[alsa-devel] USB microphone not working. No sound, although device visible.
by Shapeshifter 23 Jun '09

23 Jun '09

Hi there. Following problem, details below: PROBLEM: I can't record anything using the microphone which is integrated into my USB webcam. The cam shows up as a device, and I can adjust the only available mixer which is for <Mic> in [Capture]. It's not muted and it's maxed out. DETAILS and PASTES: Alsa-info output: http://www.alsa-project.org/db/?f=f12fd357bc269d27ebdb4b5d562227bbe22a1086 You might notice the device comes up as [default]. If I run... $ arecord -Dplughw:1,0 -f cd -vv /dev/null or $ arecord -Ddefault -f cd -vv /dev/null then it out puts a lot of stuff (both the same) which I pasted in the below pastebin, but at the bottom it doesn't show any #'s and %'s to indicate the volume. The blue light on the webcam also turns on. If I save to a file instead of /dev/null and aplay it, it's just silence. Here's the output from the above command: http://pastie.org/521697 Although if I run $ arecord -Dhw:1,0 -f cd -vv /dev/null then it fails with: -> Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo -> arecord: set_params:984: Channels count non available" I made a screenshot illustrating that everything is turned up and unmuted: http://omploader.org/vMXZldg ALREADY TRIED: - Switching the two devices so that 0 becomes the webcam and 1 the intel-hda through modprobe.conf but that had no other effect other than the switching. - Playing a lot with the device, muting, triplechecking volumes etc. etc. - Trying recording something in audacity. First time, the light goes on but it doesn't record, on subsequent tries, audacity spits an error stating "error opening sound device". - Trying it in linphone, light turns on, but other party can't hear anything. Any ideas how to fix hits? Btw, it used to work in ubuntu 9.04 for some reason. Tried it on two Archlinux boxes, it's exactly the same on both. But everything works really, everything is very up to date (I'm sure ubuntu has older versions of stuff). Well, all the info is in the alsa-info link above. Hope I can work this out! Thanks for any input! Regards.

[alsa-devel] ASoC CODEC power management on reboot
by Ben Dooks 23 Jun '09

23 Jun '09

I've run into a problem where when the system reboots the audio starts playing random data. I suspect that this is due to the CODEC being left powered and when the during/after the reset process the GPIO lines which form the I2S bus are left floating. Should the ASoC (possibly DAPM) layer sort out powering down the CODEC before reboot, or should it be down to the codec or the mapping driver to do this? -- Ben Q: What's a light-year? A: One-third less calories than a regular year.

[alsa-devel] Please help in adding ams-delta support to ASoC
by Janusz Krzysztofik 23 Jun '09

23 Jun '09

Hi, I am trying to add sound support for ams-delta omap machine, yet without much success. Three years ago, Mark Underwood created an omap-alsa compatible driver that basically worked[1]. It was derieved from similiar driver for aic23 codec found on omap osk machine. It looks like Mark has never managed to finish his work. It's not clear for me if he has found that getting a working fullduplex sound is technically impossible on a voice modem codec, shared among modem and cpu, controlable only from modem side afaik, but I have decided to give it a try. Since Mark's initial work, omap-alsa framework has been depreciated in favour of soc-omap. API changes are so significant that Mark's code is rather not useable directly any more. However, I am trying to use it as a starting point, by comparing it against it's prototype osk/aic23 code. Following Mark, I am trying to derieve the new ams-delta sound driver from current asoc driver for omap osk9512. For codec part, I decided to base my work on much more simple ad73311 rather that tlv320aic23. Comparing Mark's code agaist it's osk/aic23 prototype, I can see the folowing significant changes: 1. rate tables/bitmaps found in hw_constraint_rates, snd_omap_alsa_playback and snd_omap_alsa_capture structures limited to 8kHz, 2. hardware related code found in codec_configure_dev(), codec_clock_on() and codec_clock_off() callback functions replaced with ams-delta hardware specific code that switches the codec DAI pins from modem chip to mcbsp cpu interface and back, 3. codec_set_samplerate() and all mixer related functions replaced with stubs. 4. the following McBSP register settings changes: - .xcr2 = XPHASE | XFRLEN2(OMAP_MCBSP_WORD_8) | - XWDLEN2(OMAP_MCBSP_WORD_16) | XDATDLY(0) | XFIG, + .xcr2 = XPHASE | XWDLEN2(OMAP_MCBSP_WORD_16) | XFRLEN2(0), - .srgr1 = FWID(DEFAULT_BITPERSAMPLE - 1), + .srgr1 = CLKGDV(0), - .srgr2 = GSYNC | CLKSP | FSGM | FPER(DEFAULT_BITPERSAMPLE * 2 - 1), + .srgr2 = GSYNC, - .pcr0 = CLKXP | CLKRP, /* mcbsp: slave */ I have found points 1. to 3. rather trivial to implement in new framework. Regarding point 4., it looks like detailed register settings are now done inside omap-mcbsp.c, based on machine specified format, so I have to find out what format should be specified for ams-delta. Please correct me if I am missing something. There was one more modification in Mark's code, addressing dma chaining problem on omap15xx hardware, but as far as I could see, the problem was already solved in the asoc omap framework. Initially, I based my work on ompenembedded provided linux-omap.git revision 90e758af52ba803cba233fabee81176d99589f09. The results were rather poor - total system hangup after first device access, with no single message. So I have switched to linux-2.6.30-rc5 and now I can safely access the device, however it does not work as expected. aplay and arecord wait forever, cat to/from /dev/dsp breaks with hardware error messgae. DMA interrput counters stay at 0. However, codec switching that I do from machine->ops->startup/shutdown seems working, as modem stops producing any sounds while the alsa device is in use and gets back thereafter. First of all, I'd like to make sure if my problem is related to my code only. As I am new in these areas, I would like to ask you if the omap asoc framework is stable enough to relay on. If yes, could you please look at my dirty code (attached) an give me some hints? I can provide you with more information if necessary. Regards, Janusz [1] http://www.earth.li/pipermail/e3-hacking/2006-April/000481.html

[alsa-devel] Indirect Callback with ack is called with no data
by Singaravelan Nallasellan 23 Jun '09

23 Jun '09

I am using indirect callback mechanism inside ack. I see that ack does not call my indirect callback pointer. Going through the code, I suspect that the appl_ptr is not being incremented and there is no data for the indirect callback to be called. After few acks, I get the indirect callback called. With aplay, I am able to play the wav file. But with flash, there is not data being sent to the driver. Please help me with any clues. Thanks in advance.

Hm, how about model=fujitsu-pi2515 or model=fujitsu-xa3530 option? Just a wild guess from the PCI SSID, though. Takashi

[alsa-devel] Noisy USB audio stream using MPlayer
by Eran Ben-Avi 23 Jun '09

23 Jun '09

Hi, I encountered some issue with my USB audio device and couldn't find any similar issue in previous mailing lists, any help will be appreciated. When playing an audio stream using MPlayer Ver1.0rc2-4.1.2 (tried different sample rates 44K, 48K and different files WAV , MP3) using my Creative SB0271 USB device on ARM based system(Marvell Kirkwood SoC) and kernel 2.6.22.18, I hear an interfering constant noise additionally to the original audio stream. At the beginning I heard this noise also when I used aplay(for WAV) but after I reinstalled the ALSA-LIB and ALSA-UTILS(version 1.0.14rc4), the aplay suddenly started to work smooth. I tested different USB audio device(AKM) but got same noisy results. Another piece of information I can provide is that increasing the CPU utilization eliminates the noise completely - maybe a timing issue ??? Any ideas ? Thanks, Eran.

[alsa-devel] [PATCH] ASoC: TWL4030: Correct bypass event for voice sidetone
by Lopez Cruz, Misael 23 Jun '09

23 Jun '09

Event for voice sidetone was being interpreted as an analog HiFi bypass event because VSTPGA register offset is less than ARXR2_APGA_CTL offset. Reordering the register checks allows to handle voice digital bypass event properly.

[alsa-devel] alc889
by Stefan Krastanov 22 Jun '09

Hi I would like to help (or at least help myself) with the creation of a model config for alc889. I'm not a sound developer. I'm using a laptop with alc889 based sound card. The reported pins are really messed up (it's hard not to use more profane expression). My laptop is Fujitsu-Siemens Amilo xi but the problems are the same as here: https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/71205 or here: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-October/011295.ht… namely: 1.- no jack sensing (extremely annoying - for two years allready) 2.- misnamed mixers in volume control for gnome or alsamixer (example: front instead of headphone) 3.- the volume-control potentiometer on the side of the laptop is not working 4.- I need to mute two different channel at the same time (center and LFE) to mute one physical output (build-in sub-woofer) 5.- A great deal of other small annoyances destroying the user experience I'm using model 3stack-dig and the optical output is working (at least is lighted up - I do not have the hardware to check it) My questions are: - What I need to do, to create new model option based on 3stack-dig with different pin mapping? - Is it possible that my present configuration (3stack-dig) is using pins that should not be used? I'm asking in search of an explanation of problem 4. - What I need to do to rename the controls in alsamixer? - What to do to repair jack sensing? - that's the most important of all - What to do to repair the potentiometer for volume control? I have seen that hda-analyser can create diff files, but where should they be used. (And why is hda-analyser not working - I was forced to use http://ubuntuforums.org/showpost.php?p=7227626&postcount=33. Is it that much to expect working tools on the official website. I understand that small bug will always exist, but that one is there for at least 10 months) I won't be surprised if many of my questions are answered in the documentation, but I was unable to find anything useful. It would be enough to point me a place to start reading. I know you guys are working hard and you have done great things, but it's really hard to find something in the documentation(which is occasionally quite old) Best regards and thank you for the great work Stefan Krastanov
