As I've never looked at the orion family in details, I assumed this is right and I've changed the naming accordingly. I can change again but it would be nice to have an agreement here. Who's/what's right ? orion can or can not have i2s audio ? Arnaud

[alsa-devel] [PATCH 0/7] ASoC: TWL4030: put the codec to off when not active
by Peter Ujfalusi 26 May '10

26 May '10

Hello, The following series at the end will let the twl4030 codec to use BIAS_OFF instead of BIAS_STANDBY. The difference in power consumption is about 0.5mA. To achieve this: - The regcache has been reseted to codec default - The codec initialization has been optimized, it is no longer writes all 73 registers at startup, but only modifies few selected one. - The power related code has been cleaned up, and optimized - Support added for machine drivers to select the offset cancellation path - debug support for checking the codec default registers (machine drivers can ask for checking, but shall be disabled in production). I guess that's it. The driver has been tested on a custom board with twl5031. It passed all of our internal test cases covering much of the codec features. --- Peter Ujfalusi (7): ASoC: TWL4030: Revisit codec defaults ASoC: TWL4030: Remove wrapper for power down ASoC: TWL4030: Make offset cancellation path configurable ASoC: TWL4030: Optimize the power up sequence ASoC: TWL4030: Helper to check chip default registers ASoC: TWL4030: Correct the ARXR2_APGA_CTL chip default ASoC: TWL4030: Use BIAS_OFF instead of BIAS_STANDBY, when not in use sound/soc/codecs/twl4030.c | 286 ++++++++++++++++++++++++-------------------- sound/soc/codecs/twl4030.h | 2 + 2 files changed, 157 insertions(+), 131 deletions(-)

[alsa-devel] [PATCH]alsa:patch_realtek.c iMac9,1 sound fixes.
by Justin P. Mattock 25 May '10

25 May '10

What seemed to be a simple little task of getting the microphone to work, ended up becoming a bigger task than I had set out. (oh-well, good learning experience). Anyways below you will find an updated patch to the iMac9,1 machine which fixes some issues that I found.(keep in mind this is still a work in progress). First issue: With the original patch, I've noticed by unmuting the mic (and even having it muted), there is a distorted("Noise") coming from the internal speakers, even when the headphones are plugged in. What my finding's revealed is: /* Mic (rear) pin: input vref at 80% */ {0x18, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_VREF80}, {0x18, AC_VERB_SET_AMP_GAIN_MUTE, AMP_OUT_MUTE}, _From the original patch. Looking at codec#0 0x18/0x1a is listed as: Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x00 0x00] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x90100141: [Fixed] Speaker at Int N/A Conn = Unknown, Color = Unknown DefAssociation = 0x4, Sequence = 0x1 Misc = NO_PRESENCE Pin-ctls: 0x41: OUT VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c* 0x0d 0x0e 0x0f 0x26 seems this Node is listed as: [Fixed] Speaker while 0x15 Node 0x15 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x80 0x80] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x018b3020: [Jack] Line In at Ext Rear Conn = Comb, Color = Blue DefAssociation = 0x2, Sequence = 0x0 Pin-ctls: 0x01: VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c 0x0d* 0x0e 0x0f 0x26 is [Jack] Line In at Ext Rear. (looking at the other apple products as examples I came up with the fix below). Second issue: alc885_mbp_4ch_modes The original patch does a good job with the HP pin automute function, but from what I noticed is I would have to manually change the channel form 2 to 4 after plugging the headphones in. And not to mention having odd moments to where I was jamming out with the headphones on, then later realized I had sound blasting out of the speakers as well. My findings revealed that changing alc885_mbp_4ch_modes to alc885_mba21_ch_modes and setting - spec->autocfg.speaker_pins[0] = 0x15; + spec->autocfg.speaker_pins[0] = 0x18; gets the automute function when the headphones plugged in working flawlessly(and the no need to manually change the channel number afterwards). Third issue: alc885_imac91_mixer There probably doesnt need to be anything changed with this (esspecially if your one to like lots of sliders),but my findings revealed that mac osx only has a master on the top right, another switch on itunes, and then a slider for the mic. So the changes I did below try and mimic osx as much as possible (only thing I had an issue with is just having one mute switch on the master, instead of having two(still investigating)). fourth issue: alc882_capture_source I endeded up creating alc889A_imac91_capture_source() only because looking at alc882_capture_source I see that the mic is set to 0x1 while this works, I also noticed that adding 0x1 and 0x01 and testing that 0x1 somehow stops working, and 0x01 works(so I figured 0x01 was more of the alpha of the numbers(still need to figure out where that valuse is)). In any case the microphone does work with the original, and with the below patch, but both still record not as clean(lots of "Noise", which I would like to look into too). Note: using alsamixer -Va reveals the capture switches. Overall the original patch is good, the below patch does (hopefully)address some issues, if it's too much of a change I can go back, and just adjust the verb pins on the original and just call it that..(main thing over here is I don't have the "Noise" coming out of the speakers(and music sounds good)... cheers..

[alsa-devel] Type safe Haskell interface to ALSA sequencer
by Henning Thielemann 25 May '10

25 May '10

Dear ALSA developers, I read the ALSA-Sequencer-API-Doxygen documentation, various ALSA-MIDI-How-Tos and their examples and succeeded to work with ALSA sequencers in Haskell. However, I'm still uncertain about the meaning of the system components and how they interact. It is extensively documented, what works, but not, what does not work. Whenever I do a mistake, ALSA leaves me with an unspecific "operation not permitted" or "invalid argument" error code. Thus I try to encode conditions in Haskell types. For instance once I got an "Invalid argument" error code and only after some investigation, I found that I opened the sequencer in Output mode but later called event_input. (Actually I only wanted to output something, but used event_input for synchronization using Echo events. Unfortunately the intention of Echo messages is even not explained in the Doxygen stuff.) In order to prevent another occurrence of this problem, I defined distinct Haskell types for sequencers depending on the input mode. Now, event_input is only allowed on sequencers that were opened in Output or Duplex mode. However I wondered, why I could create writeable ports in a output-only sequencer. Does this make sense? Would it be reasonable to forbid writeable ports in output sequencers and readable ports in input sequencers by Haskell types? Is there a difference between cap_read|cap_write and cap_duplex? I also wondered why there can be several ports in one sequencer, since multiple clients can connect to one port, and event_input and event_output have no port argument. Further I wondered why queues are not bound to a specific port. Can queues be shared amongst ports? Is it sensible to have multiple queues in one sequencer? Why has sync_output_queue no queue argument? The more I think about it, it seems to me that a port is more an identifier, a part of an address, than a mailbox. I could use ports as tags, that tell which part of an application to control. A queue looks like a mail company and I can use the same sender and receiver addresses across different companies. If this is true, then I think it would be worth to mention this in the API documentation. In another example I called sync_output_queue in order to wait for all events being sent, but it aborted with "Operation not permitted", whereas I have seen example code where it works. What are the preconditions to calling sync_output_queue? I really like to see a picture of how sequencers, clients, ports, port_infos, queues, timers, events are related.

[alsa-devel] [PATCH 1/1] ALSA: usb-audio: add support for Akai MPD16
by Krzysztof Foltman 25 May '10

25 May '10

The decoding/encoding is based on own reverse-engineering. Both control and data ports are handled. Writing to control port supports SysEx events only, as this is the only type of messages that MPD16 recognizes.

[alsa-devel] MMAP in ALSA
by Varadarajan, Srikanth 25 May '10

25 May '10

Hi All, I am new to the list and ALSA. For the hardware I am working with, we expose it to ALSA as one card capable of playing one PCM stream. If we have one application using the hardware through ALSA, other applications are unable to get access to it. So, we want to have PulseAudio on top and use the pulse virtual device to render audio through ALSA. Is this a recommended way of having multiple applications access one audio HW simultaneously? Is there any other way of handling multiple applications get access to the same hardware? Also, why are mmap and munmap operations required in ALSA? Right now, we do not have mmap and munmap operations exposed. Though the hardware constraints have "SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_MMAP_VALID" defined. Looks like, if we have to PulseAudio on top, mmap operations are required in ALSA. If there is a close enough ALSA implementation in the current Linux kernel that I can lookup, please point me to that. Any help/suggestions are welcome. Thanks, Srikanth

[alsa-devel] Query about code organization for kernel driver.
by Anksh Agarwal 25 May '10

25 May '10

Hi Everyone, I am currently working on a custom ARM based board and have succeeded in running alsa on my target. In this reference I have some basic queries and would be great if someone could give me pointers.This would help me in rorganizing the code as per acceptance from the group. since we planning to support a list of devices I wanted to keep the interface independent of playback/record session.this helps in switching to different devices in middle of playback. At any point a single device would be enabled. So i have another driver snd_device.c which uses sysfs interface to get device index or name to enable/disable device. The reason for this was that we could reuse a lot of code from the alsa-plugin(maemo). But then will it be right to put the device enable/disable code under sound/soc/xxxx/snd_device.c path, or can we split and place it seperately under sound/driver/xxxx/snd_device.c or any other suggested directory? i am not aware how to split the audio path enable/disable code from the soc driver and which would be ideal directory to place them, since there is hardly any interaction between playback and device enable/disable routines? I think the device enable/disable code outside sound/ directory wont be a good idea as its to be specifically used by alsa playback/record only. please suggest as this would help me a lot. Also let me know if any more info would help to get to a better conclusion. Really appreciate all the help. Thanks, Anksh

[alsa-devel] [PATCH] ASoC: Update Freescale i.MX SSI driver
by Stuart Longland 24 May '10

24 May '10

Hi all, Attached is a patch that corrects the i.MX SSI driver so that it compiles against the latest ASoC tree. I'm able to compile the driver with this patch, but haven't done any testing beyond this point... the update is quite naïve, based on changes I had seen to other drivers. I hope to give it a try on Monday, but in the meantime, here's the patch for others to try. -- Stuart Longland (aka Redhatter, VK4MSL) .'''.

[alsa-devel] [PATCH 0/2] Correct widget and PLL handling
by Jorge Eduardo Candelaria 21 May '10

21 May '10

Fix an issue when using 19.2 Mhz as clock input for TWL6040. Also, Drivers in TWL6040 can be modeled after PGA components of DAPM. This allows for better power management and also ensures that the DACs are enabled before the Drivers, reducing this way a pop-noise heard when powering up components.

[alsa-devel] [ice1712] Word Clock with Delta1010 E
by Bernhard Walle 21 May '10

21 May '10

Hi, we have a problem with the word clock input of the Delta 1010 E. At first: I modified the source code of envy24control to accept the Delta 1010 E as subdevice so that it allows to set the word clock. I'll post the patch after it works with the driver. However, the problem also exists when I use plain alsamixer or amixer. With the unmodified driver, I'm able to turn word clock on but whenever I record something, the arecord program (or Audacity) doesn't get any samples. With OSS (which we're using now but we're trying to switch to ALSA) my colleague Markus Prosch made a patch with lots of try & error that made the word clock working: http://opensound.hg.sourceforge.net/hgweb/opensound/opensound/rev/6a4bad6e7… When I try to "port" that patch to ALSA, the behaviour changes: The recording works, but the sample rate is too low so that it sounds quite strange. In any case: In the same hardware setup, it works flawlessly with OSS. Also, we had no problem with the older Delta 1010. It seems to be an incompatible change (or bug ;)) in revision E. Are there any devs here that know the hardware better and could help me in debugging that issue? Without any deeper sound driver knowledge and without any data sheet, that's quite hard for me. Thanks for your help! Regards, Bernhard PS: Please keep me in Cc since I'm not on the list.

[alsa-devel] [RFC] disabling ALSA period interrupts
by pl bossart 20 May '10

20 May '10

Howdy, When PulseAudio is used and all PCM is routed through PulseAudio (Fedora, Meego, etc), the notion of ALSA periods isn't very useful. PulseAudio uses a timer to refill buffers and the period interrupts are not used at all. So why not disable them entirely to reduce the number of wakeups? This is possible with a number of existing DMA controllers. The simple patch attached shows a proof-of-concept on HDAudio, it's been working for 5 hours on my Fedora12 laptop without any glitches and powertop does show _zero_ wakeups from the HDAudio controller (except on startup). I am told by my colleagues working in Windows environments that this is what's done on Vista/Windows7 btw. This isn't to say Windows is great but that artificial generation of not-needed interrupts is avoidable. There are probably some cases where you don't want this type of behavior (broken hardware, legacy code with multiple-buffering, disabled timer in PulseAudio), so I think it would make sense to request the disabling of interrupts when hw_params are set, since this is also the time when period sizes are set. I am aware that some changes would be needed in pcm_lib.c, where all the error checks are done. Takashi, Jaroslav, Lennart, what do you think? Feedback and suggestions welcome. Cheers - Pierre

[alsa-devel] First 50 milliseconds of audio clipping with dmix
by Tyler Conant 20 May '10

20 May '10

I'm trying to use dmix on an OMAP processor. I'm experiencing the first 50 ms of the sample getting clipped. When I aplay directly to the hw:0 I don't get the clipping. The difference I see between the alsa configuration between dmix and hw:0 is the start_threshold, stop_threshold and silence_size. When it's direct to hw:0 the start and stop threshold are equal to the buffer size. For dmix the start threshold is 1 and the stop threshold is 1445199872. Is this dmix which is setting the start and stop or is this aplay. I'm only guessing this is the reason why the first part is clipping. The only bug which seem similar is http://bugs.gentoo.org/show_bug.cgi?id=218641 and it's already been closed out.

[alsa-devel] [PATCH 1/1] ALSA: usb-audio: add support for Akai MPD16
by Krzysztof Foltman 19 May '10

19 May '10

The decoding routine is based on own reverse-engineering. It seems to recognize all the messages that MPD16 sends during normal operation (that is, via standard MIDI messages). Configuration (changing pad sensitivity, slider controller and MIDI notes) is not supported in this version.

[alsa-devel] [PATCH 0/4] McBSP smart idle and DMA op mode updates for ASoC
by Liam Girdwood 19 May '10

19 May '10

This series expands the OMAP mcbsp driver to support changing it's DMA operating mode and smart idle mode from client drivers. It's primarily aimed at lowering the power consumption for OMAP ASoC drivers by providing methods to gate clocks on the mcbsp interface at runtime. I've also added a patch to remove the mcbsp DMA op mode sysfs set functionality. I think DMA op mode is very specific to the mcbsp client driver _only_ and shouldn't really be changed by userspace. Please let me know if you use this feature and I'll drop this patch. Tony, can I get your ack to upstream via ALSA if it's ok Thanks Liam arch/arm/plat-omap/include/plat/mcbsp.h | 17 +++ arch/arm/plat-omap/mcbsp.c | 183 ++++++++++++++++++++++++++----- sound/soc/omap/omap-mcbsp.c | 22 ++++- sound/soc/omap/omap-mcbsp.h | 2 + 4 files changed, 194 insertions(+), 30 deletions(-)

[alsa-devel] ASoC: Dummy codec driver?
by Joonyoung Shim 19 May '10

19 May '10

Hi, I have a target(The cpu is S5PC110) which doesn't have audio codec, but it needs the audio device node to play audio at the TV via HDMI. The S5PC110 HDMI transmits itself to TV the audio data from I2S buffer, so i have made dummy codec driver to create audio device node and to transmit audio data to I2S buffer. How do you think about the dummy codec driver?

[alsa-devel] [PATCH - alsa-lib] tlv: Check dB range only within the control's volume range
by Peter Ujfalusi 19 May '10

19 May '10

The DB_RANGE need to be used on some HW, since the gain on volume control is not continuous, and has to be divided into several sub DB_SCALE ranges. ASoC has a feature to override the HW default volume range, and in this case when the volume range is less than the HW maximum we do not need to go through the whole DB_RANGE, but we need to stop where the kcontrol's maximum tell us. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- Hello, this patch fixes the ASoC related problem, when the volume is limited by the machine driver on a given control, which happen to have DB_RANGE gain mapping. The DB_RANGE has to have _only_ DB_SCALE type of mapping, since with LINEAR, MINMAX, MINMAX_MUTE it is not possible to accurately calculate the maximum dB limit on the control, when the volume is limited. Applications like PulseAudio need to know the actual dB range, and not only the theoretical maximum. src/control/tlv.c | 11 ++++++++--- 1 files changed, 8 insertions(+), 3 deletions(-) diff --git a/src/control/tlv.c b/src/control/tlv.c index cfd9b97..0ff052e 100644 --- a/src/control/tlv.c +++ b/src/control/tlv.c @@ -140,10 +140,13 @@ int snd_tlv_get_dB_range(unsigned int *tlv, long rangemin, long rangemax, pos = 2; while (pos + 4 <= len) { long rmin, rmax; - rangemin = (int)tlv[pos]; - rangemax = (int)tlv[pos + 1]; + long submin, submax; + submin = (int)tlv[pos]; + submax = (int)tlv[pos + 1]; + if (rangemax < submax) + submax = rangemax; err = snd_tlv_get_dB_range(tlv + pos + 2, - rangemin, rangemax, + submin, submax, &rmin, &rmax); if (err < 0) return err; @@ -156,6 +159,8 @@ int snd_tlv_get_dB_range(unsigned int *tlv, long rangemin, long rangemax, *min = rmin; *max = rmax; } + if (rangemax == submax) + return 0; pos += int_index(tlv[pos + 3]) + 4; } return 0; -- 1.7.1

[alsa-devel] [PATCH 1/1] ALSA: usb-audio: add support for Akai MPD16
by wdev＠foltman.com 18 May '10

18 May '10

From: Krzysztof Foltman <wdev(a)foltman.com> The decoding routine is based on own reverse-engineering.

[alsa-devel] Creating a /dev entry.
by Adish Kuvelker 18 May '10

18 May '10

Hello, I am writing a ALSA driver for the AtlasIII AC'97 Controller. The controller communicates with the AC'97 Codec and the necessary PCM, Sequencer, Control and Timer nodes are created in the /sys. Also I get the necessary information registered in the procfs under /proc/asound. However, I do not see any sound nodes created under /dev. Are these nodes created by the sound driver registration function which creates necessary files under /sys or will I have to use utilities like "snddevices" to create the "snd" node under /dev. I read that "snddevices" would create the necessary entries under /dev/snd, and I reckon that it does not create the entry "snd" under /dev. Although I am using kernel 2.6.19.2, it doesn't have the "udev" enabled. Will I need the "udev" to create these nodes under /dev? Regards; Aadish

[alsa-devel] RFC:
by Peter Ujfalusi 18 May '10

18 May '10

Hello, I apologize for the long mail, but I feel that I need to explain this in a bit longish way... ASoC core recently gained support for limiting the volume control's range (maximum), which is really useful in embedded systems. The implementation for this is really simple: The codec drivers are implementing the full range the HW can support. Machine drivers can than override the maximum volume on a given control if it is necessary. This works well with most of the controls: Volume controls without dB scale. Volume controls with DECLARE_TLV_DB_SCALE() Problems started to emerge, when the volume is limited on control, which has SNDRV_CTL_TLVT_DB_RANGE (from the sound/soc/codecs/tpa6130a2.c): static const unsigned int tpa6140_tlv[] = { TLV_DB_RANGE_HEAD(3), 0, 8, TLV_DB_SCALE_ITEM(-5900, 400, 0), 9, 16, TLV_DB_SCALE_ITEM(-2500, 200, 0), 17, 31, TLV_DB_SCALE_ITEM(-1000, 100, 0), }; static const struct snd_kcontrol_new tpa6140a2_controls[] = { SOC_SINGLE_EXT_TLV("TPA6140A2 Headphone Playback Volume", TPA6130A2_REG_VOL_MUTE, 1, 0x1f, 0, tpa6130a2_get_volsw, tpa6130a2_put_volsw, tpa6140_tlv), }; The original HW supported range is 0 .. 31 (-59 .. +4 dB). When the machine driver sets the limit to 21 (-6 dB), than the volume range is reported correctly as 0 .. 21, but snd_mixer_selem_get_playback_dB_range() reports range of -59 .. +4 dB. This is not correct, it should report: -59 .. -6 dB. If the control has single DECLARE_TLV_DB_SCALE() after the limiting both volume and dB range is reported correctly. The explanation for this is in the alsa-lib: src/control/tlv.c: /** * \brief Get the dB min/max values * \param tlv the TLV source returned by #snd_tlv_parse_dB_info() * \param rangemin the minimum value of the raw volume * \param rangemax the maximum value of the raw volume * \param min the pointer to store the minimum dB value (in 0.01dB unit) * \param max the pointer to store the maximum dB value (in 0.01dB unit) * \return 0 if successful, or a negative error code */ int snd_tlv_get_dB_range(unsigned int *tlv, long rangemin, long rangemax, long *min, long *max) { int err; switch (tlv[0]) { case SND_CTL_TLVT_DB_RANGE: { unsigned int pos, len; len = int_index(tlv[1]); if (len > MAX_TLV_RANGE_SIZE) return -EINVAL; pos = 2; while (pos + 4 <= len) { long rmin, rmax; rangemin = (int)tlv[pos]; rangemax = (int)tlv[pos + 1]; err = snd_tlv_get_dB_range(tlv + pos + 2, rangemin, rangemax, &rmin, &rmax); if (err < 0) return err; if (pos > 2) { if (rmin < *min) *min = rmin; if (rmax > *max) *max = rmax; } else { *min = rmin; *max = rmax; } pos += int_index(tlv[pos + 3]) + 4; } return 0; } case SND_CTL_TLVT_DB_SCALE: { int step; *min = (int)tlv[2]; step = (tlv[3] & 0xffff); *max = *min + (long)(step * (rangemax - rangemin)); return 0; } case SND_CTL_TLVT_DB_MINMAX: case SND_CTL_TLVT_DB_MINMAX_MUTE: case SND_CTL_TLVT_DB_LINEAR: *min = (int)tlv[2]; *max = (int)tlv[3]; return 0; } return -EINVAL; } In case of DECLARE_TLV_DB_SCALE(), the SND_CTL_TLVT_DB_SCALE case is taken, and the control's maximum, and minimum range are used for the dB scale limit calculation. But, when SNDRV_CTL_TLVT_DB_RANGE is used (tpa6130a2 driver), than that case will dismisses the control's maximum and minimum range, and goes through the whole TLV struct, and reports the HW supported range. If it would stop at the driver reported maximum, than the dB range reported would be correct. So a 'simple' patch to alsa-lib would solve this. But what happens, if we want to limit control, which has DB_MINMAX, DB_MINMAX_MUTE, or DB_LINEAR? There is no way to actually limit those in a way, that the dB scale reported would be correct. We just stretch the steps bigger, like what happens with the SNDRV_CTL_TLVT_DB_RANGE in the tpa6130a2 driver. When looking for users of DB_LINEAR I have found 8 drivers, DB_MINMAX is used by usbmixer only, the DB_MINMAX_MUTE has no users at all. Since both DB_LINEAR and DB_MINMAX can be presented as DB_SCALE, and the effort to convert the drivers should not be that big. In this way, we will only have drivers using DB_SCALE in kernel, we can mark the other DB_ types as deprecated (but keeping the support for out of tree drivers), and the alsa-lib's tlv code can be adjusted to support properly the volume limiting. If there is interest, than the ALSA core could also gain support for platform/configuration dependent volume limiting. If this is too big change to ALSA (which I think it is not, since for the user it makes no difference, and the volume range, dB scale not going to be changed), than probably cleaning up the sound/soc/ to use _only_ DB_SCALE type for volume controls might be the solution, since the volume limiting feature is only in ASoC AFAIK. Either way, the alsa-lib's src/control/tlv.c:snd_tlv_get_dB_range function in case of SND_CTL_TLVT_DB_RANGE needs some fix to handle the situation, when the volume range is _not_ at the HW supported range. To summarize, I'd like to do (or ask help to do) one of the following [1] Replace the use of DB_LINEAR, DB_MINMAX with DB_SCALE in all drivers under sound/ Document, that the now unused DB_ types are deprecated Fix alsa-lib to support the volume limiting in regards of dB scale [2] Replace the use of DB_LINEAR with DB_SCALE in all drivers under sound/soc/ Fix alsa-lib to support the volume limiting in regards of dB scale What do you think? -- Péter

[alsa-devel] soc multi chip support
by Attila RS 17 May '10

17 May '10

Hi, I have 2 of the same audio codecs connected to an omap (each codec has it's own i2c address and each has its own mcbsp channel). I can configure and use each one individually, but have not found a way to configure both at the same time so that each codec shows up as an alsa device. I did some searching and found that this may not be supported yet. Is that the case or has anyone done this yet or is working on it? Attila

Hello, While testing suspend, it has been noticed, that the driver would try to power off the codec more than once. Since this case handled in the driver, and results no functional defect we can lower the noise in the kernel log. Also avoid the root cause of the multiple off calls by filtering BIAS_OFF request when the codec was already OFF. --- Felipe Balbi (1): ASoC: tlv320dac33: Use dev_dbg in dac33_hard_power function Peter Ujfalusi (1): ASoC: tlv320dac33: Avoid powering off while in BIAS_OFF sound/soc/codecs/tlv320dac33.c | 5 ++++- 1 files changed, 4 insertions(+), 1 deletions(-)

But I like to use also the external I/O- terminal, delivered with ElitePro- cards. Is there any chance to get this working. I'm no real linux kernel hacker, but I can give You every infomation about the terminal, if You need (I had already disassembled the I/O- box). I do not need the effects, but In like to use the additional in-/outputs and volume knob. To use the ir- control, would be great, too. -- Kind Regaards Sebastian Reinhardt

Smatch complains that if (dev == SNDRV_CARDS) we're one past the end of the array. That's unlikely to happen in real life, I suppose. Also smatch complains about "strcpy(card->shortname, pcm->name);" The "pcm->name" buffer is 80 characters and "card->shortname" is 32 characters. If you follow the call paths it turns out we never actually use more than 16 characters so it's not a problem. But anyway, let's make it easy for people auditing this in the future.

[alsa-devel] [PATCH 0/4] updates for Intel SandyBridge/CougarPoint HDMI codec V2
by Wu Fengguang 17 May '10

17 May '10

Hi Takashi, The Intel SandyBridge/CougarPoint HDMI codec is very similar to the IbexPeak HDMI codec, except that it exports one more Audio Converter. Now we have 3 Audio Converters, each of them present one HDMI PCM device: (and expect a 4th HDMI PCM device in future) $ aplay -l | grep HDMI card 0: PCH [HDA Intel PCH], device 3: INTEL HDMI 0 [INTEL HDMI 0] card 0: PCH [HDA Intel PCH], device 7: INTEL HDMI 1 [INTEL HDMI 1] card 0: PCH [HDA Intel PCH], device 8: INTEL HDMI 2 [INTEL HDMI 2] So enable devices minors to support more than 8 PCM playback devices. Thanks, Fengguang

[alsa-devel] HDA Intel - Activating S/PDIF output on an HP laptop (8510W).
by Huw Hawkins 15 May '10

15 May '10

Hi all, I have been quite happily using the intel HDA drivers to get audio on my Compaq 8510W, everything works fine out of the box with the exception of the HDMI output. After some poking around I see that this is because the digital output is disabled by the HP model specific code. Setting the model as "basic" gives me perfect audio on the HDMI output, but jack sensing is completely messed up, the mute button status is inverted and it is not possible to get sound from the internal speakers. Setting the model as "HP" diables the digital audio on the HDMI port. It seems from a google search that there are a few people around with the same issue on HP laptops with HDMI output. I don't really have the time to dig through and understand the spec/code for the driver to try to fix the problem myself. On the other hand I probably could spend an hour or two over the next couple of weeks testing or investigating the hardware if someone else wants to have a go. Any takers? Huw

[alsa-devel] [RFC][PATCH] fall back to reserved minor numbers
by Wu Fengguang 14 May '10

14 May '10

When the static minor numbers collide because of too many devices, fall back to the reserved minor numbers 2 and 3. This for example will allow Intel HDMI audio driver to create three PCM devices (index 3, 7, 8; the minor number of the last index will otherwise collide with the first record device). The other option is to force enable CONFIG_SND_DYNAMIC_MINORS.

The first two patches do this dirty work, however I'm not sure if they will introduce some side effects. The last three patches are more straightforward and safe. Thanks, Fengguang

[alsa-devel] underruns over network
by Preston Kulaga 14 May '10

14 May '10

Hello, I am quite new to ALSA and am having a bit of trouble with underruns. I am working on a voice communication system via udp sockets and am getting underruns on receiving end very sporadically (capture end is fine). Have done a great deal of reading and searching on reasons for this but am not sure what approach is best to limit the underruns. I must not be transferring the data quickly enough over the network before the ring buffer runs out of data, which makes sense, but how would you accommodate for this? I am able to buffer a large amount of network data and then playback successfully, but obviously the delay induced is so significant that it makes real-time communication impossible. If I just recover/prepare the stream after an underrun the audio is horribly distorted. Is there a normal way of dealing with this issue that I am unable to find? I would appreciate any insight, guidance, references for any help you can give me. Thank You.

[alsa-devel] ALSA and Ubuntu addendum

Addendum: I forgot one thing that doesn't work on Ubuntu either (but works on openSUSE): PCM streams in signed 8 bit format have terrible sound artefacts on Ubuntu. If I convert them to unsigned 8 bit format, they are played correctly. But in signed format, it sounds totally broken.

[alsa-devel] ALSA and Ubuntu
by Andreas Falkenhahn 13 May '10

13 May '10

Hi, I just downloaded the latest Ubuntu Live CD (10.04) to try my app on it. It is a plain X11 app using ALSA for sound output. I developed it on openSUSE 11.2 and thought to give it a try on Ubuntu... that was a mistake, because on Ubuntu, there seem to be lots of errors with ALSA. Here are some observations: 1) snd_pcm_status_get_tstamp() always returns 0 for sec/usec. 2) snd_pcm_status_get_state() always returns SND_PCM_STATE_RUNNING, even when the PCM stream has long reached a buffer underrun. 3) snd_pcm_delay()'s return value doesn't fall below ~7000 samples or so. Even when the buffer has underrun, the return value is not 0 but about ~7000 samples. This makes it nearly impossible to detect when I should start writing new samples to the buffer... Could someone enlighten me what's going on there? Is this a known issue with Ubuntu? I'm not using any weird addons or stuff. It's really just the latest Ubuntu live CD. As I said, on openSUSE everything is working just fine. But on Ubuntu, hell is really breaking loose here... Thanks for help, Andreas

[alsa-devel] HP dv series mute LED problems?
by Kunal Gangakhedkar 13 May '10

13 May '10

Hi Takashi, The commit 26ebe0a28986f4845b2c5bea43ac5cc0b9f27f0a seems to undo the mute LED gpio fixes - at least on my dv6 series laptop. Maybe, we need to come up with a better solution to accommodate the problem reported in this thread: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-May/027352.html I believe, that's the reason for the commit, right? Let me do a bit more digging. Thanks, Kunal

[alsa-devel] Use of start_frame in usbusx2yaudio.c
by Sarah Sharp 12 May '10

12 May '10

Are there any drivers in the kernel that set urb->start_frame on every URB? Could those drivers handle it if only the first URB they submitted to the host controller was scheduled for that frame ID, and all the rest of the URBs were scheduled ASAP? I see there are three drivers that set start_frame (while not setting URB_ISO_ASAP): - drivers/isdn/hisax/st5481_d.c - drivers/usb/core/devio.c - sound/usb/usx2y/usbusx2yaudio.c I'm not really sure what usbusx2yaudio.c is doing. I think when one URB completes, it sets the next URB's start_frame to the previous URB's start_frame plus the number of URBs (2 by default) times the number of packets (4 by default). Isn't this basically like setting URB_ISO_ASAP? I really can't tell what fall back method is if this submission fails. What is usbusx2yaudio.c attempting to do? I've tried to get an overall picture of what it expects the isochronous scheduling to look like, but I'm finding the driver a bit hard to read. I'm not too worried about the other two drivers. The code in st5481_d.c seems to fall back fine to URB_ISO_ASAP if the submission with the start_frame set failed. devio.c is usbfs, and I can't tell what userspace drivers do. (It could be argued that if they needed such tight control over isoc, they should have written a kernel driver.) Sarah Sharp

[alsa-devel] ESI Maya44 PCI – mixer code errors
by Alex Chernyshoff 12 May '10

12 May '10

Hello! In the current release of ESI Maya44 PCI ALSA driver (1.0.23) selection of “Mic In” capture source is impossible. “Microphone” check in the “Switches “ mixer tab actually does not select anything – no recording audio at all, and the Phantom power switch does not perform correctly too. Original, Rainer Zimmermann patch (for ALSA 1.0.19) performs well, but can`t be compiled with the current ALSA and kernel26. Sadly... I've look into current, rewritten, code in the file ./alsa-driver-1.0.23/alsa-kernel/pci/ice1712/maya44.c and found some interesting details. Further, I've add some changes, and “Mic In” selection now works, but only partially. (Below) In the original maya44.c file, from Rainer Zimmermann patch, some definitions of I/O flags seems as a simple mask: #define GPIO_PHANTOM_OFF (1<<2) #define GPIO_MIC_RELAY (1<<4) #define GPIO_SPDIF_IN_INV (1<<5) /* CHECK! */ #define GPIO_MUST_BE_0 (1<<7) Current branch of Maya44 code is rewritten, and these definitions look like the indexes #define GPIO_PHANTOM_OFF 2 #define GPIO_MIC_RELAY 4 #define GPIO_SPDIF_IN_INV 5 #define GPIO_MUST_BE_0 7 So, at the row 396 of the current branch - maya44.c changed = maya_set_gpio_bits(chip->ice, GPIO_MIC_RELAY, sel ? GPIO_MIC_RELAY : 0); I change this code to: changed = maya_set_gpio_bits(chip->ice, (1 << GPIO_MIC_RELAY), sel ? (1 << GPIO_MIC_RELAY) : 0); And finally, at the row 348 of the current maya44.c /* known working input slots (0-4) */ #define MAYA_LINE_IN 1 /* in-2 */ #define MAYA_MIC_IN 4 /* in-5 */ but usable channels are 2 and 4 (from datasheet), therefore I change defines to #define MAYA_LINE_IN 1 /* in-2 */ #define MAYA_MIC_IN 3 /* in-4 */ After that, we can get some usability from mixer. Now, the “Microphone” check can select “Mic In”, and real audio path from microphone to ADC works! But only once. After that, in the “Capture” tab of mixer, “Mute” knob visually change state to muted. Some kind of strange cross influence between mixer tabs :-) Pressing to this “Mute” knob switches back “Mic In” capture source to “Line”, and clear Phantom Power check. (Very strange) And finally, if we check “Microphone” again - “Mic In” became selected again, and “Mute” enter in “unpressed” state again too. But microphone capture became again operable. Circle is closed. Excuse me for some kind of messed story and poor English (my native is Russian), but such description of mixer behavior maybe useful for understanding... I can't resolve more mistakes in the code. Perhaps, author can do it more better than me. I have a hardware – ESI Maya44 PCI audio board installed to working and usable Arch Linux i686 system. I'm ready for testing, and glad to do it! Sincerely Alex Chernyshoff

[alsa-devel] alsa-driver patches
by Eliot Blennerhassett 12 May '10

12 May '10

Hi Takashi, since the acceptance of asihpi driver, and move to alsa-kernel, you created a couple of patch files in alsa-driver/pci/asihpi (that add conditional compilation for older kernels) Can you tell me how these patches are generated and maintained? (I guess this applies to any driver with this kind of patch). I think that this arrangement means that my one upstream file needs to be converted to two files (kernel .c + patch) when I submit updates? thanks -- Eliot Blennerhassett AudioScience Inc.

When exactly do you hear this noise? The WM8993 driver will not power up the speaker outputs unless they are in use and there are no audio paths configured to the speakers by default. Are you configuring an audio path in the CODEC at system startup? Which mode do you have the WM8993 speaker drivers in - class D or class A/B? It might be helpful to capture all the register writes done when bringing up the WM8993. Also, if you are configuring an audio path from an analogue input you should check that there is no DC offset present in the input signal - if there is one then the WM8993 will reproduce it into the output path, which would result in an audible noise. > In 53242c68333570631a15a69842851b458eca3d99, > there was a line: > > + ret = wm8993_set_fll(codec->dai, 0, wm8993->fll_src, > + fll_fref, fll_fout); > + > but in lastest version of wm8993 driver, wm8993_set_fll will do > nothing we the second parameter(fll_id) is 0, so, I don't know what > this function want to do, > Cound you give me some idea ? This parameter specifies which of the FLLs/PLLs in the device to configure. Since the WM8993 has only one FLL it just ignores this parameter, other devices with multiple FLLs such as the WM8994 need this to select between the FLLs.

[alsa-devel] snd-hda-intel - wallclk patch

[alsa-devel] [PATCH] ASoC: core: Fix for the volume limiting when invert is in use
by Peter Ujfalusi 11 May '10

11 May '10

If the register for the volume needs invert, than the inversion need to be done from the chip maximum, and not from the platform dependent limit. Introduce soc_mixer_control.platform_max value, which initially equals to chip maximum. The snd_soc_limit_volume function only modify the platform_max, all volsw_info call returns this as well. The .max value holds the chip default (maximum), and it is used for the inversion, if it is needed. Additional check in the volsw_info call has been added to check the validity of the platform_max in case, when custom macros used by codec drivers are not initializing it correctly. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- Hello, Normal, and inverted volume controls now can be limited, and both behave correctly. Has been tested on twl4030, tpa6130a2, and tlv320dac33 codec drivers. The patch is generated against Takashi's topic/asoc branch, but I think it should be fine with Mark's tree as well.

[alsa-devel] [PATCH] hda_intel: Fixes distorted recording on US15W chipset
by Shahin Ghazinouri 11 May '10

11 May '10

The HDA controller in US15W (Poulsbo) reports inaccurate position values for capture streams when using the LPIB read method, resulting in distorted recordings. However, using the position buffer is broken for playback streams, resulting in a fallback to the LPIB method with the current driver. This patch works around the issue by independently detecting the read position method for capture and playback streams. The patch will not have any effect if the position fix method is explicitly set.

[alsa-devel] [RFC] G.723-24 format patch
by Ben Collins 10 May '10

10 May '10

I'm writing a driver for a card that only has hardware support for G.723-24 ADPCM format. I am working around the lack of support in alsa at the moment for this format, but wanted to take a crack at implementing it properly. G.723-24 is a 3-bit signed sample at a fixed 8khz mono sample rate (24000 bit rate). Basically means you need to take in at least 3 bytes (8 samples) minimum for processing the standard packed version. I don't have hardware that supports it, but since I was in the code, I added a G723_24_1B format for producing 1 sample per byte (3 lower bits are actual sample), but for my use I am producing the standard packed stream. Only question I had is that since this is signed, should I expect or want the _1B version to be a 1 byte sign extended version of the 3-bit sample, or just expect the lower 3 bits of the byte to be the g723-24 sample? Looking at other unpacked examples, I assume the latter rather than the former. diff --git a/include/sound/asound.h b/include/sound/asound.h index 1f57bb9..16fc633 100644 --- a/include/sound/asound.h +++ b/include/sound/asound.h @@ -212,7 +212,9 @@ typedef int __bitwise snd_pcm_format_t; #define SNDRV_PCM_FORMAT_S18_3BE ((__force snd_pcm_format_t) 41) /* in three bytes */ #define SNDRV_PCM_FORMAT_U18_3LE ((__force snd_pcm_format_t) 42) /* in three bytes */ #define SNDRV_PCM_FORMAT_U18_3BE ((__force snd_pcm_format_t) 43) /* in three bytes */ -#define SNDRV_PCM_FORMAT_LAST SNDRV_PCM_FORMAT_U18_3BE +#define SNDRV_PCM_FORMAT_G723_24 ((__force snd_pcm_format_t) 44) /* 8 samples in 3 bytes */ +#define SNDRV_PCM_FORMAT_G723_24_1B ((__force snd_pcm_format_t) 45) /* 1 sample in 1 byte */ +#define SNDRV_PCM_FORMAT_LAST SNDRV_PCM_FORMAT_G723_24_1B #ifdef SNDRV_LITTLE_ENDIAN #define SNDRV_PCM_FORMAT_S16 SNDRV_PCM_FORMAT_S16_LE diff --git a/include/sound/pcm.h b/include/sound/pcm.h index de6d981..031e2cd 100644 --- a/include/sound/pcm.h +++ b/include/sound/pcm.h @@ -173,6 +173,8 @@ struct snd_pcm_ops { #define SNDRV_PCM_FMTBIT_U18_3LE (1ULL << SNDRV_PCM_FORMAT_U18_3LE) #define SNDRV_PCM_FMTBIT_S18_3BE (1ULL << SNDRV_PCM_FORMAT_S18_3BE) #define SNDRV_PCM_FMTBIT_U18_3BE (1ULL << SNDRV_PCM_FORMAT_U18_3BE) +#define SNDRV_PCM_FMTBIT_G723_24 (1ULL << SNDRV_PCM_FORMAT_G723_24) +#define SNDRV_PCM_FMTBIT_G723_24_1B (1ULL << SNDRV_PCM_FORMAT_G723_24_1B) #ifdef SNDRV_LITTLE_ENDIAN #define SNDRV_PCM_FMTBIT_S16 SNDRV_PCM_FMTBIT_S16_LE diff --git a/sound/core/pcm_misc.c b/sound/core/pcm_misc.c index ea2bf82..c7f8da4 100644 --- a/sound/core/pcm_misc.c +++ b/sound/core/pcm_misc.c @@ -128,6 +128,10 @@ static struct pcm_format_data pcm_formats[SNDRV_PCM_FORMAT_LAST+1] = { .width = 4, .phys = 4, .le = -1, .signd = -1, .silence = {}, }, + [SNDRV_PCM_FORMAT_G723_24] = { + .width = 3, .phys = 3, .le = -1, .signd = 1, + .silence = {}, + }, /* FIXME: the following three formats are not defined properly yet */ [SNDRV_PCM_FORMAT_MPEG] = { .le = -1, .signd = -1, @@ -186,6 +190,10 @@ static struct pcm_format_data pcm_formats[SNDRV_PCM_FORMAT_LAST+1] = { .width = 18, .phys = 24, .le = 0, .signd = 0, .silence = { 0x02, 0x00, 0x00 }, }, + [SNDRV_PCM_FORMAT_G723_24_1B] = { + .width = 3, .phys = 8, .le = -1, .signd = 1, + .silence = {}, + }, };

Yes, the driver just needs to make sure that whatever it uses to return the current setting when queried is going to give the right answer from the time the control is set up, normally by initialising variables though if you're doing things like read data back from hardware then you may be able to rely on the hardware defaults.

[alsa-devel] ALSA Control Interface - default values?
by Max Klein 10 May '10

10 May '10

Hello, when writing an alsa driver, in the info callback of the control I can specify which range of values this control does accept (uinfo->value.integer.min and .max). If I put 1 as minimum and 10 as maximum for example, I would expect that the default value of this control is something in between the range, e.g. 1, after the driver is loaded. But I figured out, that ALSA initializes the control with a value of 0, which is not in between the range. Can someone please tell me why ALSA initializes the Control with a value of zero, even if the minimum in the info callback is 1 ? Is there any way to initialize the control with some "default" values, aside of snd_ctl_add()? Best regards and thanks for your help! Max -- "Feel free" - 10 GB Mailbox, 100 FreeSMS/Monat ...

What exactly is an "amplifying pop" (do you mean that you hear an unwanted noise, or is there something else)? Please ensure that you are using the latest version of the WM8993 driver (including wm_hubs.c) to make sure that you have all the latest bug fixes and enhancements. If you are not using single ended line outputs from the device you should also mark the line outputs as being in differential mode for maximum power savings. > Our board using a WM8993 codec, and I We have problem about ampifying pops, > when the system resume, We will heard a ampifying pop, (but it's silence on > the suspend processing), We also noticed that when system boot, also can > hear one ampifying pop. System resume and power up are identical from the point of view of the CODEC driver. > From I know, the WM8993's codec have a internal amplifier, I don't know how > to control this amplifier. The WM8993 has a large number of amplifiers, there are many audio paths in the device and most of them have some amplification control. Which outputs are you concerned about?

[alsa-devel] [PATCH] ASoC: core: Support for limiting the volume
by Peter Ujfalusi 10 May '10

10 May '10

Add support for the core to limit the maximum volume on an existing control. The function will modify the soc_mixer_control.max value of the given control. The new value must be lower than the original one (chip maximum) If there is a need for limiting a gain on a given control, than machine drivers can do the following in their snd_soc_dai_link.init function: snd_soc_limit_volume(codec, "TPA6140A2 Headphone Playback Volume", 21); This will modify the original 31 (chip maximum) to 21, so user space will not be able to set the gain higher than this.

The Intel IOMMU code will use dev->dma_mask and dev->coherent_dma_mask properly. It is not limited to 4GiB, but it will tend to give virtual DMA addresses below 4GiB even when a device is capable of more; it'll only give out higher addresses when the address space below 4GiB is exhausted. -- dwmw2

[alsa-devel] [PATCH 2.6.34-rc5 v2] HID: Prodikeys PC-MIDI HID Driver
by Don Prince 10 May '10

10 May '10

A specialised HID driver for the Creative Prodikeys PC-MIDI USB Keyboard. The Prodikeys PC-MIDI is a multifunction keyboard comprising a qwerty keyboard, multimedia keys and a touch sensitive musical keyboard. The specialised HID driver adds full support for the musical keyboard and extra multimedia keys which are not currently handled by the default HID driver. The specialised HID driver interfaces with Alsa, and presents the midi keyboard as a Rawmidi device. Sustain duration, octave shifting and the midi output channel can be read/written form userspace via sysfs.

[alsa-devel] [PATCH 0/5] Enabling ASoC paths over suspend
by Mark Brown 10 May '10

10 May '10

The following patch series implements support for keeping some paths in the audio codec enabled while the system is suspended. This is primarily intended for mobile phones, where the GSM modem is normally capable of supporting a voice call with no intervention from the CPU so power can be saved by suspending the Linux system. This is done by allowing DAPM nodes to be marked as ignoring suspend. Any audio paths between two widgets set up like this at suspend time will be kept active and the CODEC device will not be suspended. The existing testing is very light (especially for digital paths), the intention is to do more of that get this merged into Takashi's tree early next week. git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git suspend-enable Mark Brown (5): ASoC: Remove unneeded suspend bias managment from CODEC drivers ASoC: Remove unused DAPM suspend flag ASoC: Refactor DAPM suspend handling ASoC: Support leaving paths enabled over system suspend ASoC: Allow active paths from the GSM modem while the GTA02 is suspended include/sound/soc-dapm.h | 3 +- sound/soc/codecs/ak4535.c | 1 - sound/soc/codecs/cq93vc.c | 2 +- sound/soc/codecs/ssm2602.c | 1 - sound/soc/codecs/stac9766.c | 3 - sound/soc/codecs/tlv320aic23.c | 1 - sound/soc/codecs/tlv320aic3x.c | 2 +- sound/soc/codecs/tlv320dac33.c | 3 - sound/soc/codecs/twl4030.c | 1 - sound/soc/codecs/twl6040.c | 1 - sound/soc/codecs/uda1380.c | 1 - sound/soc/codecs/wm8350.c | 3 - sound/soc/codecs/wm8510.c | 2 +- sound/soc/codecs/wm8711.c | 2 +- sound/soc/codecs/wm8728.c | 2 +- sound/soc/codecs/wm8731.c | 1 - sound/soc/codecs/wm8903.c | 1 - sound/soc/codecs/wm8940.c | 1 - sound/soc/codecs/wm8960.c | 2 +- sound/soc/codecs/wm8974.c | 2 +- sound/soc/codecs/wm9712.c | 3 - sound/soc/codecs/wm9713.c | 3 - sound/soc/s3c24xx/neo1973_gta02_wm8753.c | 8 +++ sound/soc/soc-core.c | 35 ++++++++++- sound/soc/soc-dapm.c | 92 +++++++++++++++++++----------- 25 files changed, 107 insertions(+), 69 deletions(-)

[alsa-devel] Not all channels working with IDT 92HD83C1X5
by Thierry Reding 10 May '10

10 May '10

Hi, I have a board with an IDT 92HD83C1X5 codec connected to an Intel HDA controller. When running a older "reference" Ubuntu 9.04 (provided by the vendor) the codec works fine. I've been diffing the sources provided of the 2.6.28 kernel against vanilla 2.6.28 and couldn't find any significant changes regarding HDA or the patch_sigmatel.c that has the support for this codec. However, when I use kernel 2.6.34-rc6 on the same hardware, only one channel is working properly, all others remain muted. After some investigation I came up with the attached patch that makes all channels work again. I am aware that this is far from being acceptable code and that this is only a workaround. Still, I am interested in fixing this properly, but I don't really know where to start. Also attached is an extract of dmesg with the actual output of the debugging messages added by the attached patch. Cheers, Thierry

[alsa-devel] [PATCH 10/11] ASoC: S3C64XX: IISv4: Add CPU driver
by Jassi Brar 10 May '10

10 May '10

Add the CPU driver for the IISv4 block found on S3C6410. For now, the driver is almost a copy of s3c64xx-i2s.c but it should diverge as more IISv4 specific stuff is added.

[alsa-devel] Xonar D1 front panel microphone not working in kernel 2.6.33
by Peter Hercek 08 May '10

08 May '10

It is not possible to record anything from my front panel microphone jack after I updated kernel to 2.6.33. It still works OK with kernel 2.6.32.10, but does not work with 2.6.33.3, and it did not work with 2.6.33.rc8 too. The front panel switch in alsamixer switches only output but not input (mic) now. Before, the switch had impact on both output and input. When I activate the back panel on the card everything is working well (back panel connectors are active, front panel connectors are inactive). When I activate the front panel then the front panel microphone is not working (back panel microphone works). The alsamixer front panel switch does not have impact on the microphone any more and no switch was added to control the microphone separately from the output. The alsa version is 1.0.23. I use 32 bit kernels. My brother uses 64 bit kernels and the problem is the same for him too. Although he uses Xonar DX. Any idea how to get this fixed? I attached output of alsa-info.sh for both cases. Maybe it is only some new configuration thing which needs to be done but if not then I should be able to test a patch to vanilla kernel 2.6.33.3 if needed. Peter.

Hi all, I'm developing a driver for wm8974 codec with Freescale mx27ipcam board with linux kernel 2.6.19.2. Our work is based on the mx27vis-wm8974 driver available in alsa-driver-1.0.22. After installing all necessary driver modules, when I trying to playback some wav file using "cat xx.wav > /dev/dsp" command, I got the following error message: "ALSA pcm_lib.c:1709: playback write error (DMA or IRQ trouble?)". This seems to be caused by the full of the transmitting buffer since I can check that "hw_ptr=0x800/buffer_size=0x4000/appl_ptr=0x4800". The hw_ptw doesn't update anymore. It seems that there is something wrong with the DMA operation. Actually, the DMA dest. address is the SSI1's TX0 FIFO. On the other hand, SSI1's SFCSR=0x440844, which indicates that there are 8 bytes data in the TX0 FIFO, which will not generate DMA request as the FIFO empty watermark is 4. It is very possible that the SSI1 does not shift data from the FIFO, which causes no DMA request generated and thus DMA freezes. Our board connects wm8974 codec to mx27 gpio PC20~23 pins (signal name are SSI1_XXX). On these io pins, we can check the FS and bit clock have been generated. The PC20~PC23 gpio pins have been configure as SSI function. My driver also configures AUDMUX host port1(HP1,wired to SSI1 internally) to peripheral port 1(PP1). But I'm not sure whether PP1 is mapped to PC20~23. Is this configuration right? If this map is wrong, the FS and Bit Clock generated by wm8974 can not be routed to SSI1 module, which is the potential reason for no data are shifted. Who can shed some light on the map between mx27 AUDMUX port and GPIO pins? Any more possible reasons which will freeze DMA transfer? Regards, Jie

[alsa-devel] [PATCH 0/2] ASoC: tpa6130a2: Use the core to set the gain limit
by Peter Ujfalusi 07 May '10

07 May '10

Hello, Core will receive support for limiting the volume on controls, so the custom way of doing it in the tpa driver is no longer needed. There was also a problem within the tpa driver when custom limit has been configured. The second patch fixes that. The combination of the snd_soc_limit_volume, and this series works really nicely together. --- Peter Ujfalusi (2): Revert "ASoC: tpa6130a2: Support for limiting gain" ASoC: tpa6130a2: Fix for the custom kcontrol functions include/sound/tpa6130a2-plat.h | 1 - sound/soc/codecs/tpa6130a2.c | 90 +++++++-------------------------------- 2 files changed, 16 insertions(+), 75 deletions(-)

We do such tricks on other OS where IRQ latency as high as some tens of milliseconds. So we queue EHCI transfers well in advance and update access their contents (for both input and output) from audio context. I considered implementing this idea to the Linux USB audio driver as well. > Or to be precise it could be done with coherent memory, but you'd risk > transfering partially updated buffers, as you cannot know when DMA will > be done and we don't guarantee that DMA will be done right as we transfer. If the memory is coherent, it should be possible. And if buffers are only partially updated, the audio buffer scheduling is too tight. IOW, the configured buffer size of audio clients in userspace is too small. This is OT now I believe, I will start another thread for this topic once I have something to show. Thanks, Daniel

Hmm, I think I finally found the reason for all this confusion. No idea why I didn't come up with the following explanation any earlier. The problem is again (summarized): On 64bit machines, with 4GB or more, the allocated buffers for USB transfers might be beyond the 32bit boundary. In this case, the IOMMU should take care and install DMA bounce buffer to copy over the buffer before the transfer actually happens. The problem is, however, that this copy mechanism takes place when the URB with its associated buffer is submitted, not when the EHCI will actually do the transfer. In the particular case of audio drivers, though, the contents of the buffers are likely to change after the submission. What we do here is that we map the audio stream buffers which are used by ALSA to the output URBs, so they're filled asychronously. Once the buffer is actually sent out on the bus, it is believed to contain proper audio date. If it doesn't, that's due to too tight audio timing or other problems. This breaks once buffers are magically bounced in the background. So - long story short: these audio buffers need to be DMA coherent. The patch below does that, and Pedro excessively tested this patch for weeks now :) It was just the final explanation _why_ it does the right thing that was yet missing. If nobody has objections, can we still squeeze it into .34? Thanks, Daniel

[alsa-devel] [PATCH RFC v1] ASoC: core: Support for limiting the volume
by Peter Ujfalusi 07 May '10

07 May '10

Add support for the core to limit the maximum volume on an existing control. The function will modify the soc_mixer_control.max value of the given control. The new value must be lower than the original one (chip maximum) If there is a need for limiting a gain on a given control, than machine drivers can do the following in their snd_soc_dai_link.init function: snd_soc_limit_volume(codec, "TPA6140A2 Headphone Playback Volume", 21); This will modify the original 31 (chip maximum) to 21, so user space will not be able to set the gain higher than this. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- Hello Mark, Liam, So this is my proposed way of doing the volume limiting within the core. By looking around the code, this should be safe. With this simple function all machine driver can limit gains on a given control in a way, that the codec/amp driver does not need to be involved.

[alsa-devel] [PATCH 2.6.34-rc5] HID: Prodikeys PC-MIDI HID Driver
by dhprince.devel＠yahoo 07 May '10

07 May '10

A specialised HID driver for the CreativeLabs Prodikeys PC-MIDI USB Keyboard. The Prodikeys PC-MIDI is a multifunction keyboard comprising a qwerty keyboard, multimedia keys and a touch sensitive musical keyboard. The specialised HID driver adds full support for the musical keyboard and extra multimedia keys which are not currently handled by the default HID driver. The specialised HID driver interfaces with Alsa, and presents the midi keyboard as a Rawmidi device. Sustain duration, octave shifting and the midi output channel can be read/written form userspace via sysfs. Signed-off-by: Don Prince <dhprince-devel(a)yahoo.co.uk> --- The keyboard can be viewed here http://www.prodikeys.com/products/Prodikeys_PC-MIDI/ The driver and a simple wxWidgets based UI application is available (in tar.gz format) at the Sourceforge project page http://sourceforge.net/projects/pc-midi-linux/ Apply patch with patch -p1 < <path to the driver patch> --- diff -X /opt/scripts/diff-exclude.txt -Npaur a/Documentation/ABI/testing/sysfs-driver-hid-prodikeys b/Documentation/ABI/testing/sysfs-driver-hid-prodikeys --- a/Documentation/ABI/testing/sysfs-driver-hid-prodikeys 1970-01-01 01:00:00.000000000 +0100 +++ b/Documentation/ABI/testing/sysfs-driver-hid-prodikeys 2010-05-05 12:54:37.224487960 +0100 @@ -0,0 +1,29 @@ +What: /sys/bus/hid/drivers/prodikeys/.../channel +Date: April 2010 +KernelVersion: 2.6.34 +Contact: Don Prince <dhprince.devel(a)yahoo.co.uk> +Descripts/checkpatch.plscription: + Allows control (via software) the midi channel to which + that the pc-midi keyboard will output.midi data. + Range: 0..15 + Type: Read/write +What: /sys/bus/hid/drivers/prodikeys/.../sustain +Date: April 2010 +KernelVersion: 2.6.34 +Contact: Don Prince <dhprince.devel(a)yahoo.co.uk> +Description: + Allows control (via software) the sustain duration of a + note held by the pc-midi driver. + 0 means sustain mode is disabled. + Range: 0..5000 (milliseconds) + Type: Read/write +What: /sys/bus/hid/drivers/prodikeys/.../octave +Date: April 2010 +KernelVersion: 2.6.34 +Contact: Don Prince <dhprince.devel(a)yahoo.co.uk> +Description: + Controls the octave shift modifier in the pc-midi driver. + The octave can be shifted via software up/down 2 octaves. + 0 means the no ocatve shift. + Range: -2..2 (minus 2 to plus 2) + Type: Read/Write diff -X /opt/scripts/diff-exclude.txt -Npaur a/drivers/hid/hid-core.c b/drivers/hid/hid-core.c --- a/drivers/hid/hid-core.c 2010-04-22 18:52:46.445384754 +0100 +++ b/drivers/hid/hid-core.c 2010-04-25 19:10:31.317248975 +0100 @@ -1297,6 +1297,7 @@ static const struct hid_device_id hid_bl { HID_USB_DEVICE(USB_VENDOR_ID_BELKIN, USB_DEVICE_ID_FLIP_KVM) }, { HID_USB_DEVICE(USB_VENDOR_ID_CHERRY, USB_DEVICE_ID_CHERRY_CYMOTION) }, { HID_USB_DEVICE(USB_VENDOR_ID_CHICONY, USB_DEVICE_ID_CHICONY_TACTICAL_PAD) }, + { HID_USB_DEVICE(USB_VENDOR_ID_CREATIVELABS, USB_DEVICE_ID_PRODIKEYS_PCMIDI) }, { HID_USB_DEVICE(USB_VENDOR_ID_CYPRESS, USB_DEVICE_ID_CYPRESS_BARCODE_1) }, { HID_USB_DEVICE(USB_VENDOR_ID_CYPRESS, USB_DEVICE_ID_CYPRESS_BARCODE_2) }, { HID_USB_DEVICE(USB_VENDOR_ID_CYPRESS, USB_DEVICE_ID_CYPRESS_BARCODE_3) }, diff -X /opt/scripts/diff-exclude.txt -Npaur a/drivers/hid/hid-ids.h b/drivers/hid/hid-ids.h --- a/drivers/hid/hid-ids.h 2010-04-22 18:52:46.455385039 +0100 +++ b/drivers/hid/hid-ids.h 2010-04-25 19:10:31.319248829 +0100 @@ -147,6 +147,9 @@ #define USB_DEVICE_ID_CODEMERCS_IOW_FIRST 0x1500 #define USB_DEVICE_ID_CODEMERCS_IOW_LAST 0x15ff +#define USB_VENDOR_ID_CREATIVELABS 0x041e +#define USB_DEVICE_ID_PRODIKEYS_PCMIDI 0x2801 + #define USB_VENDOR_ID_CYGNAL 0x10c4 #define USB_DEVICE_ID_CYGNAL_RADIO_SI470X 0x818a diff -X /opt/scripts/diff-exclude.txt -Npaur a/drivers/hid/hid-prodikeys.c b/drivers/hid/hid-prodikeys.c --- a/drivers/hid/hid-prodikeys.c 1970-01-01 01:00:00.000000000 +0100 +++ b/drivers/hid/hid-prodikeys.c 2010-05-05 16:18:08.896362471 +0100 @@ -0,0 +1,970 @@ +/* + * HID driver for the Prodikeys PC-MIDI Keyboard + * providing midi & extra multimedia keys functionality + * + * Copyright (c) 2009 Don Prince <dhprince.devel(a)yahoo.co.uk> + * + * Controls for Octave Shift Up/Down, Channel, and + * Sustain Duration available via sysfs. + * + */ + +/* + * This program is free software;

[alsa-devel] [PATCH 1/2] snd-maestro3: Make hardware volume buttons an input device (rev2)
by Hans de Goede 07 May '10

07 May '10

While working on the sound suspend / resume problems with my laptop I noticed that the hardware volume handling code in essence just detects key presses, and then does some hardcoded modification of the master volume based on which key is pressed. This made me think that clearly the right thing to do here is just report these keypresses to userspace and let userspace decide what to with them. This patch adds a Kconfig option which when enabled reports the volume buttons as keypresses using an input device. When enabled this option also gets rid of the ugly direct ac97 writes from the tasklet, the ac97lock and the need for using a tasklet in general. As an added bonus the keys now work identical to volume keys on a (usb) keyboard with multimedia keys, providing visual feedback of the volume level change, and a better range of the volume control (with a properly configured desktop environment).

[alsa-devel] SPDIF out with HDA/Conexant 20561?
by pl bossart 06 May '10

06 May '10

Has anyone had any luck enabling S/PDIF output with the Conexant 20561/ctx5051? On my Lenovo W500 I see a digital output device, I can play on it but I can't hear any sound on my receiver. There was a patch by Takashi earlier this year to correct a wrong nodeID (03b515c45e2a93331d2ac9dc1c16440f7fa313ec, ALSA: hda - Fix SPDIF output widget for Cxt5051 codec), so I figure some amount of testing has been done already? I wonder if this comes from a non-initialized pin configuration as reported in /proc/asound/card0/codec#0?

[alsa-devel] [PATCH] ASoC: tlv320dac33: Use codec defaults for LOM/LOP and DAC power
by Peter Ujfalusi 06 May '10

06 May '10

Do not change the codec defaults for the following registers: 0x40, 0x41: Line output gains, do not use amplification 0x42: LOM/LOP Voltage hold, and selection 0x44: LOM inversion control It has been found, that the values configured to these registers can cause amplification, which can make the output of DAC33 distorted. The codec reset values are considered safe in all environmnts. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- If there is a need for user control over these, than additional kcontrols can be invented for the settings. But sorting out the meaning, and naming of such controls could take considerable time. At the moment, it is safer to use the codec defaults for these instead of the original values. sound/soc/codecs/tlv320dac33.c | 11 ----------- 1 files changed, 0 insertions(+), 11 deletions(-) diff --git a/sound/soc/codecs/tlv320dac33.c b/sound/soc/codecs/tlv320dac33.c index 68b7ccb..ad5e263 100644 --- a/sound/soc/codecs/tlv320dac33.c +++ b/sound/soc/codecs/tlv320dac33.c @@ -303,21 +303,10 @@ static void dac33_init_chip(struct snd_soc_codec *codec) /* C : (defaults) */ dac33_write(codec, DAC33_DAC_CTRL_C, 0x00); - /* 64-65 : L&R DAC power control - Line In -> OUT 1V/V Gain, DAC -> OUT 4V/V Gain*/ - dac33_write(codec, DAC33_LDAC_PWR_CTRL, DAC33_LROUT_GAIN(2)); - dac33_write(codec, DAC33_RDAC_PWR_CTRL, DAC33_LROUT_GAIN(2)); - /* 73 : volume soft stepping control, clock source = internal osc (?) */ dac33_write(codec, DAC33_ANA_VOL_SOFT_STEP_CTRL, DAC33_VOLCLKEN); - /* 66 : LOP/LOM Modes */ - dac33_write(codec, DAC33_OUT_AMP_CM_CTRL, 0xff); - - /* 68 : LOM inverted from LOP */ - dac33_write(codec, DAC33_OUT_AMP_CTRL, (3<<2)); - dac33_write(codec, DAC33_PWR_CTRL, DAC33_PDNALLB); /* Restore only selected registers (gains mostly) */ -- 1.7.1

[alsa-devel] [PATCHv2] ASoC: omap: Add basic audio support for Nokia RX-51/N900
by Jarkko Nikula 06 May '10

06 May '10

This patch adds support for integrated stereo speakers and digital microphone found on Nokia RX-51 hardware. This is a cut down version based on Maemo kernel sources and earlier patchset by Eduardo Valentin et al. http://mailman.alsa-project.org/pipermail/alsa-devel/2009-October/022033.ht… Signed-off-by: Jarkko Nikula <jhnikula(a)gmail.com> Cc: Eduardo Valentin <eduardo.valentin(a)nokia.com> Cc: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- This is for sound-2.6.git. This is independent and boot safe patch but audio codec doesn't probe without a few patches to arch/arm/mach-omap2/board-rx51-peripherals.c. See http://marc.info/?l=linux-omap&m=127290212826770&w=2 Some audio features would need more work and some, even being trivial to add, need more testing are there support for them in mainline. Thus this heavily simplified and little bit cleaned up version. --- sound/soc/omap/Kconfig | 10 ++ sound/soc/omap/Makefile | 2 + sound/soc/omap/rx51.c | 294 +++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 306 insertions(+), 0 deletions(-) create mode 100644 sound/soc/omap/rx51.c diff --git a/sound/soc/omap/Kconfig b/sound/soc/omap/Kconfig index f11963c..83be4a7 100644 --- a/sound/soc/omap/Kconfig +++ b/sound/soc/omap/Kconfig @@ -18,6 +18,16 @@ config SND_OMAP_SOC_N810 help Say Y if you want to add support for SoC audio on Nokia N810. +config SND_OMAP_SOC_RX51 + tristate "SoC Audio support for Nokia RX-51" + depends on SND_OMAP_SOC && MACH_NOKIA_RX51 + select OMAP_MCBSP + select SND_OMAP_SOC_MCBSP + select SND_SOC_TLV320AIC3X + help + Say Y if you want to add support for SoC audio on Nokia RX-51 + hardware.

[alsa-devel] [PATCH 1/2] powerpc/8610: add probing for individual DMA channels, not just DMA controllers
by Timur Tabi 05 May '10

05 May '10

A future version of the MPC8610 HPCD's ASoC DMA driver will probe on individual DMA channel nodes, so the DMA controller nodes' compatible string must be listed in mpc8610_ids[] for the probe to work. Also remove the "gianfar" compatible from mpc8610_ids[], since there is no gianfar (or any other networking device) on the 8610. Signed-off-by: Timur Tabi <timur(a)freescale.com> --- Kumar, the ASoC mainters are willing to pick up this patch, but they want an ACK from you first.

This is independent and boot safe patch but audio codec doesn't probe without a few patches to arch/arm/mach-omap2/board-rx51-peripherals.c. See http://marc.info/?l=linux-omap&m=127290212826770&w=2 Some audio features would need more work and some, even being trivial to add, need more testing are there support for them in mainline.

[alsa-devel] [PATCH] ASoC: tpa6130a2: TLV mapping for tpa6140a2
by Peter Ujfalusi 04 May '10

04 May '10

Both tpa6130a2, and tpa6140a2 is supported by the same driver, but the gain dB scaling is different on the amplifiers. Provide different mixer control for the chips with correct TLV mapping. User space will see: "TPA6130A2 Headphone Playback Volume" in case of 6130 "TPA6140A2 Headphone Playback Volume" in case of 6140 The way machine drivers are using this amplifier remained the same.

[alsa-devel] Playing multiple sounds at the same time
by Andreas Falkenhahn 04 May '10

04 May '10

Hi, I'm new to ALSA programming so please bear with me if the following question is all too obvious. I did some research on my question before but I didn't come across a clear answer. What I want to do is really simple: Playing multiple sounds in different formats at the same time. E.g. Sound 1: 12345 hz, 8-bit signed, mono Sound 2: 44100 hz, 16-bit unsigned, stereo Sound 3: 8000 hz, 8-bit unsigned, stereo Now I want to play sounds 1 to 3 at the same time. My question is now: Can ALSA do automatic mixing for me here or do I have to do the mixing on my own? In other words, can I simply feed all these three sound streams to ALSA or do I have to mix them into a fourth audio stream first and feeding this new fourth stream to ALSA then? Thanks, Andreas

[alsa-devel] safe support for rewind in ALSA
by pl bossart 04 May '10

04 May '10

All, I'd like to reopen a thread on concerns with the current implementation of rewind in ALSA. This was already discussed on the mailing list last year without any progress. (see http://thread.gmane.org/gmane.linux.alsa.devel/65759/focus=65773 and http://article.gmane.org/gmane.linux.alsa.devel/66902) The problem is that snd_pcm_rewind() allows in theory to go back to the next sample to be rendered. This however isn't possible on any existing hardware. DMAs do prefetch samples ahead of time, and output interfaces have FIFOs on top of this. This isn't too bad in the PC world with HDAudio, since the prefetching is limited. However in the embedded space it has become a headache. To reduce power consumption, most of the recent embedded interfaces do embed some local internal memory (5kB for TI's McBSP3, a lot more for others), and we should provide a means for driver developers to set a bound on how much can be rewound safely when power-saving features are enabled. Note that there already are a set of definitions for FIFOs, but they are either obsolete or no one uses them (actually HDAudio makes use of this value internally in azx_dev but doesn't export it). My suggestion would be to add a 'fifo' parameter to the runtime structure (so that it's visible to the core), let the driver developer fill the value in the .open routine, and use this parameter in rewind to prevent rewinding too much. This parameter would include both hardware FIFOs and DMA buffers. Comments welcome. - Pierre

[alsa-devel] asoc: fsl_dma_hw_free being called twice at end of playback
by Timur Tabi 04 May '10

04 May '10

In my 8610 ASoC driver, I'm seeing the DMA driver's .hw_free function being called twice whenever playback ends. I've added some printk's to demonstrate: snd_pcm_common_ioctl1:2543 snd_pcm_hw_free:543 soc_pcm_hw_free:761 c023983c fsl_dma_hw_free:720 substream=df029d00 dma_private=df440000 stream=0 snd_pcm_release_substream:2022 soc_pcm_hw_free:761 c023983c fsl_dma_hw_free:720 substream=df029d00 dma_private=df440000 stream=0 fsl_dma_close:759 substream=df029d00 dma_private=df440000 So the ioctl is being called only once, but the both snd_pcm_hw_free() and snd_pcm_release_substream() are calling the .hw_free function. Is this normal? I don't know how to handle this, other than to add some boolean to my private data structure that indicates whether the resources have been freed or not. -- Timur Tabi Linux kernel developer at Freescale

[alsa-devel] How to play a sine wave in alsa?
by Timo Schneider 04 May '10

04 May '10

Hello! I am trying to use alsa to play a sine wave in async mode. Everything seems to work fine, except what I am hearing is _not_ a sine wave. I am checking for XRUNs, but none occur, so I guess the problem is that I am supplying the wrong sample data to alsa. I want the tone only on one channel, that seems to work fine the way i do it, so i guess my assumptions on how the interleaved mode works are not completely wrong. Can anyone give me a hint on what I am doing wrong in the example program below? I already checked the example in tests/pcm.c but it didn't really help me. Regards, Timo Example Program (compile with cc test.c -o test -lasound): #include <math.h> #include <stdlib.h> #include <inttypes.h> #include <alsa/asoundlib.h> struct sound_settings { // alsa parameters snd_pcm_t *pcm_handle; snd_pcm_hw_params_t *hw_params; snd_pcm_sw_params_t *sw_params; snd_async_handler_t *pcm_callback; snd_pcm_uframes_t buffer_size; snd_pcm_uframes_t period_size; unsigned int sample_rate; char *sample_buffer; size_t sample_buffer_size; // user settings made in gui char *cardname; char *modename; int startfreq; int endfreq; int duration; int channels; // keep track of gnerated samples long int actsample; long int lastsample; }; struct sound_settings sdata; void generate_samples(struct sound_settings *sdata) { int i = 0; if (sdata->channels == 1) i=0; if (sdata->channels == 2) i=1; if (sdata->channels == 3) i=0; if (strcmp(sdata->modename, "Sine")==0) { while (i<(sdata->sample_buffer_size / 8)) { int samplerate = 44100; int freq = sdata->startfreq; double sample = sin(sdata->actsample * (double) 2*M_PI / ((double) samplerate / (double)freq)); int16_t rsamp = sample * 65535; sdata->actsample++; *(((int16_t*) (sdata->sample_buffer))+i) = rsamp; i += 2; } } } void MyCallback(snd_async_handler_t *pcm_callback) { snd_pcm_t *pcm_handle = snd_async_handler_get_pcm(pcm_callback); snd_pcm_sframes_t avail; struct sound_settings *sdata = (struct sound_settings*) snd_async_handler_get_callback_private(pcm_callback); avail = snd_pcm_avail_update(pcm_handle); if (avail == -EPIPE) { snd_pcm_prepare (pcm_handle); printf("Underrun occured\n"); } while (avail >= sdata->period_size) { generate_samples(sdata); snd_pcm_writei(pcm_handle, sdata->sample_buffer, sdata->period_size); avail = snd_pcm_avail_update(pcm_handle); } } void init_alsa(struct sound_settings *sdata) { int rc; // set some sound_settings data (i.e., sample_rate) to sensible defaults sdata->buffer_size = 1024; sdata->period_size = 64; sdata->sample_rate = 44100; // Open PCM device for playback rc = snd_pcm_open(&(sdata->pcm_handle), "default", SND_PCM_STREAM_PLAYBACK, 0); if (rc < 0) fprintf(stderr, "unable to open pcm device: %s\n", snd_strerror(rc)); // Allocate a hardware parameters object snd_pcm_hw_params_malloc (&(sdata->hw_params)); snd_pcm_hw_params_any(sdata->pcm_handle, sdata->hw_params); snd_pcm_hw_params_set_access(sdata->pcm_handle, sdata->hw_params, SND_PCM_ACCESS_RW_INTERLEAVED); snd_pcm_hw_params_set_format(sdata->pcm_handle, sdata->hw_params, SND_PCM_FORMAT_S16_LE); snd_pcm_hw_params_set_channels(sdata->pcm_handle, sdata->hw_params, 2); snd_pcm_hw_params_set_rate_near(sdata->pcm_handle, sdata->hw_params, &(sdata->sample_rate), NULL); snd_pcm_hw_params_set_buffer_size_near(sdata->pcm_handle, sdata->hw_params, &(sdata->buffer_size)); snd_pcm_hw_params_set_period_size_near (sdata->pcm_handle, sdata->hw_params, &(sdata->period_size), NULL); rc = snd_pcm_hw_params(sdata->pcm_handle, sdata->hw_params); if (rc < 0) fprintf(stderr, "unable to set hw parameters: %s\n", snd_strerror(rc)); // tell alsa we want to work asynchronously snd_pcm_sw_params_malloc(&(sdata->sw_params)); snd_pcm_sw_params_current(sdata->pcm_handle, sdata->sw_params); snd_pcm_sw_params_set_start_threshold(sdata->pcm_handle, sdata->sw_params, sdata->buffer_size - sdata->period_size); snd_pcm_sw_params_set_avail_min(sdata->pcm_handle, sdata->sw_params, sdata->period_size); rc = snd_pcm_sw_params(sdata->pcm_handle, sdata->sw_params); if (rc < 0) fprintf(stderr, "unable to set sw parameters: %s\n", snd_strerror(rc)); // Use a buffer large enough to hold two periods snd_pcm_hw_params_get_period_size(sdata->hw_params, &(sdata->period_size), NULL); sdata->sample_buffer_size = sdata->period_size * 8; // 2 bytes/sample, 2 channels, two periods sdata->sample_buffer = (char *) malloc(sdata->sample_buffer_size); generate_samples(sdata); // prepare dev so that we can write snd_pcm_prepare(sdata->pcm_handle); /* fill buffer with some data */ generate_samples(sdata); /* write first chunk of data */ rc = snd_pcm_writei(sdata->pcm_handle, sdata->sample_buffer, sdata->period_size); if (rc == -EPIPE) snd_pcm_prepare(sdata->pcm_handle); /* register callback */ rc = snd_async_add_pcm_handler(&(sdata->pcm_callback), sdata->pcm_handle, MyCallback, sdata); snd_pcm_start(sdata->pcm_handle); } int main(int argc, char **argv) { sdata.channels = 1; sdata.modename = "Sine"; sdata.startfreq = 220; sdata.actsample = 0; init_alsa(&sdata); static int i=0; while (i<1000000) { i++; sleep(1); } return 0; }

[alsa-devel] [PATCHv2 0/4] ASoC: tlv320dac33: Support for turning off codec
by Peter Ujfalusi 03 May '10

03 May '10

Hello, Changes since v1: - patch 1: Removed extra register writes - patch 4: - Let core to bring the codec to BIAS_OFF (set idle_bias_off) - dac33_set_bias_level only takes care of power and minimum initialization - PRE_DAPM widget event is replacing the dac33_pcm_pointer call to take care of the initialization needed before _every_ playback. There are few scenarios, which has to be taken care:: 1. Analog bypass caused BIAS_OFF -> BIAS_ON We need to power on the codec, and do the chip init, but we does not need to execute the playback related configuration 2. Playback caused BIAS_OFF -> BIAS_ON We need to power on the codec, and do the chip init, and also we need to execute the playback related configuration. 3. Playback start, while Analog bypass is on (BIAS_ON -> BIAS_ON) We need to execute the playback related configuration. The codec is already on. 4. Analog bypass enable, while playback (BIAS_ON -> BIAS_ON) Nothing need to be done. 5. Playback start withing soc power down timeout (BIAS_ON -> BIAS_ON) We need to execute the playback related configuration. The codec is still on. Since the power up, and the codec init is optimized, the added overhead in stream start is minimal. Withing this patch, the hard_power function is now only doing what it supposed to: only handle the powers, and GPIO reset line. The codec initialization and state restore has been moved out. --- Peter Ujfalusi (4): ASoC: tlv320dac33: Optimize power up, and restore ASoC: tlv320dac33: Revised module loading, and DAC33 ID read ASoC: tlv320dac33: Manage a pointer for snd_pcm_substream in private structure ASoC: tlv320dac33: Support for turning off the codec sound/soc/codecs/tlv320dac33.c | 235 ++++++++++++++++++++++------------------ 1 files changed, 129 insertions(+), 106 deletions(-)

[alsa-devel] [PATCHv3 0/2] ASoC: TWL4030: APLL/AIF ordering and DAPM updates
by Peter Ujfalusi 03 May '10

03 May '10

Hello, Changes since v2: apll_enable logic cleaned up. aif refcounting has been removed, aif handling simplified The new DAPM_OUTPUT and DAPM_INPUT widgets renamed Correct the APLL/AIF powering sequence. Also introducing DAPM outputs and input for keeping APLL/AIF enabled in case when no valid DAPM route selected during audio activity. The second patch removes the legacy OUTL/R. As a note: The APLL/AIF patch replaces the same patch in Liam's series. The OUTL/R removal can be applied after the OUTL/R reference has been removed from machine drivers (as in Lima's series). --- Peter Ujfalusi (2): ASoC: TWL4030: AIF/APLL fix in DAPM domain ASoC: TWL4030: Remove OUTL/R outputs sound/soc/codecs/twl4030.c | 86 ++++++++++++++++++++++++++++++------------- 1 files changed, 60 insertions(+), 26 deletions(-)

[alsa-devel] Changing volume of a single PCM channel
by Andreas Falkenhahn 03 May '10

03 May '10

Hi, how do I change the volume of single PCM channel with ALSA? I'm playing multiple sounds at the same time by opening a new channel for every sound using snd_pcm_open() and let PulseAudio do the mixing. Now assuming that I have allocated four channels using snd_pcm_open()... now I'd like to change the volume of the second channel, the other three channels' volume should not be affected. How can I do this? AFAICS, volume control is provided by the ALSA mixer interface but I don't seem to figure out how to connect the mixer with my PCM channels opened using snd_pcm_open(). Thanks for any help, Andreas

[alsa-devel] Reforming S3C I2S towards supporting I2Sv4
by Jassi Brar 02 May '10

02 May '10

Hello, I have prepared some patches that debug and modify the behaviour of extant S3C I2S support towards managing I2Sv4 controllers as well. Overall pic... For now the 'new' I2Sv4 CPU driver(s3c64xx-i2s-v4.c) is almost a copy of s3c64xx-i2s.c The driver will evolve as support for more features is added. Minor quirks in otherwise similar controllers are handled by defining a new field(feature) in 'struct s3c_i2sv2_info' that is meant to contain 1-bit flags for absence/presence of such quirks. The header with I2S register map and bit definitions has been copied to where the drivers are(sound/soc/s3c24xx/) since the header has nothing usable for platform code. Also, it will help avoid need for co-ordination between ASoC and S3C ARCH trees. For now, the header regs-s3c2412-iis.h is left intact but rendered useless by making ASoC drivers include the newly copied version of it (sound/soc/s3c24xx/regs-i2s-v2.h) Later the header could be dropped by patches to S3C PLAT tree. The patches apply against 'for-2.6.35' of http://www.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git Regards. Signed-off-by: Jassi Brar <jassi.brar(a)samsung.com>

[alsa-devel] [PATCH] Merge es1688 and es968 drivers
by Krzysztof Helt 01 May '10

01 May '10

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> The ESS ES968 chip is nothing more then a PnP companion for non-PnP audio chips. It was paired with non-PnP ESS' chips: ES688 and ES1688. The ESS' audio chips are handled by the es1688 driver in native mode. The PnP cards are handled by the ES968 driver in SB compatible mode. Move the ES968 chip handling to the es1688 driver so the driver can handle both PnP and non-PnP cards. The es968 is removed. Also, a new PnP id is added for the card I acquired (the change was tested on this card).

[alsa-devel] [PATCH 1/2] powerpc: add platform registration for ALSA SoC drivers
by Timur Tabi 01 May '10

01 May '10

An upcoming change in the architecture of ALSA SoC (ASoC) will require the MPC8610 HPCD's ASoC fabric driver to register as a standard platform driver. Therefore, we need to call platform_device_register_simple() from the board's platform code. Signed-off-by: Timur Tabi <timur(a)freescale.com> --- Kumar, the ASoC mainters are willing to pick up this patch, but they want an ACK from you first. Or, you could pick it up, since by itself it's harmless. arch/powerpc/platforms/86xx/mpc8610_hpcd.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/arch/powerpc/platforms/86xx/mpc8610_hpcd.c b/arch/powerpc/platforms/86xx/mpc8610_hpcd.c index 5abe137..66afff3 100644 --- a/arch/powerpc/platforms/86xx/mpc8610_hpcd.c +++ b/arch/powerpc/platforms/86xx/mpc8610_hpcd.c @@ -98,6 +98,9 @@ static int __init mpc8610_declare_of_platform_devices(void) /* Without this call, the SSI device driver won't get probed. */ of_platform_bus_probe(NULL, mpc8610_ids, NULL); + /* Register the platform device for the ASoC fabric driver */ + platform_device_register_simple("snd-soc-mpc8610-hpcd", 0, NULL, 0); + return 0; } machine_device_initcall(mpc86xx_hpcd, mpc8610_declare_of_platform_devices); -- 1.6.5

[alsa-devel] Relation between SND_PCM_IOPLUG_HW_PERIODS and SND_PCM_IOPLUG_HW_BUFFER_BYTES ?
by Stefan Schoenleitner 30 Apr '10

30 Apr '10

Hi, what is the relation between SND_PCM_IOPLUG_HW_PERIODS and SND_PCM_IOPLUG_HW_BUFFER_BYTES ? While SND_PCM_IOPLUG_HW_BUFFER_BYTES is the setting of the hardware buffer size, I'm not sure exactly what SND_PCM_IOPLUG_HW_PERIODS is. I suppose it is the number of periods the hardware buffer can take ? Hence the SND_PCM_IOPLUG_HW_PERIODS value is actually derived from the size of the hardware buffer ? Or is it rather the number of periods the ioplugin can receive at once ? Please enlighten me, cheers, Stefan

[alsa-devel] [PATCH 0/4] ASoC: tlv320dac33: Support for turning codec off
by Peter Ujfalusi 30 Apr '10

30 Apr '10

Hello, The following series adds support for turning the tlv320dac33 codec off in BIAS_STANDBY (and obviously in BIAS_OFF). Since the driver already had mechanics for supporting turned off codec in register writes, the needed changes are mainly in the BIAS/stream handling. As part of the series further optimization has been done to codec initialization, resume. The following scenarios has been tested, and verified (I think these are covering all cases): 1. Analog bypass caused BIAS_STANDBY -> BIAS_ON We need to power on the codec, and do the chip init, but we does not need to execute the playback related configuration 2. Playback caused BIAS_STANDBY -> BIAS_ON We need to power on the codec, and do the chip init, and also we need to execute the playback related configuration. 3. Playback start, while Analog bypass is on (BIAS_ON -> BIAS_ON) We need to execute the playback related configuration. The codec is already on. 4. Analog bypass enable, while playback (BIAS_ON -> BIAS_ON) Nothing need to be done. 5. Playback start withing soc power down timeout (BIAS_ON -> BIAS_ON) We need to execute the playback related configuration. The codec is still on. 6. Analog bypass enable withing soc power down timeout (BIAS_ON -> BIAS_ON) Nothing need to be done.

[alsa-devel] PCM multi A/V Sync bug on SMP system
by Keith Chew 30 Apr '10

30 Apr '10

Hi I have a SB Audigy Value card with 5.1 channel output. This is defined in my asound.conf: --------------------------- pcm.multi { type multi slaves { a.pcm "dmixerrear" a.channels 2 b.pcm "dmixerfront" b.channels 2 c.pcm "dmixercenter" c.channels 2 } bindings { 0.slave a 0.channel 0 1.slave a 1.channel 1 2.slave b 2.channel 0 3.slave b 3.channel 1 4.slave c 4.channel 0 5.slave c 5.channel 1 } } pcm.dmixerfront { type dmix ipc_key 1024 slave { pcm "hw:0,0" channels 2 } } pcm.dmixerrear { type dmix ipc_key 1025 slave { pcm "hw:0,1" channels 2 } } pcm.dmixercenter { type dmix ipc_key 1026 slave { pcm "hw:0,2" channels 2 } } --------------------------- Playing a video with "mplayer -ao alsa:device=multi ..." works fine, I can hear the 6-channel audio without any A/V sync issues. However, this is on a uniprocessor system. On an SMP system, the A/V sync gets out of sync from the start and drifts quite quickly. I have narrowed it down to the pcm_multi component giving this problem. On an SMP system, using just "mplayer -ao alsa ..." gives no A/V sync issues (because it is not using multi) on the 6 channels. Moreover, I have also tried "mplayer -ao alsa:device=dmixerfront ...", "mplayer -ao alsa:device=dmixercenter ..." and "mplayer -ao alsa:device=dmixerrear ...", all giving no A/V sync issues on the individual devices. Please advise how can I track down this problem in code, happy to make changes and test. PS: I need multi to work, so that I can add additional options like softvol on top of it. Regards Keith

[alsa-devel] How to retrieve the final data being played by HW
by Yu Hang 30 Apr '10

30 Apr '10

I'm studying ALSA lib and trying to write a plugin that can perform AEC function. I have to retrieve the data being played and use it as reference. I've read pcm_dmix.c and found dmix just simply mixes data into HW mmap buffer (destination buffer). My problem is, there might be several dmix instances, which doesn't know if there is other dmix instance. So how can I know the mixed data is exactly the data being played. For example, the 1st instance had mixes the data into destination buffer, but 2nd instance haven't complete the mix operation. Would the data in destination buffer be playing by HW? Or there is some mechanism to guarantee the data will be played after all mix operation is done.

[alsa-devel] asoc: problem with snd_soc_dai_set_fmt()
by Timur Tabi 30 Apr '10

30 Apr '10

There is a problem with snd_soc_dai_set_fmt(): int snd_soc_dai_set_fmt(struct snd_soc_dai *dai, unsigned int fmt) { if (dai->driver && dai->driver->ops->set_fmt) return dai->driver->ops->set_fmt(dai, fmt); else return -EINVAL; } Let's say the DAI driver has not defined a .set_fmt() function. This means that if the fabric driver does this: ret = snd_soc_dai_set_fmt(cpu_dai, machine_data->dai_format); if (ret < 0) { dev_err(dev, "could not set CPU driver audio format\n"); return ret; } It's going to think that the DAI driver *rejected* the DAI format. What this means is that I cannot make this function optional. I have to define this function in my CPU driver. May I propose this: int snd_soc_dai_set_fmt(struct snd_soc_dai *dai, unsigned int fmt) { if (dai->driver && dai->driver->ops->set_fmt) return dai->driver->ops->set_fmt(dai, fmt); else return 0; } -- Timur Tabi Linux kernel developer at Freescale

[alsa-devel] Wrote MIDIcat program, to connect ALSA MIDI to standard input/output
by Josh Lehan 30 Apr '10

30 Apr '10

Hi! A few months ago, I posted about a program to send untimed MIDI data to the ALSA sequencer. Using amidi(1) wasn't acceptable, since it only talks to "RawMIDI" devices. Using aplaymidi(1) wasn't acceptable either, because it required .MID files, and I simply wanted to send untimed MIDI data, similar to what would be produced if you hooked up a hardware MIDI keyboard and just started playing. I needed something more general, that would simply connect to the ALSA sequencer, and let me send arbitrary MIDI bytes to a sequencer destination of my choice. Unfortunately, no program existed that would simply do this. I'm pleased to announce that I've written such a program, It's called MIDIcat, as it works on the same principle as "cat" and other similar programs (Netcat, and so on). It hooks up standard input, and standard output, to the ALSA sequencer. This makes it easy to pipe data around. It's an ALSA sequencer client. Any data that is received on standard input will be forwarded into ALSA. You can choose another client as a destination, or you can just start the program passively and use ALSA's "subscription" mechanism to route the data later. Similarly, any MIDI data that comes from ALSA, will be forwarded along, and provided on standard output. This makes it easy to make many small "one-liner" command lines that are useful for testing and playing around with MIDI data in general. As an example, this plays Middle C: echo "90 3C 7F" | midicat --hex --port "TiMidity" The --hex option makes things more human-readable: standard input and output are hex digits, separated by spaces, instead of just raw binary data. The --port option has the usual ALSA sequencer meaning. Change it to target your synthesizer (I'm using the TiMidity softsynth). Here's another example for output (both of these commands block, so run them in two separate terminal windows): midicat --verbose --hex vkeybd --addr 129:0 The --verbose option prints out some more useful information at startup, such as the ALSA sequencer client:port number it got. That can later be passed into another program, such as vkeybd. If you play notes with vkeybd, you see the corresponding MIDI data appear on standard output. Standard input and standard output can both run at the same time (it's multithreaded). Here's some more elaborate examples: MIDI "panic button", sends "All Sound Off" to each channel: perl -e 'use bytes;for($i=0;$i<16;$i++){print chr(176+$i).chr(120).chr(0);}' | midicat --port "TiMidity" Another MIDI "panic button", sends individual "Note Off" commands: perl -e 'use bytes;for($i=0;$i<16;$i++){for($j=0;$j<128;$j++){print chr(128+$i).chr($j).chr(127);}}' | midicat --delay 10 --port "TiMidity" The --delay option inserts a slight delay between each MIDI command, to avoid flooding ALSA with too much data at once. Here's a fun one, sending random data into the MIDI subsystem and seeing what happens. DO NOT run this on a real synthesizer, there's the risk of composing a random SysEx command that could mess up your settings! It's fun to watch with aseqview(1): aseqview & cat /dev/urandom | midicat --delay 500 --port "MIDI Viewer" If you sent random data to a device that plays audio, you'll probably next want to use the "panic button" commands above...! Hope this illustrates some of the examples and possibilities. I'm working on writing some more documentation. The --help option is supported, there's a help output that shows you all of the available options. For now, the program is available here, on my Web server: http://krellan.com/midicat If you're interested, try it, and let me know what you think! Josh Lehan

[alsa-devel] My understanding of ALSA playback mechanism
by Yu Hang 30 Apr '10

30 Apr '10

Hi, I'm a newbie of ALSA. I've wrote some audio applications under Windows OS with DirectSound and Waveform Audio API. And I also have some knowledge about Sound Architecture of Windows Vista/Windows 7. All my experience about audio architecture was from Windows. I'm currently working on a ALSA plugin for AEC function. What I have to do is to retrieve audio data being played (after mixing) as reference to cancel the echo captured by MIC. According to my previous experience about Sound Architecture of Win7/Vista, the audio data is sending from OS component to my own component: no matter for capture or playback. All I have to do is just simply modify the input data and put them into output buffer. If my component is under OS mixer, the received audio data is after mixing. When I read source code of ALSA lib, I found the mechanism between Windows and ALSA lib are quite different. Following was my understanding about ALSA lib mechanism during playback. There is a hardware buffer. ALSA driver takes data from the buffer and sends it to HW. The driver also update the play position on the fly. dmix receive the data from application and mix them into a shared memory, and then copy it into hardware buffer. Each of dmix instance keep a pointer to indicate current mixing position which might different from other instance. [play pos] [1st mixed data] | | +----------------------------+ hardware buffer +----------------------------+ | [2nd mixed data] The figure shows, the data mixed from 1st dmix instance lasts to [1st mixed data] pos, and data mixed from 2nd dmix instance lasts to [2nd mixed data]. The buffer between [1st mixed data] and [2nd mixed data] contains only data of 2nd dmix instance, but it does not matter, ALSA just guarantees the data of 1st dmix instance can be mixed up before the [play pos] reaches [1st mixed data] pos. Of course the hardware buffer is not unlimited (it's a ring buffer), so before dmix mix data to hardware buffer, it has to check if there is enough space. Is my understanding of ALSA playback mechanism correct?

Do you mean that all applications must use pulse api instead of alsa-pulse plugin ? Did your test included those voip application which require low latency ? did your test only play one audio stream to the sound server ? Do those alsa application still work with "hw" device when pulseaudio is disabled ?

[alsa-devel] [PATCHv2 0/2] ASoC: TWL4030: APLL/AIF ordering and DAPM updates
by Peter Ujfalusi 29 Apr '10

29 Apr '10

Hello, Correct the APLL/AIF powering sequence. Also introducing DAPM outputs and input for keeping APLL/AIF enabled in case when no valid DAPM route selected during audio activity. The second patch removes the legacy OUTL/R. As a note: The APLL/AIF patch replaces the same patch in Liam's series. The OUTL/R removal can be applied after the OUTL/R reference has been removed from machine drivers (as in Lima's series). --- Peter Ujfalusi (2): ASoC: TWL4030: AIF/APLL fix in DAPM domain ASoC: TWL4030: Remove OUTL/R outputs sound/soc/codecs/twl4030.c | 91 ++++++++++++++++++++++++++++++++++---------- 1 files changed, 71 insertions(+), 20 deletions(-)

[alsa-devel] [PATCH] ASoC: TWL4030: AIF/APLL fix in DAPM domain
by Peter Ujfalusi 28 Apr '10

28 Apr '10

This patch orders the APLL and AIF power sequence in case of HiFi (audio in TWL4030 terms) playback. We also need to make sure that the AIF is running during playback/capture, when there is no valid DAPM route available. The apll and aif reference counting code has been lifted, and reused from Liam Girdwood's earlier patch. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- Some of the ideas (appl, aif refcounting) has been taken from Liam's patch: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-April/027217.html But I'm reusing the existing DAPM_SUPPLY widgets to handle the APLL and AIF enable. I have tested all possible scenarios, and the codec behaved correctly. The voice path was not verified due to missing HW, but that part has not been changed, so I expect no regressions related to that. sound/soc/codecs/twl4030.c | 91 ++++++++++++++++++++++++++++++++++---------- 1 files changed, 71 insertions(+), 20 deletions(-) diff --git a/sound/soc/codecs/twl4030.c b/sound/soc/codecs/twl4030.c index 2e025a3..816a995 100644 --- a/sound/soc/codecs/twl4030.c +++ b/sound/soc/codecs/twl4030.c @@ -123,7 +123,10 @@ struct twl4030_priv { struct snd_soc_codec codec;

by Liam Girdwood 27 Apr '10

27 Apr '10

Now that I'm back working full time on ASoC I'm going to manage the upstream branch for the OMAP platform and TI codecs. Mark will continue to manage the upstream for all other codecs, platforms and core. As usual, please CC both Mark and I on new ASoC patches. The OMAP upstream branch tracks Takashi's topic/asoc branch and is here :- git://git.kernel.org/pub/scm/linux/kernel/git/lrg/asoc-2.6.git #for-2.6.35 Thanks Liam -- Freelance Developer, SlimLogic Ltd ASoC and Voltage Regulator Maintainer. http://www.slimlogic.co.uk

[alsa-devel] [PATCH 11/11] ASoC: SMDK64XX: Switch to IISv4 CPU driver
by Jassi Brar 27 Apr '10

27 Apr '10

Switch the MACHINE driver to use IISv4 CPU dai. Remove BROKEN dependency now that we have proper CPU driver available. Also, disable build for SMDK6400, since the S3C6400 doesn't have IISv4 controller.

[alsa-devel] [PATCH 03/11] ASoC: S3C2412: I2S: Debug IMS field
by Jassi Brar 27 Apr '10

27 Apr '10

The IMS field of s3c2412/13 is essentially the same as that of s3c64xx. That is, the IISMOD[11] bit decides Master/Slave mode and IISMOD[10] bit selects source clock for signal generation. For that reason, remove improper defines for IISMOD[11:10] field mask and define two 1bit fields that can be set independent of each other. As a consequence, corresponding fields for PLAT_S3C64XX too get to use these new defines.

[alsa-devel] Control vs Device
by Jean-Yves Avenard 27 Apr '10

27 Apr '10

Hi. Currently maintaining the audio code on the MythTV project... Lately, I've had reports on issues by users when using digital audio. This for some reasons however fails, unless the device opened is something like : IEC958:{AES0: 0x06} When we are about to configure a digital audio stream, we do the equivalent of what iecset does. So I would have thought that our code should work under most circumstances... Then I started to suspect the code setting the IEC958_AES0_NONAUDIO bit. We always open the "default" controller like so: snd_ctl_open(&ctl, "default", 0) I thought that maybe the issue is that the "default" controller isn't the one to open. Is there a way, from the name of the device card ; to retrieve which controller is used? So before opening a specific ALSA audio device, I find the corresponding controller, set the flag non-audio on it and continue as usual.. I couldn't find any functions nor documentation that would help me achieve such results.. Any hints would be greatly appreciated... Thank you !! Jean-Yves

[alsa-devel] "Resource temporarily unavailable" while reading although poll returns POLLIN event
by Stefan Schoenleitner 27 Apr '10

27 Apr '10

Hi, I wrote a small application that opens both streams (i.e. capture and playback) of a PCM in non blocking (i.e. SND_PCM_NONBLOCK) mode. During device configuration I also set up the minimum number of frames to consider a PCM ready: --------------------------------------------------------------------------------- // when to consider the device to be ready for the next data transfer operation if ((ret=snd_pcm_sw_params_set_avail_min(handle, swparams, pcm_period_size))<0) { fprintf(stderr, "could not set avail_min: %s\n", snd_strerror(ret)); return NULL; } --------------------------------------------------------------------------------- As you can see it is set to the number of frames one period contains. In other words, each time there are at least that many frames available for reading on the capture device, we should get a POLLIN event when using poll(). On the other side we should get a POLLOUT event if that many frames can be written to the playback device. Then, later in my application, I use poll() on the fds of the PCM devices. As, according to the ALSA reference, poll events can be "mangeled", I use snd_pcm_poll_descriptors_revents() to "demangle" the events: --------------------------------------------------------------------------------- if ((ret=snd_pcm_poll_descriptors_revents(device_handle, &poll_fds[i], 1, &revents))<0) { fprintf(stderr, "could not snd_pcm_poll_descriptors_revents: %s\n", snd_strerror(ret)); exit(EXIT_FAILURE); } --------------------------------------------------------------------------------- After that, each time there was a POLLIN event, I am reading exactly one period from the capture PCM. On the other side, if there was a POLLOUT event, I am writing exactly one period to the playback PCM. While this works for a small number of periods (which is not always the same), I always end up with a "Resource temporarily unavailable" error when trying to read one period from the capture PCM: --------------------------------------------------------------------------------- demangled poll: POLLIN on capture device could not read from capture device: Resource temporarily unavailable --------------------------------------------------------------------------------- Since a POLLIN event only occurs after at least a full period is available for reading (as set up by snd_pcm_sw_params_set_avail_min() above) and I only read after a POLLIN event occured on the capture device fd, I really do not understand why I get the above error. So why does the above happen ? What am I doing wrong ? If it helps, I pasted the source code here so that you can view it nicely: http://pastebin.com/fCicqctq cheers, stefan

[alsa-devel] [patch] Fix headphone automute on Asus G50Vt laptops
by Solomon Peachy 26 Apr '10

26 Apr '10

On an Asus G50Vt laptop, plugging in the headphone jack mutes the internal speakers and the headphone jack too. Unplugging the jack unmutes both. This is a regression introduced between linux 2.6.27 and 2.6.28, and is still present in current alsa git sources. The root cause is that the g50v hooks in the hda-intel/patch_reaktek driver call an automute function for a different model (m51va). This patch has been sitting in the ALSA bug tracker for more than a year. Any chance int can finally be applied? https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4468 https://bugtrack.alsa-project.org/alsa-bug/file_download.php?file_id=2913&t… Even with this patch applied, there's still a secondary problem of the master 'mute' toggling both headphone and speaker outputs (I'm still poking around with hda_analyzer to figure out why) but even that's a vast improvement over no sound output at all when something's plugged in. Thanks! - Solomon -- Solomon Peachy pizza at shaftnet dot org Melbourne, FL ^^ (mail/jabber/gtalk) ^^ Quidquid latine dictum sit, altum viditur.

[alsa-devel] [PATCHv2 0/5] *** SUBJECT HERE ***ASoC: tlv320dac33: FIFO caused delay reporting and fixes
by Peter Ujfalusi 26 Apr '10

26 Apr '10

Hello, Changelog: - Calculated delay instead of msleep(2) in patch 1 - ns changed to us in patch 5 (in the macro for calculation) The main feature of this series is the FIFO caused delay reporting on the DAC33 codec.

[alsa-devel] ASoC - Support for multiple components
by Liam Girdwood 26 Apr '10

26 Apr '10

Currently ASoC is designed around a single CODEC and a single platform DMA engine in every sound card instance. This is fine for most embedded devices but current smart phone and STB designs are starting to outgrow this architecture. I'm currently working on adding ASoC support for multiple different CODECs and Platforms (DMA, Audio Engines) into a single sound card instance. This work will allow ASoC to support N CODECs and N platforms per sound card instance and also allow better integration of audio components from GSM MODEMs, BT, FM transceivers and PCM DSPs. I've now split each ASoC component (i.e. DMA, CODEC, DAI) into driver and device structures. This now means each ASoC component is a regular kernel device and can have private device data and platform_data. It should also provide better support for open firmware and flattened device tree. I've CC'ed folks on this mail who have either contributed or maintain ASoC architecture code. Please have a look at your architecture and test if you can. I only have access to OMAP and pxa3xx hardware and as such have only tested the changes on these two architectures only. I'd appreciated anyone else testing on the other architectures too. The changes are all purely mechanical to component registration and component private data only. However, some architectures (txx9, imx, s3c) required some extra effort to use the device model as they had (to varying degrees) coupled their DMA and DAI code more tightly. The fsl platform also required extra work around the open firmware interface. Grant/Timur do we still need soc-of-simple now that all components are regular devices ? The code is in my topic/multi-component branch here :- git://git.kernel.org/pub/scm/linux/kernel/git/lrg/asoc-2.6.git It's currently a patch for each component for easier review atm but will be rebased into a single commit when it's ready for upstream so it won't break bisect. If the testing can be done quickly then we can go for 2-6.35 otherwise we are looking at 2.6.36.

[alsa-devel] [PATCH 1/2] snd-maestro3: Make hardware volume buttons an input device
by Hans de Goede 22 Apr '10

22 Apr '10

While working on the sound suspend / resume problems with my laptop I noticed that the hardware volume handling code in essence just detects key presses, and then does some hardcoded modification of the master volume based on which key is pressed. This made me think that clearly the right thing to do here is just report these keypresses to userspace as keypresses using an input device and let userspace decide what to with them. This patch does this, getting rid of the ugly direct ac97 writes from the tasklet, the ac97lock and the need for using a tasklet in general. As an added bonus the keys now work identical to volume keys on a (usb) keyboard with multimedia keys, providing visual feedback of the volume level change, and a better range of the volume control (with a properly configured desktop environment).

From: Pedro Lopez-Cabanillas <pedro.lopez.cabanillas(a)gmail.com> snd_seq_parse_address() uses strncmp() to compare the client name in the string argument with the existing clients, until it finds one name matching the same leading characters. This may produce wrong results when there are two sequencer clients with similar names. For instance, the following procedure produces a wrong result: 1. start KMidimon (http://kmidimon.sf.net) $ kmidimon & -->results: Client 128 : "KMidimon" [User] 2. start KMid (http://kmid2.sf.net) $ kmid & -->results: Client 129 : "KMid" [User] 3. try to subscribe the output port of KMid to KMidimon $ aconnect KMid:0 KMidimon:0 --> results: Client 128 : "KMidimon" [User] Port 0 : "KMidimon" (RWe-) Connecting To: 20:0, 128:0 Connected From: 0:1, 128:0 128:0 becomes subscribed to itself.

Actually, IME it's probably as easy to just backport current ASoC to 2.6.29 if you're doing anything non-trivial - the backport is very straightforward for most platforms and the benefits of the enhancements in ASoC are well worth the effort.

[alsa-devel] caps-bug (fwd)
by Tim Goetze 22 Apr '10

22 Apr '10

Hello alsa team, please find attached a bug report I received a short while ago. The finder isolated the problem on his own. It turned out that the "type equal" pcm slave ran the stereo plugin "Eq2x2" without connecting all of the plugin's input and output ports. This is in violation of ladspa.h, which mandates: """The plugin may assume that all its input and output ports have been connected to the relevant data location (see the `connect_port()' function below) before it is asked to run.""" -> http://www.ladspa.org/ladspa_sdk/ladspa.h.txt Cheers, Tim PS: not subscribed to this list. ---------- Forwarded message ---------- Subject: caps-bug From: x(a)y.z To: tim(a)quitte.de Date: Tue, 13 Apr 2010 11:35:41 +0200 Dear caps team, I'm using caps and the alsaequal alsa plugin together in my application. There is a failure when i want to close the pcm stream (snd_pcm_close). I'm working on redhat enterprise 5.4.

Bringing the outcome of a recent off-list push to get asihpi driver (for AudioScience soundcards) into kernel sources back on list: Takashi Iwai wrote: > Now merged, and finally moved to sound git tree. > > Your driver will appear in tomorrow's linux-next tree if no merge > problem occurs. > > Thanks for your efforts! Thank you very much for your help and patience, and work in merging many patches. It has been quite a long road. Looking back at my local history, the first commit of asihpi.c creating our local patches to alsa was on 2003-05-28, and Takashi's first commit to alsa-driver git on 2005-08-26. best regards Eliot Blennerhassett AudioScience Inc.

Or > can I change some of the input amplifiers? I do not have access to datasheets and I am not an ALSA expert either. So I am not sure what the reason for the noise could be. Perhaps you could try adding mixers? I have read somewhere that the T410s has some sort of noise cancelation capabilities. I do not know if they are hard- or software based. Perhaps you could play with the GPIOs and see if that changes anything (e.g. enables noise cancelation). Best Regards Jens Taprogge

[alsa-devel] [PATCH] snd-maestro3: Make hardware volume buttons an input device
by Hans de Goede 21 Apr '10

21 Apr '10

While working on the sound suspend / resume problems with my laptop I noticed that the hardware volume handling code in essence just detects key presses, and then does some hardcoded modification of the master volume based on which key is pressed. This made me think that clearly the right thing to do here is just report these keypresses to userspace as keypresses using an input device and let userspace decide what to with them. This patch does this, getting rid of the ugly direct ac97 writes from the tasklet, the ac97lock and the need for using a tasklet in general. As an added bonus the keys now work identical to volume keys on a (usb) keyboard with multimedia keys, providing visual feedback of the volume level change, and a better range of the volume control (with a properly configured desktop environment).
