[alsa-devel] alsactl init - implementation and more..
by Jaroslav Kysela 14 Aug '08

14 Aug '08

Hi, some developers probably already noted, I commited to alsactl utility (alsa-utils package) initial implementation of soundcard initialization stuff aka 'alsactl init'. The basic idea was to "reuse" nice udev configuration style and modify it to ALSA purposes. I hope that I ended up with a syntax which is easy understandable and configuration can be created with minimal effort. Please, look to 'man 7 alsactl_init' for more details and to alsa-utils/alsactl/init directory for example files. Note that the runtime evaluation of commands can be modified using environment variables like udev does. Just try 'alsactl -E CMD=help init' or 'CMD=help alsactl init'. Hardware can be detected using sysfs. For older kernel, I'm plannig to add some compatibility layer to read at least ATTR{subsystem_vendor} and ATTR{subsystem_device} information from procfs (codec files). Also, a way to gather working configurations for specific hardware is required. A nice script alsa-info.sh is already in the alsa-driver package, so I just created a simple persistent "file" dabatase on www.alsa-project.org: http://www.alsa-project.org/cardinfo-db/ and modified alsa-info.sh to use this database for the contents upload by default. Developers can download whole database in a tar package to extract necessary information using command line text tools and use this database also for other purposes (HDA codec graphing and so). More ideas, corrections, opinions are welcome. Jaroslav ----- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc.

[alsa-devel] S24_LE Mode for USB Driver
by Charles Eidsness 13 Aug '08

13 Aug '08

Hi All, It looks like the parse_audio_format_i_type function at line 2369 of usbaudio.c (linux v2.6.23) doesn't support the case where bSubframeSize (fmt[5]) = 4 bytes and bBitResolution (fmt[6]) = 24 bits, which should correspond to a S24_LE (or BE) type. I'm developing a new USD DAC which supports this mode (24-bit sample in a 4 byte package). Right now Linux sends me S32_LE formated data, which is wrong. Would it be possible to expand this function to support S24_LE/BE? It would only require adding a few lines of code. Thanks! Charles

[alsa-devel] snd_assert() removal
by Rene Herman 13 Aug '08

13 Aug '08

Hi Takashi. Just see the snd_assert() removal. Much better as far as I'm concerned but just as a remark -- there's many combined ones of the form: diff --git a/sound/isa/cs423x/cs4236_lib.c b/sound/isa/cs423x/cs4236_lib.c index 33e9cf1..6a85fdc 100644 --- a/sound/isa/cs423x/cs4236_lib.c +++ b/sound/isa/cs423x/cs4236_lib.c @@ -967,7 +967,8 @@ int snd_cs4236_mixer(struct snd_wss *chip) int err; struct snd_kcontrol_new *kcontrol; - snd_assert(chip != NULL && chip->card != NULL, return -EINVAL); + if (snd_BUG_ON(!chip || !chip->card)) + return -EINVAL; card = chip->card; strcpy(card->mixername, snd_wss_chip_id(chip)); in there. Just thought I'd point that Andrew Morton has been pushing back on multiple conditions per regular BUG_ON()/WARN_ON() lately as they end up giving less useful information then split ones ("so what triggered?"). Just a remark as said but if you agree with him, maybe now is the best time to split them directly as well. Rene.

[alsa-devel] developing audio with ALSA

Hi I'm developing audio application using ALSA library. My target platform is ARM platform baseboard. I use GNU toolchain cross compiler as you can see from the following message: arm-none-linux-gnueabi-gcc -lasound -g -O2 -I./alsa-lib-1.0.17rc2/include -o pcm pcm.c /usr/bin/../lib/gcc/arm-none-linux-gnueabi/4.2.0/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -lasound collect2: ld returned 1 exit status make: *** [versatile] Error 1 I know that is because the linker cannot find the asound library.

[alsa-devel] Problems with alsa on ARM
by Alan Horstmann 12 Aug '08

12 Aug '08

Hi, I am trying to assist a collegue, we're working on ARM (AT91), and having probs with alsa stuff. Can anyone help interpret this strace from aplay -v -Dhw:0 ourfile.wav? I am comparing it to the same operation on a desktop PC. After all sorts of pre-amble, it gets down to accessing snd devices: open("/dev/snd/controlC0", O_RDONLY) = 3 close(3) = 0 open("/dev/snd/controlC0", O_RDWR) = 3 ioctl(3, USBDEVFS_CONTROL, 0xbecd36ac) = 0 ioctl(3, 0x40045532, 0xbecd36b4) = 0 open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK) = 4 close(3) = 0 ioctl(4, AGPIOC_ACQUIRE or APM_IOC_STANDBY, 0xbecd34f8) = 0 fcntl(4, F_GETFL) = 0x802 (flags O_RDWR|O_NONBLOCK) ioctl(4, AGPIOC_INFO, 0xbecd36a4) = 0 ioctl(4, AGPIOC_RELEASE or APM_IOC_SUSPEND, 0xbecd369c) = 0 mmap2(NULL, 4096, PROT_READ, MAP_SHARED, 4, 0x80000) = -1 ENXIO (No such device or address) ioctl(4, 0xc0844123, 0xbecd3618) = 0 fcntl(4, F_GETFL) = 0x802 (flags O_RDWR|O_NONBLOCK) fcntl(4, F_SETFL, O_RDWR) = 0 ioctl(4, AGPIOC_ACQUIRE or APM_IOC_STANDBY, 0xbecd398c) = 0 The first failure is from mmap2(..). Exactly the same line (and values) is successful on PC, but I don't know what it is doing or why it might fail. There are no other negative returns at all, but after opening the wav file, the playback info is written out, and set_params begins: ioctl(4, 0xc25c4110, 0xbecd3628) = 0 ioctl(4, 0xc25c4110, 0xbecd3628) = 0 ioctl(4, 0xc25c4110, 0xbecd3628) = 0 ioctl(4, 0xc25c4110, 0xbecd3628) = 0 ioctl(4, 0xc25c4111, 0xbecd3628) = 0 ioctl(4, 0xc0844123, 0x1c210) = 0 ioctl(4, 0xc0684113, 0xbecd3528) = 0 ioctl(4, 0x4140, 0) = 0 ioctl(4, 0xc0844123, 0x1c210) = 0 write(2, "aplay", 5aplay) = 5 write(2, ": ", 2: ) = 2 write(2, "set_params", 10set_params) = 10 write(2, ":", 1:) = 1 write(2, "1012", 41012) = 4 write(2, ": ", 2: ) = 2 write(2, "unable to install sw params:", 28unable to install sw params:) = 28 All seems to go OK with hw_params, but sw_params must return error (not seen) as the error check fails. The values printed out show xfer_align = 3201120484 which looks suspicious to me. Any clues on either of these would be greatly appreciated. Alan

[alsa-devel] Questions about /dev/snd and /proc/asound (new ASoC driver)
by Simon Tremblay 12 Aug '08

12 Aug '08

Hi, I have some issues with /dev/snd. First I should explain what I try to do. I am developing a driver for TLV320AIC23B codec and want to use it on a AT91RM9200-based board. I read documentation in sound/soc and created a codec driver (tlv320aic23b) and a machine driver (for my board). I think it's all I have to do since AT91 is supported and tlv320aic23b works with i2c and I2S. When I load my module I obtain that output: # modprobe snd-soc-armus-tlv320aic23b ASoC version 0.13.1 AIC23B Audio Codec 0.1 <6>asoc: aic23b <-> at91-ssc1 mapping ok <6>armus_tlv320aic23b: MCLK rate 12000000Hz armus_tlv320aic23b: Codec in Master Mode (I activated debug in soc-core and in my machine driver (based mainly on eti_b1_wm8731 machine driver)). I think there is no error here for now... But there is no /dev/snd created. I don't know for now why... Maybe someone has an idea? I think all I have in /proc/asound is correct too: In /proc/asound I have this listing: lrwxrwxrwx 1 root root 5 Jan 1 00:02 ARMUSTLV320AIC2 -> card0 dr-xr-xr-x 4 root root 0 Jan 1 00:02 card0 -r--r--r-- 1 root root 0 Jan 1 00:02 cards -r--r--r-- 1 root root 0 Jan 1 00:02 devices -r--r--r-- 1 root root 0 Jan 1 00:02 modules -r--r--r-- 1 root root 0 Jan 1 00:02 pcm -r--r--r-- 1 root root 0 Jan 1 00:02 timers -r--r--r-- 1 root root 0 Jan 1 00:02 version cat cards: 0 [ARMUSTLV320AIC2]: aic23b - ARMUS_TLV320AIC23B ARMUS_TLV320AIC23B (aic23b) cat devices: 0: [ 0] : control 16: [ 0- 0]: digital audio playback 24: [ 0- 0]: digital audio capture 33: : timer cat modules: 0 snd_soc_tlv320aic23b cat pcm: 00-00: TLV320AIC23B PCM aic23b-PCM-0 : : playback 1 : capture 1 cat timers: G0: system timer : 7812.500us (10000000 ticks) P0-0-0: PCM playback 0-0-0 : SLAVE P0-0-1: PCM capture 0-0-1 : SLAVE cat version (of alsa): Advanced Linux Sound Architecture Driver Version 1.0.15 (Tue Nov 20 19:16:42 2007 UTC).

[alsa-devel] Ideal fragment size and number range
by Rahul Iyer 12 Aug '08

12 Aug '08

Hi All For a reasonably responsive application, what would be the ideal fragment size and maximum fragment number range when set using SNDCTL_DSP_SETFRAGMENT (0xMMMMSSSS)? I understand the answer would correspond to the audio buffer size, but I am not certain about the formula involved here. Also for an hda-intel sound card what's the size of ring buffer (for both recording and playback)? Thanks ../rahul
