound/pci/hda/hda_codec.c:3853: inputs: mic=0x18, fmic=0x19, line=0x0, fline=0x0, cd=0x0, aux=0x0 However, NID 0x17 is actually a speaker_out. The code that checks for line_outs in snd_hda_parse_pin_def_config() unsets the speaker_out and uses that NID for a line_out. For whatever reason, this breaks things (no sound output, no headphone out). According to the ALC272 data sheet (the block diagram on page 5), there are actually 2 line_out NIDs; 0x14 and 0x15. The default pin configs for these two NIDs (0x411111f0 for both) have the Port Connectivity field set to AC_JACK_PORT_NONE, so the auto-config skips those NIDs. If I provide an override to a) set Port Connectivity to AC_JACK_PORT_COMPLEX, and b) set Default Device to AC_JACK_LINE_OUT (from AC_JACK_SPEAKER), I get usable audio (speakers work, headphone works, headphone plugging mutes the speaker properly, and even the mic works). The patch which I've used is below. Clearly, this isn't a very nice solution, so the question is: is there a way to provide an override/quirk for pincfgs (I see one for HWDEP, but that's configuration-specific) within the current hda_codec framework for this specific codec/laptop? Alternatively, I can try and figure out what's wrong with the code in the case where line_out_pins[0] is set to the speaker_out_pins[0] (ie, NID 0x17 in this case). I can check the other ALC272 machine tomorrow (the DELL_ZM1) to see if the line_out hack enables it to work without the verb table. diff --git a/sound/pci/hda/hda_codec.c b/sound/pci/hda/hda_codec.c index b91f6ed..5aa7a0c 100644 --- a/sound/pci/hda/hda_codec.c +++ b/sound/pci/hda/hda_codec.c @@ -3644,6 +3644,15 @@ int snd_hda_parse_pin_def_config(struct hda_codec *codec, continue; def_conf = snd_hda_codec_get_pincfg(codec, nid); + snd_printd("nid %x: pincfg def_conf=%x\n", nid, def_conf); + if (codec->vendor_id == 0x10ec0272 && + (nid == 0x14 || nid == 0x15)) { + def_conf &= ~(0x3 << AC_DEFCFG_PORT_CONN_SHIFT); + def_conf &= ~(0xf << AC_DEFCFG_DEVICE_SHIFT); + snd_printd("nid %x: overriding def_conf, now %x\n", nid, + def_conf); + } + if (get_defcfg_connect(def_conf) == AC_JACK_PORT_NONE) continue; loc = get_defcfg_location(def_conf);

[alsa-devel] [PATCH 2/2] ASoC: TWL4030: Add voice digital loopback: sidetone
by Lopez Cruz, Misael 04 May '09

04 May '09

This patch add voice digital loopback (sidetone) to the twl4030 driver. It mixes voice uplink attenuated (by sidetone gain) with voice downlink when the codec is working in option2 (voice/audio mode).

[alsa-devel] Issues with HP DV4 laptop sound after Ubuntu Jaunty 9.04 upgrade
by Guy Stalnaker 03 May '09

03 May '09

Hello again. I was able to get my internal speakers working for my HP Pavilion Dv4 laptop by following the advice I found in the alsa-devel archives. That advice seems to have worked for quit a few people who found it by a post I made to the Ubuntu Forums. But now, after I have upgraded my Ubuntu from version 8.10 (when sound worked) to version 9.04, sound no longer works correctly. I have some detailed information about the sequencing and the specific error. Attached is an alsa-info.txt output. Here's what I'm seeing (extracts from dmesg/kernel logs): Apr 29 15:13:17 Harlindon kernel: [ 19.937190] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 29 15:13:17 Harlindon kernel: [ 19.937270] HDA Intel 0000:00:14.2: setting latency timer to 64 Apr 30 09:37:09 Harlindon kernel: [ 19.941675] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 30 09:37:09 Harlindon kernel: [ 19.941750] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:06:01 Harlindon kernel: [ 19.852324] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:06:01 Harlindon kernel: [ 19.852398] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:13:43 Harlindon kernel: [ 20.950985] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:13:43 Harlindon kernel: [ 20.951060] HDA Intel 0000:00:14.2: setting latency timer to 64 Commit Log for Fri May 1 16:41:58 2009 [Upgrade to Ubuntu Jaunty 9.04] May 1 17:11:05 Harlindon kernel: [ 20.318416] hda-intel: unable to grab IRQ 0, disabling device May 1 17:11:05 Harlindon kernel: [ 20.318517] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:14:18 Harlindon kernel: [ 22.977762] hda-intel: unable to grab IRQ 0, disabling device May 1 17:14:18 Harlindon kernel: [ 22.977828] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:18:49 Harlindon kernel: [ 21.105013] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 17:18:49 Harlindon kernel: [ 21.105087] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 21:15:14 Harlindon kernel: [ 19.776991] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 21:15:14 Harlindon kernel: [ 19.777893] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:22:01 Harlindon kernel: [ 20.540543] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 09:22:01 Harlindon kernel: [ 20.540619] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:26:04 Harlindon kernel: [ 19.819578] hda-intel: unable to grab IRQ 0, disabling device May 2 09:26:04 Harlindon kernel: [ 19.819677] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 10:37:28 Harlindon kernel: [ 20.175934] hda-intel: unable to grab IRQ 0, disabling device May 2 10:37:28 Harlindon kernel: [ 20.175999] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 13:26:27 Harlindon kernel: [ 20.610591] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 13:26:27 Harlindon kernel: [ 20.610666] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 16:57:23 Harlindon kernel: [ 19.885497] hda-intel: unable to grab IRQ 0, disabling device May 2 16:57:23 Harlindon kernel: [ 19.885575] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 18:20:18 Harlindon kernel: [ 22.605977] hda-intel: unable to grab IRQ 0, disabling device May 2 18:20:18 Harlindon kernel: [ 22.606042] HDA Intel: probe of 0000:00:14.2 failed with error -16 What is damned peculiar is that is has sometimes worked (as you can see above).

Re: [alsa-devel] [Alsa-user] looking for advice on buying a card
by Dmitri Seletski 02 May '09

Hi Gary. Well, thank you for the idea, but i somehow not comfortable with it. I have to buy this thing, even if it's inexpensive, i will have to pay good amount of money for delivery. I am looking around 20 euro, not counting price for device itself. Than again, i have to buy new card and pay for delivery there. To make things worse, none xfi sound cards are no longer produced by creative labs and i really don't like idea of second hand sound cards(even though you have to be very skillful to break one of those). So it simply makes sense to pay a bit extra(i was loosing those money with that pcie to pci extentsion and its delivery anyway) but to get that card I was referring before, Asus Xonar DX I know it's supported by alsa, because of this: http://www.alsa-project.org/main/index.php/Matrix:Vendor-Asus I am just double checking, since this specific card is really promising one and i really feel like buying one. But again, i am opened for other options. Thanks a lot for your thoughts. I have kinda got used to USB cards by now myself and all those troubles they cause :) gary wrote: > Having spent an ungodly obscene amount of time trying to get two > different USB audio cards to work in 64 bit opensuse, I suggest not > trying to be a pioneer.

[alsa-devel] New codec for STAC9766 used on Efika
by Jon Smirl 02 May '09

02 May '09

Could you please review this new STAC9766 codec implementation. Some of the controls aren't where they need to be. For example the mutes on the mixer inputs. I'm not sure where they are supposed to go. How should SPDIF support work? The hardware supports simultaneous use of analog and SPDIF. Do I want one DAI or two? If I have two DAI then ALSA needs to interleave the samples into a single DMA stream. So if one stream isn't active it needs to be filled with silence. Other options... A single DAI with a switch A single DAI with the same output stream on both analog and SPDIF. I've tried to add the DAPM routes. I don't know of anyone using this chip on a low power design. Datasheet is here: http://www.idt.com/products/getDoc.cfm?docID=13134007 I get a few errors from the current config: Failed to add route All Analog Mixer->Pop Bypass Mux dapm: STAC9766: configuring unknown pin OUT3 dapm: STAC9766: configuring unknown pin MONOOUT Failed to add route HPOUTL->Headphone Jack dapm: STAC9766: configuring unknown pin OUT3 dapm: STAC9766: configuring unknown pin MONOOUT Failed to add route HPOUTL->Headphone Jack /* * stac9766.c -- ALSA Soc STAC9766 codec support * * Copyright 2008 Jon Smirl, Digispeaker * Author: Jon Smirl <jonsmirl(a)gmail.com> * * This program is free software;

[alsa-devel] [PATCH] ASoC: TWL4030: Disable DACs in analog loopback
by Lopez Cruz, Misael 30 Apr '09

30 Apr '09

In analog loopback mode, DACs should not be enabled. For that reason, DAC widgets (DAC Right1, DAC Left1, DAC Right2, DAC Left2) will power DACs only during playback. Analog loopback requires to set a master enable bit when any of the analog bypass switches are enabled.

[alsa-devel] [RFC PATCH 3/5] pxa: clean up the legacy SSP API
by Eric Miao 30 Apr '09

30 Apr '09

Actually, due to the number of possible SSP configurations, it's quite a difficult job to maintain an API that can be well re-used. The guideline here is to keep only a list of SSP devices and their basic information, and it's up to the user driver (like SPI or Audio SSP) to configure the SSP in a desired way. Now that the legacy 'struct ssp_dev' based APIs are removed, and only the functions below are kept, modified a little bit to make them aware of the new 'struct ssp_device': ssp_enable() ssp_disable() ssp_save_state() ssp_restore_state() And finally, ssp_{save,restore}_state() can be merged into the suspend() and resume() interface of the SSP's platform_driver, thus saving the user driver from doing some similar things in common.

[alsa-devel] 6-channel output and i2s
by Jon Smirl 29 Apr '09

29 Apr '09

My hardware was has three stereo i2s lines. These three lines are all tied to the same external clock so they are synchronized. Because there are three i2s lines, each with it's own DMA queue and FIFO, I need three independent output buffers. What is the correct way to set this up in ALSA? -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] Detect when sound card is in use
by Claus Ilginnis 29 Apr '09

29 Apr '09

Hi everyone, I have a problem and I dont't know where to ask my questions anymore, so I hope this mailing list can help me make progress with my problem.... I have a speaker set connected to an USB-Power-Plug (by which I can turn the speakers on and off ) Now I want to detect, when the soundcard is in use and when not. (to turn the speakers on when needed...) (I am a C++ programmer so I can mess some things up) So my question is: Which way is best to detect wheather my sound card is in use or not ? Is there a general overview/documentation of the sound kernel modules which describes the general relationship between them ? What would you do ? PLEASE help ! - Mit freundlichen Grüßen / Best regards Claus Ilginnis

[alsa-devel] Getting the correct capture mixer
by Ludovico Cavedon 29 Apr '09

29 Apr '09

Hi, I am working on fixing some audio related bugs of a VoIP application (qutecom) which, like most VoIP applications, allows the user to change the playback and recording volume. For playback volume I am opening the "Master" mixer element. However I am not able to figure out how the application should get the correct mixer for playback. Is there any rule? For example, my sound card has two capture volumes, one "Int Mic" and one "Ext Mic". I guess I should choose on the basis of what is the user-selected mic. In fact there are also two mutually exclusive switches "IntMic" and "ExtMic". But how should the application understand that? Here part of the output of amixer, my sound card is "Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]" ---------------------------- Simple mixer control 'Ext Mic',0 Capabilities: pvolume cvolume pswitch cswitch Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 20 Capture 0 - 23 Front Left: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Front Right: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Simple mixer control 'ExtMic',0 Capabilities: cswitch cswitch-joined cswitch-exclusive Capture exclusive group: 0 Capture channels: Mono Mono: Capture [off] Simple mixer control 'Int Mic',0 Capabilities: pvolume cvolume pswitch cswitch Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 20 Capture 0 - 23 Front Left: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Front Right: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Simple mixer control 'IntMic',0 Capabilities: cswitch cswitch-joined cswitch-exclusive Capture exclusive group: 0 Capture channels: Mono Mono: Capture [on] ------------------------ As an aside, it looks like that the capture volume has no effect, as well all as the cswitches and pswitches of "Int Mic" and "Ext Mic". Thanks, Ludovico

[alsa-devel] No sound on Acer Aspire 6935G
by Karthik Ramgopal 29 Apr '09

29 Apr '09

Hi, I am using Ubuntu 9.04 Jaunty Jackalope with the latest alsa-driver snapshot provided by Takashi. The sound system does not work without a hda-verb command manually executed every time the system starts up. The command I execute is: hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2 If I do this I get audio out. But my internal mic does not work and nor does jack sensing. When I insert a device into the headphone jack the speakers do not get muted and there is also no sound from the headphones themselves. Even an external mic/line-in device does not work. I have attached the output of alsa-info.sh here.. Please go through it and try to solve the problem. Thanks and Regards, Karthik

[alsa-devel] File SUPPORTED_KERNELS should be updated
by Susan Cragin 28 Apr '09

28 Apr '09

The following is the entire text of that file. ------------------------------------------------------------------------ The alsa-drivers in this package are designed for the following kernels: - Vanilla 2.6.25 or earlier - Vanilla 2.4.31 or earlier - Vanilla 2.2.26 or earlier It's not guaranteed that they work with any newer version than above or modified kernels by distributors. ----------------------------------------------------------------------- Isn't the information obsolete? Aren't the new alsa-drivers in fact destined for 2.6.28 and 2.6.29? Or am I missing something? Susan

I guess you thought that i > would be using the SE model. No, I just thought you are using a model that isn't listed in the ca0106 driver's white list, no matter which one. Createive tends to ship quite lots of variants with different SSIDs although many are compatible. Takashi

[alsa-devel] Benq S32 headphones detection
by Aleh 28 Apr '09

28 Apr '09

Hi, I had a problem with muting speakers when headphones are plugged-in on my Benq S32B. So I added proper board configuration to sound/pci/hda/patch_realtek.c and now it works. I wonder if anyone has similar hardware (S-series Benq laptop) to test the patch (attached) if you find it useful.

Mark the mpc5200 i2s driver BROKEN and lay out a foundation for fixing it. Separate out the mpc5200 core DMA routines from mpc5200_psc_i2s.c into a standalone mpc5200_dma.c.

[alsa-devel] [RFC] SoC WM8940 Driver
by Jonathan Cameron 27 Apr '09

27 Apr '09

From: Jonathan Cameron <jic23(a)cam.ac.uk> Initial support for the WM8940 Mono Codec with speaker driver --- This is my first foray into the world of alsa and aSoC, so I thought I'd make an initial posting of this driver before getting bogged down in testing every last feature works. The board I have has it wired up to i2c limiting options for interface testing and I've currently only tested it as a slave to a pxa271 using i2s. Board is an xbow Imote 2. I will hopefully be able to test a few other interface combinations. All comments welcomed!

[alsa-devel] Creative E-MU 0404 PCI
by A. K. 27 Apr '09

27 Apr '09

Hi all, I'm using EMU 0404 PCI card with Linux (emu10k1), and, AFAIK, not all of this card's features are currently supported. I'd appreciate if you could give me some information about this. Also, I've got troubles with sound recording (playback works quite well). Amixer shows lots of parameters - does anybody know how to configure them right for recording sound ? Thanks for your help. -Jack

[alsa-devel] device underruns
by Daniel Mack 27 Apr '09

27 Apr '09

Hello, I'm currently stress-testing my snd-usb-caiaq driver under several environments and happen to see a number of such messages echoed once in a while at the start of aplay (1.0.16): underrun!!! (at least 1558380812.470 ms long) underrun!!! (at least 1558380818.673 ms long) underrun!!! (at least 1558380812.465 ms long) Also, pulseaudio (0.9.14) keeps complaining with the following message all over the place: E: module-alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Most likely this is an ALSA driver bug. Please report this issue to the PulseAudio developers. What puzzles me a bit is that I don't really know where and how the driver could confuse the core so badly. All it reports is a valid pointer to the current head in each substream. Is there anything else it could provide for tighter syncing? Any hint how to debug this? Or maybe it's not a bug in this specific driver but in the core somewhere? Thanks, Daniel

[alsa-devel] Problem bringing up new alsa driver

My new ALSA driver is playing the first three samples in a loop. It's not progressing forward in the wav file. It's behaving like I'm not calling snd_pcm_period_elapsed() but I have a printk() in it so I'm sure it is being called.

[alsa-devel] Breakage in pcm_lib.c
by Jon Smirl 26 Apr '09

26 Apr '09

These recent commits to pcm_lib.c have fundamentally changed the way snd_pcm_update_hw_ptr_interrupt() works. They have introduced a requirement that snd_pcm_ops.pointer function be able to report the current position of the DMA transfer while the transfer is in progress. The chip I'm working, PowerPC mpc5200, can't do that. There is no access to the internal registers of the DMA engine. On the mpc5200 snd_pcm_ops.pointer always returns the beginning address of the DMA buffer. These checks break audio on the mpc5200 by trying to fix up the pointers when they are actually correct. These checks can probably be modified to take this hardware limitation into account. To simulate our problem on your desktop machine, modify snd_pcm_ops.pointer in your HDA driver to return the front of the DMA buffer instead of the current position inside the buffer. commit bbf6ad1399e9516b0a95de3ad58ffbaed670e4cc Author: Jaroslav Kysela <perex(a)perex.cz> Date: Fri Apr 10 12:28:58 2009 +0200 [ALSA] pcm-midlevel: Add more strict buffer position checks based on jiffies Some drivers like Intel8x0 or Intel HDA are broken for some hardware variants. This patch adds more strict buffer position checks based on jiffies when internal hw_ptr is updated. Enable xrun_debug to see mangling of wrong positions. As a side effect, the hw_ptr interrupt update routine might do slightly better job when many interrupts are lost.

The problem I had with snd_pcm_writen by the way has to do somehow with using a chroot environment; everything works when directly booting into the uclibc / salsa system. For it to work I need to add "irqpoll" to the kernel boot options. Without this, the card does not start playing (though no error messages from salsa) and after a few seconds the kernel tells me to add irqpoll to the boot options. On a glibc / alsa based system everything works fine without this option as it does with a c-media card with salsa. What does it do and why is it needed with the hdsp 9632 on a system with salsa? Thanks Maarten

[alsa-devel] Getting the correct capture mixer
by Ludovico Cavedon 26 Apr '09

26 Apr '09

Hi, I am working on fixing some audio related bugs of a VoIP application (qutecom) which, like most VoIP applications, allows the user to change the playback and recording volume. For playback volume I am opening the "Master" mixer element. However I am not able to figure out how the application should get the correct mixer for playback. Is there any rule? For example, my sound card has two capture volumes, one "Int Mic" and one "Ext Mic". I guess I should choose on the basis of what is the user-selected mic. In fact there are also two mutually exclusive switches "IntMic" and "ExtMic". But how should the application understand that? Here part of the output of amixer, my sound card is "Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]" ---------------------------- Simple mixer control 'Ext Mic',0 Capabilities: pvolume cvolume pswitch cswitch Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 20 Capture 0 - 23 Front Left: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Front Right: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Simple mixer control 'ExtMic',0 Capabilities: cswitch cswitch-joined cswitch-exclusive Capture exclusive group: 0 Capture channels: Mono Mono: Capture [off] Simple mixer control 'Int Mic',0 Capabilities: pvolume cvolume pswitch cswitch Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 20 Capture 0 - 23 Front Left: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Front Right: Playback 0 [0%] [-30.00dB] [off] Capture 0 [0%] [0.00dB] [off] Simple mixer control 'IntMic',0 Capabilities: cswitch cswitch-joined cswitch-exclusive Capture exclusive group: 0 Capture channels: Mono Mono: Capture [on] ------------------------ As an aside, it looks like that the capture volume has no effect, as well all as the cswitches and pswitches of "Int Mic" and "Ext Mic". Thanks, Ludovico

[alsa-devel] .pointer return value
by Harsha, Priya 25 Apr '09

25 Apr '09

Hi, Can anyone educate me on what value should be returned to .pointer function? Should I be passing the number of frames played till that point from the time stream started or thnumber of frames played such that the bytes is within the buf_size? And if I am using, snd_pcm_indirect_playback_pointer, what should be my input to it? Should I be passing the number of bytes played till that point from the time stream started or the number of bytes within buf_size? Thanks, Harsha

I do think salsa lib could return a more relevant error than "operation not permitted" and I'll see if I can come up with something for that. Right now though I am trying to figure out what snd_pcm_writen needs for its second parameter, void** bufs. I get the error "bad address" when passing in an array of pointers to a malloc-ed space big enough to hold a channels' worth of data. Sorry if I am missing obvious documentation about this, but what should I pass for this parameter? Regards Maarten

Hi all, As i am working on alsa for minimal PCM playback (8khz,mono,16 bit pcm file). When i tried to allocate 1k buffer and send through snd_pcm_writei() call it doesn't play perfect and skips are there in between. If we keep on increasing in allocating the buffer for 31 kb then it could play the buffers randomly.

[alsa-devel] salsa error message setting hwparams
by maarten van es 24 Apr '09

24 Apr '09

Hi everyone, I am running out of ideas of why I am getting the error "operation not permitted" when I try setting hw parameters with one of my audio cards. I have a custom linux system based on uclibc with salsa for audio and use the default device for playback. This sytem works fine on a via C7 based pc with via audio. When I try an exact copy of the system on an athlon64 based system with a HDPS9632 I get this error message. The card works fine with other linux systems. I tested several (recent) kernels with my system, all the same result. Any ideas why I might be getting this message? Maarten

[alsa-devel] trouble with alsa, wolfson, and TI OMAP35xx McBSP
by twebb 23 Apr '09

23 Apr '09

I'm having difficulties getting a Wolfson codec running on McBSP1 of an OMAP 35xx. Here are the particulars: 1) Using Linux kernel 2.6.27-omap1, with an ALSA sound driver ported from a Wolfson supplied source tree labeled 2.6.29 (“dev” branch) 2) Using the TI OMAP3530 SOC married to a Wolfson WM8978 codec via McBSP1. I2C control, I2S pcm data. 3) We are running the codec digital block at 1.8V and the analog block at 3.3V 4) The WM8978 codec is synthesizing FCLK and BCLK, codec is the master. McBsp is the slave. 5) FCLK=44.1KHz, BCLK= 32 * FCLK, MCLK = 13Mhz 6) Framing is I2S stereo, 16 bit word I'm seeing two main problems: Problem 1: The WM8978 sample rate PLL does not seem to be stable while DCVDD = DBVDD = 1.8V. FCLK mean = 44.5KHz and jittering. Increasing DCVDD and DBVDD voltage above 2V increases PLL stability. We have a workaround for this for now. Problem 2: Test tone is being presented by the user application, providing a 1Khz tone sampled at 44.1Khz. The data are S16_LE, right channel only. Left channel is quiet. The data seems to slip back and forth from left to right channel. This is reproducable and verified with a scope trace. Anybody have any ideas what might be going wrong here? Traces for codec reg dump and mcbsp are attached. Thanks, twebb

[alsa-devel] [PATCH 0/3] ASoC: 4 channel support for twl4030 and omap-mcbsp - Try2
by Peter Ujfalusi 23 Apr '09

23 Apr '09

Hello, This series adds support for 4 channel DSP mode (A or B) to OMAP McBSP and also to the twl4030 codec driver. As an example the Beagle board file is modified to be able to use 4 channel mode. The change in twl4030 is made in a way, that it will not enable the 4 channel mode when the codec is in OPTION2 mode. Since some of the bits in the OPTION register are shared and have different effect in OPTION1 and OPTION2 modes, an extra care is taken to prevent unvanted modification to the register. Note: The series is on top of Mark's tree in regard of the twl4030 codec, so it is on top of the 'ASoC: TWL4030: Add VDL path support' from Joonyoung Shim. --- Peter Ujfalusi (2): ASoC: OMAP: Add 4 channel support to mcbsp ASoC: TWL4030: Add 4 channel TDM support Ujfalusi Peter (Nokia-D/Tampere) (1): ASoC: Beagle: Add support for 4 channel mode sound/soc/codecs/twl4030.c | 52 ++++++++++++++++++++++++++++++++++++++++- sound/soc/codecs/twl4030.h | 11 +++++++++ sound/soc/omap/omap-mcbsp.c | 5 ++- sound/soc/omap/omap3beagle.c | 26 ++++++++++++++------ 4 files changed, 82 insertions(+), 12 deletions(-)

[alsa-devel] [RFC PATCH 5/5] ASoC: simplify the SSP DMA parameters settings by run-time generation
by Eric Miao 23 Apr '09

23 Apr '09

The SSP DMA parameters can actually be easily generated at run-time since they are almost similar except for the FIFO width and direction. Another benefit is the re-use of information from 'struct ssp_device', like SSDR physical FIFO address and DRCMR register index for both directions.

[alsa-devel] AD1981B SoundMax
by Daniel Vogel 23 Apr '09

23 Apr '09

Hello Developers, sorry if this question is off topic on this list, but I don't know where else to send the question to. I'm currently developing an audio-application on an ARM board that is equipped with an AD1981B SoundMax chip. Everything works well except the build-in equalizer. Since it is impossible to get usable technical information from Analog-Device my last hope is to find someone on this list who has some experience with the chip in question. My problem started with the datasheet not telling the format of the fixed point numbers for biquad coefficients. It only states that they are 16 bit numbers with 16 bit resolution... Then, when I use an estimated value for a0 that is unequal from zero and all other coefficients are zero, in theory I should hear some sound when I play a PCM file (44.1kHz / 16Bit) . But there is only silence on the output when the equalizer is not muted. Is there something else I have to set up to make the equalizer output pass through? Looking forward for answers. ;-) Thanks in advance! Daniel GO Engineering GmbH - Stolzenbergstr. 13/IV - 76532 Baden-Baden Geschäftsführer: Helmut Gerstner, Dipl.-Ing. (FH) Ralf Wörner, Dipl.-Ing.

[alsa-devel] [RFC PATCH 0/5] PXA SSP code cleanup
by Eric Miao 23 Apr '09

23 Apr '09

Remove legacy SSP API by deprecating the only user now - corgi_ts.c, (which could be now well substituted by ads7846 after the sync patch) sound/soc/pxa/pxa-ssp.c is modified and simplified a bit. I guess sound/soc/pxa/pxa-ssp.c will still have to undergo the changes as ASoCv2 progress, hopefully that should be a little bit easier now. -- Cheers - eric

[PATCH] ASoC: simplify the SSP DMA parameters settings by
by Eric Miao 23 Apr '09

23 Apr '09

run-time generation The SSP DMA parameters can actually be easily generated at run-time since they are almost similar except for the FIFO width and direction. Another benefit is the re-use of information from 'struct ssp_device', like SSDR physical FIFO address and DRCMR register index for both directions.

[PATCH] ASoC: simplify the SSP DMA parameters settings by
by Eric Miao 23 Apr '09

23 Apr '09

run-time generation The SSP DMA parameters can actually be easily generated at run-time since they are almost similar except for the FIFO width and direction. Another benefit is the re-use of information from 'struct ssp_device', like SSDR physical FIFO address and DRCMR register index for both directions. In addition, the name of the DMA parameter has been changed to something like: "SSP3 PCM 16-bit out" or "SSP3 PCM 32-bit in" instead of the original "Stereo" and "Mono". This is more consistent with the code.

[alsa-devel] inserting operations while in rate conversion
by Maris 22 Apr '09

22 Apr '09

I'm running uClinux with ALSA in an Analog Devices' Blackfin CPU environment. Actually I'm checking possibilities in doing special things while ALSA is going to do automatic rate conversion. Specific description: ADC is sampled with 32 or 64 ksps rate. The corresponding hardware driver is specified to operate at one of these rates (which I'll specify later). The application reads the ADC input stream at the output end of the ALSA processing as a stream with a rate of 8 ksps. I need some information about inside details of ALSA's automatic rate conversion (pointers to appropriate information would be helpful). What I want to do: insert a digital anti-aliasing filter algorithm which limits the effective bandwidth of the ADC stream to 4 kHz prior to actually have the rate converted. Of course, I could also add the filter algorithm in the hardware device driver - at the cost of not inherently being available as a hardware independent algorithm. Some detail info: - ADC = AD73311 (speech codec). Basic drivers that allow e.g. arecord & aplay are available. - CPU: convergent DSP/microcontroller core @ 500 MHz and fixed point processing. Thanks for attention. BTW: this is my first dig into ALSA details... Rob Code snippet: (currently only one rate is defined as a correspondence to the hardware driver rate) #define AD73311_RATES (SNDRV_PCM_RATE_8000 | \ SNDRV_PCM_RATE_16000 | \ SNDRV_PCM_RATE_32000 | \ SNDRV_PCM_RATE_64000) struct snd_soc_dai ad73311_dai = { .name = "AD73311", .playback = { .stream_name = "Playback", .channels_min = 1, .channels_max = 1, .rates = SNDRV_PCM_RATE_32000, .formats = SNDRV_PCM_FMTBIT_S16_LE, }, .capture = { .stream_name = "Capture", .channels_min = 1, .channels_max = 1, .rates = SNDRV_PCM_RATE_32000, .formats = SNDRV_PCM_FMTBIT_S16_LE, }, }; EXPORT_SYMBOL_GPL(ad73311_dai);

[alsa-devel] bug in salsa async handler + patch
by maarten van es 22 Apr '09

22 Apr '09

Hi, I couldn't find where or how to submit patches for salsa, so here goes. This patch resolves random program crashes when using libsalsa with an async handler: snd_async_del_handler does not correctly maintain its list of async handlers. This patch is for salsa-lib-0.0.21, the latest stable version. change src/async.c, line 118 async_list = h; to src/async.c, line 118 async_list = h->next; Maarten

It's already in sound git tree which I'll send a pull request soon later. The relevant commit contains Cc to stable(a)kernel.org, so that it can be handled easily (automatically?)). thanks, Takashi

[alsa-devel] iMac 9,1 patch work
by Micah Bucy 22 Apr '09

22 Apr '09

I¹m working on a patch for the iMac 9,1 and have the output working. Input is giving me problems. The particular setup is using patch_realtek.c from hda. I noticed that the built-in microphone works if it uses alc883 with model=auto specified. I¹m just not sure what the relevant code is that alc883_auto is using for capture. Any pointers would be helpful. -Micah

[alsa-devel] Asterisk 1.4.17 and alsa 1.0.19 dmix plugin problem.
by Nicola Mfb 21 Apr '09

21 Apr '09

Hi! I'm sorry if this is an old issue but I did not found help in archives/alsaweb/google and I'm new to alsa, so this report is what I guessed reading sources and compiling test apps for about 2 days, and the following assumptions may be completely wrong. Asterisk has an alsa channel that works fine when using plughw:0,0 both for read and for writing, but if use plug:dmix/plug:dsnoop or default with a dmix/dsnoop wrapper in /etc/asound.conf it does not emit any sound. It uses select on poll fd descriptor to know if the pcm is ready to be sent output samples. The select will never return as it seems the dmix plugin is not able to signal when is ready. I noted that using snd_pcm_wait works well but cannot be used in asterisk as it needs to select on two fd. I guess that snd_pcm_wait with dmix check the shared memory and not the fd descriptor. So should poll/select be avoided completely in applications (as they does not know if the default pcm is a dmix) and asterisk alsa channel be rewritten or is there a workaround? Best Regards Nicola

[alsa-devel] Getting M-Audio JamLab simple controls to work
by Greg Erwin 21 Apr '09

21 Apr '09

I have an M-Audio JamLab usb audio interface. Long story short, it works for the most part, but trying to use the simple controls via amixer or alsamixer don't work. I've filed a bug report about it a little while back that has quite a bit of information in it: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4415 Anyway, I feel like it would't take a whole lot to get working (I hope), but the thing is, I bet very few people actually have one. I know a little bit of C, and will be glad to help as much as I can.

[alsa-devel] PS3 Eye Microphone support
by Mihai Tanasescu 21 Apr '09

21 Apr '09

Hello guys, I don't know if this is the proper list to address the question but here it goes and sorry if I'm wrong. I wanted to ask if there is any support for the Playstation3 Eye USB Camera Microphone provided by alsa at the moment or if there are plans to support it. Currently from what I could figure out: root@Mihai:~# cat /proc/asound/cards 0 [Audigy ]: Audigy - Audigy 1 [SB0090] Audigy 1 [SB0090] (rev.3, serial:0x531102) at 0xb880, irq 23 1 [CameraB304061 ]: USB-Audio - USB Camera-B3.04.06.1 OmniVision Technologies, Inc. USB Camera-B3.04.06.1 at usb-0000:00:1d.7-5.1, hi the Microphone Camera is seen there. I successfully recorded something using Audacity and the OSS driver that was reported in the recording options. What I can't do is control the sound levels via the gnome volume control applet (which uses alsactl store and restore). Also, alsamixer won't work. root@Mihai:~# alsactl store alsactl: get_control:262: Cannot read control '2,0,0,Mic Capture Volume,0': Invalid argument root@Mihai:~# alsamixer -c 1 alsamixer: function snd_mixer_load failed: Invalid argument Cheers, Mihai

[alsa-devel] vi-like key bindings for alsamixer

Hello List, I realized that 'j' and 'k' are not used nor reserved for future use with alsamixer. So I decided to use them as aliases for 'up' and 'down'. Is this deemed suitable for the masses? Cheers, Simon Hengel
