[alsa-devel] Problems with snd-hda-intel ALC1200 on msi gt725-212us laptop Only one speaker works and headphones do not mute laptop sound
by Tony Rao 31 Aug '09

31 Aug '09

msi gt725-212us Codec: Realtek ALC1200 This laptop has 4.1 sound. Sound is only coming out of subwoofer. When I plug in headphones sounds still comes out of subwoofer, but headphones work perfectly. http://www.alsa-project.org/db/?f=e95a9401ebfa6cb0133b11fc1482ea115f766d5e Thanks, Tony R

[alsa-devel] Error enabling dmix with ALSA
by ruchi sirauthiya 30 Aug '09

30 Aug '09

Hi, I am trying to enable a software mixer (using ALSA and dmix) on an OMAP3 based embedded target board using the twl4030 codec. When I try to play audio using the command, # aplay -D playback rec.wav I am getting the following error: ALSA lib pcm_direct.c:1098:(snd_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0' ALSA lib pcm_dmix.c:943:(snd_pcm_dmix_open) unable to initialize poll_fd aplay: main:546: audio open error: No such file or directory The contents of my /etc/asound.conf is given below. pcm.playback { type dmix ipc_key 2048 ipc_key_add_uid true ipc_gid 1 slave { rate 44100 pcm hw:0 } } I have tested it on two kernel versions, 2.6.22 and 2.6.29, but it fails on both. Playback and recording works fine if -D option is not provided. I also tried configuring ALSA (dmix) with a different configuration file which is given in the following link: http://amarok.kde.org/wiki/Setting_up_Dmix_for_ALSA # aplay -D plug:ossmix /mnt/Audio1_1.wav ALSA lib pcm_direct.c:1098:(snd_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0' ALSA lib pcm_dmix.c:943:(snd_pcm_dmix_open) unable to initialize poll_fd aplay: main:546: audio open error: No such file or directory But as you can see the same error turns up again. The topic discussed in the following link (a similar issue) suggests that it is unable to open a second timer. http://osdir.com/ml/linux.distributions.crux.general/2005-11/msg00134.html What could be the cause of this error? Is the above error related to my ALSA configuration (for dmix) or is it related to the sound hardware (or driver)? Do I need to patch the kernel or ALSA for using dmix? Please help me resolve this issue. Let me know if any more setup info is required. Thanks and Regards, Ruchi Sirauthiya.

[alsa-devel] ASoC DAI on Atmel AT32AP7000
by Christos Nikolaou 30 Aug '09

30 Aug '09

Hi, Up to 2.6.28 the ASoC framework was working on AT32AP7000 Atmel platform. Now I try to recompile it on 2.6.31-rc8 and I get Advance Linux Sound Architecture Driver Version 1.0.20. No device for DAI atmel-ssc0 No device for DAI atmel-ssc1 No device for DAI atmel-ssc2 whereas the ssc devices are properly (as in 2.6.28) initialized ssc ssc.0: Atmel SSC device at 0xffe1c00 (irq 10) ssc ssc.1: Atmel SSC device at 0xffe2000 (irq 11) ssc ssc.2: Atmel SSC device at 0xffe2400 (irq 12) It looks that this message comes from snd_soc_register_dai in soc-core.c if (!dai->dev) printk(KERN_WARNING "No device for DAI %s\n", dai->name); it seems for some reason it thinks there is no device in dai->dev Unless I'm mistaken, that is being called from sound/soc/atmel/atmel_ssc_dai.c after some modifications done by broonie on these files according to http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;… . Is there anything that can be done to rectify this? Regards, Christos

[alsa-devel] ASoC: at91sam9260-PCM1808/TAS5709-based board driver
by Pedro Sanchez 28 Aug '09

28 Aug '09

Hello, I have to develop a driver for a custom board based on the at91sam9260 with a PCM1808/TAS5709 chipset combo. I am addressing the PCM1808 first because it is a simpler device. Since I'm new to ASoC I'm looking for some help in this list on how to go about writing this driver. So far I have identified two files that I need to work on (other than the needed kconfig modifications). First is the codec driver at sound/soc/codecs/PCM1808.[c|h] which is based on the existent pcm3008 driver; I believe I'm fine with this. The second file is the machine driver at sound/soc/atmel/myBoard.c. I'm using sam9g20_wm8731.c as reference, on which I believe I found a typo which I reported in a separated e-mail. So my first question is, is this two-files step the right approach? am I in the right track? I'm using the 2.6.30 kernel. Other questions will come and I hope I will get some cycles from you to help me direct my work. Of course I'll be glad to submit my driver work for inclusion in the kernel if it proves useful. Regards, -- Pedro

[alsa-devel] Audio capture not working with AIC23/McBSP1 on OMAP3517

Hi, I am trying to capture audio through LineIn on my OMAP3517 EVM, using AIC23 codec and McBSP1, and getting the following error: arecord: pcm_read:1529: read error: Input/output error Playback is working fine using the same combination. I have tried using another instance of AIC23 codec which uses McBSP2 and both playback & capture works fine there. Has anyone faced this issue before? Any suggestions? Regards, Anuj Aggarwal

[alsa-devel] SNDRV_PCM_TRIGGER_STOP and audio still queued in the driver
by Jon Smirl 28 Aug '09

28 Aug '09

In the mpc5200 driver I'm receiving SNDRV_PCM_TRIGGER_STOP with audio still queued. I noticed this in an app that uses a 2MB ALSA buffer. It is filling the 2MB buffer which starts playing. After the buffer is filled I receive the STOP. This STOP comes before the hardware has a chance to play all of the music. There is still about twenty seconds of music in the driver buffer waiting to be played. How is this supposed to work? -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] [PATCH 1/1] sound: usb-audio: support for Digidesign Mbox 2
by Damien Zammit 27 Aug '09

27 Aug '09

Provides magic boot sequence which activates the device, must loop until device is ready, (returns status bytes). Provides extra magic to set the device into 24 bit mode. -Playback works @ 24-bit -MIDI I/O works -Capture is untested, but PCM stream is active -S/PDIF (RCA) I/O is untested, but lights activate on the device S/PDIF mode works by setting the required flag in usbaudio.c. I think the device can't do both simultaneously, since different altsettings are required to set it. Remaining issues: 1) Double check endianess of 24 bit capture. 2) Check duplex stability 3) Tell ALSA to correctly detect S24_3BE on the device. Currently, speaker-test assumes S16_LE and won't allow S24_3BE mode, but jackd 0.116-2 detects and plays S24_3BE ? 4) Create a kernel module switch to select spdif/analogue I/O Playback sample format : S24_3BE MIDI format : MIDIMAN protocol Signed-off-by: Damien Zammit <damien.zammit(a)gmail.com> diff --git a/sound/usb/usbaudio.c b/sound/usb/usbaudio.c index 43d7d88..3060941 100644 --- a/sound/usb/usbaudio.c +++ b/sound/usb/usbaudio.c @@ -943,7 +943,7 @@ static snd_pcm_uframes_t snd_usb_pcm_pointer(struct snd_pcm_substream *substream { struct snd_usb_substream *subs; snd_pcm_uframes_t hwptr_done; - + subs = (struct snd_usb_substream *)substream->runtime->private_data; spin_lock(&subs->lock); hwptr_done = subs->hwptr_done; @@ -2441,6 +2441,12 @@ static int parse_audio_format_i_type(struct snd_usb_audio *chip, struct audiofor fp->altsetting, sample_width, sample_bytes); break; } + + /* Digidesign Mbox 2 workaround: + * supports S24_3BE BIG ENDIAN */ + if (chip->usb_id == USB_ID(0x0dba, 0x3000)) + pcm_format = SNDRV_PCM_FORMAT_S24_3BE; + break; case USB_AUDIO_FORMAT_PCM8: pcm_format = SNDRV_PCM_FORMAT_U8; @@ -2550,13 +2556,20 @@ static int parse_audio_format_i(struct snd_usb_audio *chip, struct audioformat * switch (chip->usb_id) { case USB_ID(0x0763, 0x2003): /* M-Audio Audiophile USB */ - if (device_setup[chip->index] == 0x00 && + if (device_setup[chip->index] == 0x00 && fp->altsetting == 6) pcm_format = SNDRV_PCM_FORMAT_S16_BE; else pcm_format = SNDRV_PCM_FORMAT_S16_LE; break; - default: + + /* Digidesign Mbox 2 supports SPDIF 24 bit (havent tested endianess) */ + case USB_ID(0x0dba, 0x3000): + pcm_format = SNDRV_PCM_FORMAT_S24_3BE; + break; + + default: + snd_printdd("Format III detected, setting default S16_LE\n"); pcm_format = SNDRV_PCM_FORMAT_S16_LE; } } else { @@ -2655,6 +2668,8 @@ static unsigned char parse_datainterval(struct snd_usb_audio *chip, static int audiophile_skip_setting_quirk(struct snd_usb_audio *chip, int iface, int altno); +static int mbox2_skip_setting_quirk(struct snd_usb_audio *chip, + int iface, int altno); static int parse_audio_endpoints(struct snd_usb_audio *chip, int iface_no) { struct usb_device *dev; @@ -2700,13 +2715,19 @@ static int parse_audio_endpoints(struct snd_usb_audio *chip, int iface_no) stream = (get_endpoint(alts, 0)->bEndpointAddress & USB_DIR_IN) ?

[alsa-devel] ALSA default buffer sizes (recent now being subscribed with correct address... hopefully)
by Manuel Jander 26 Aug '09

26 Aug '09

Hi there, I'm somewhat upset because audacious does not work with my AU8830. The problem is that audacious never calls any function that would give any clue about the desired buffer size. So my AU8830 ends up with 32 periods, 1 byte each. Great ! I'm not going to blame the author of that driver :P ... but: The question is, who is the entity deciding those default values ? Other soundcards seem to get reasonable defaults, but the AU8830 does not. So I would like to fix that, but I want to do that at the right place. Best Regards, and many thanks for any hint.

Problem: Alsa randomly crashes after ~10 hours of use; this varies from 2 to 20 hours. Symptoms: Sound stops while media is playing (in web browser, or mplayer), or convulses sporatically. The issue is not always reproducible (i.e I can reproduce the result when I want), but it is perisistant.

Try rather with the snapshot tarball in ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna… The version you tried isn't the latest one. > It's diff between patched version( patch_realtek_new.c ) and unpatched: Make a patch with diff -u option (and better with -p, too). thanks, Takashi

[alsa-devel] [PATCH] ASoC: SDP3430: Fix TWL GPIO6 pin mux request
by Candelaria Villareal, Jorge 25 Aug '09

25 Aug '09

Fix the write to PMBR1 register through I2C. Also, the constant which holds the value to write is now called TWL4030_GPIO6_PWM0_MUTE. This name is based on TRM to avoid confusion.
