[alsa-devel] error in snd_pcm_drain()
by Eliot Blennerhassett 05 Jul '07

Maybe an error in snd_pcm_drain - not sure what effect it might have... snd_pcm_group_for_each_entry(s, substream) { runtime = s->runtime; ... } up_read(&snd_pcm_link_rwsem); snd_pcm_stream_lock_irq(substream); /* pcm_native.c around line 1491: */ /* error? runtime has been changed by group_for_each should use substream->runtime instead? */ /* resume pause */ if (runtime->status->state == SNDRV_PCM_STATE_PAUSED) snd_pcm_pause(substream, 0); -- Eliot

[alsa-devel] Very low headphones volume on HDA + Realtek ALC268
by Maurizio Monge 04 Jul '07

04 Jul '07

Hi, i've got an hda/alc268 card (pci id: [8086:284b], subsytem id: [1025:011f]) on my laptop, and the sound is ok for the loudspeakers but it is very very low for the headphones (the volume is at the top in the mixer, if i reduce the volume in the mixer the sound gets even lower). Under windows vista the headphones work well (ok, worked, before that i removed windows from my computer). I am using alsa hg, the most recent version at the moment i'm writing this e-mail. I there is any experiment that i can do or if i can help in any way (i know C very well) to fix this bug just let me know, and i'll be happy to contribute. More information about the hardware follows.

[alsa-devel] Easiest way to test playback on an ASOC driver?
by Timur Tabi 04 Jul '07

04 Jul '07

I'm in the early stages of testing an ASOC driver, i.e. I'm trying to get playback to work. What is the easiest way to test playback? Is there a particular tool I should be using that does the most basic and direct playback of audio data through ALSA? -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] left/right bleed or crossover
by Howdy Pierce 04 Jul '07

04 Jul '07

I'm encountering the following problem on Fedora Core 6 running on a Dell Optiplex 745. This is a pretty vanilla computer with an ICH8 chipset and integrated AD1983 sound capabilities. I have wired up a funky line-input cable so that I have completely separate audio sources playing on the left and right inputs. When I either play these through to the speaker output directly (using alsamixer), or record the audio using arecord, the result is that there is a slight bit of bleeding or crossover, so I can faintly hear the left input on the right channel, and vice versa. If I record a wav file and then play it on another computer, the left/right bleeding follows the wav file, so it seems that the problem is in the capture process somehow. When I install Windows XP onto the same machine, the problem disappears, so I can rule out hardware errors. The application I'm working on relies on being able to reliably capture the right and left channels of audio independently. Since the problem can be seen using the standard arecord/aplay tools, though, I don't think it's my code. I've tried all the possible combinations inside alsamixer, and I don't think there's anything I've messed up there. I've put the relevant system details below. Thanks for any help you can provide. --Howdy ============================= Howdy Pierce Managing Partner Cardinal Peak, LLC work: (303) 665-3962 x101 cell: (303) 589-1645 email:

[alsa-devel] Errors in application building
by Paul Kavan 03 Jul '07

03 Jul '07

Hello all: I am working on my first bit of application code for ALSA and am not sure how to properly compile it against the libs. I have to cross compile the application on my host machine i686 PC for use on a ARM development board. I copied the alsa include directory into my staging include directory (this is where the cross-compiler works from), which allowed the program to find alsa/asoundlib.h However, I am still getting some errors that indicate to me it cannot find everything it needs. I am getting the following errors: grhuser@pcL7:$ arm-linux-gcc -Wall -o grh_audio grh_audio.c grh_audio.c: In function 'grh_capture': grh_audio.c:113: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness grh_audio.c: In function 'grh_playback': grh_audio.c:208: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness /tmp/ccMn48zN.o: In function `grh_capture': grh_audio.c:(.text+0x16c): undefined reference to `snd_pcm_open' grh_audio.c:(.text+0x198): undefined reference to `snd_strerror' grh_audio.c:(.text+0x1c0): undefined reference to `snd_pcm_hw_params_malloc' grh_audio.c:(.text+0x1e4): undefined reference to `snd_strerror' grh_audio.c:(.text+0x214): undefined reference to `snd_pcm_hw_params_any' grh_audio.c:(.text+0x238): undefined reference to `snd_strerror' grh_audio.c:(.text+0x26c): undefined reference to `snd_pcm_hw_params_set_access' grh_audio.c:(.text+0x290): undefined reference to `snd_strerror' grh_audio.c:(.text+0x2c4): undefined reference to `snd_pcm_hw_params_set_format' grh_audio.c:(.text+0x2e8): undefined reference to `snd_strerror' grh_audio.c:(.text+0x324): undefined reference to `snd_pcm_hw_params_set_rate_near' grh_audio.c:(.text+0x348): undefined reference to `snd_strerror' grh_audio.c:(.text+0x380): undefined reference to `snd_pcm_hw_params_set_channels' grh_audio.c:(.text+0x3a4): undefined reference to `snd_strerror' grh_audio.c:(.text+0x3d4): undefined reference to `snd_pcm_hw_params' grh_audio.c:(.text+0x3f8): undefined reference to `snd_strerror' grh_audio.c:(.text+0x420): undefined reference to `snd_pcm_hw_params_free' grh_audio.c:(.text+0x42c): undefined reference to `snd_pcm_prepare' grh_audio.c:(.text+0x450): undefined reference to `snd_strerror' grh_audio.c:(.text+0x494): undefined reference to `snd_pcm_readi' grh_audio.c:(.text+0x4c0): undefined reference to `snd_strerror' grh_audio.c:(.text+0x500): undefined reference to `snd_pcm_close' /tmp/ccMn48zN.o: In function `grh_playback': grh_audio.c:(.text+0x5b8): undefined reference to `snd_pcm_open' grh_audio.c:(.text+0x5e4): undefined reference to `snd_strerror' grh_audio.c:(.text+0x60c): undefined reference to `snd_pcm_hw_params_malloc' grh_audio.c:(.text+0x630): undefined reference to `snd_strerror' grh_audio.c:(.text+0x660): undefined reference to `snd_pcm_hw_params_any' grh_audio.c:(.text+0x684): undefined reference to `snd_strerror' grh_audio.c:(.text+0x6b8): undefined reference to `snd_pcm_hw_params_set_access' grh_audio.c:(.text+0x6dc): undefined reference to `snd_strerror' grh_audio.c:(.text+0x710): undefined reference to `snd_pcm_hw_params_set_format' grh_audio.c:(.text+0x734): undefined reference to `snd_strerror' grh_audio.c:(.text+0x770): undefined reference to `snd_pcm_hw_params_set_rate_near' grh_audio.c:(.text+0x794): undefined reference to `snd_strerror' grh_audio.c:(.text+0x7cc): undefined reference to `snd_pcm_hw_params_set_channels' grh_audio.c:(.text+0x7f0): undefined reference to `snd_strerror' grh_audio.c:(.text+0x820): undefined reference to `snd_pcm_hw_params' grh_audio.c:(.text+0x844): undefined reference to `snd_strerror' grh_audio.c:(.text+0x86c): undefined reference to `snd_pcm_hw_params_free' grh_audio.c:(.text+0x878): undefined reference to `snd_pcm_prepare' grh_audio.c:(.text+0x89c): undefined reference to `snd_strerror' grh_audio.c:(.text+0x8e0): undefined reference to `snd_pcm_writei' grh_audio.c:(.text+0x90c): undefined reference to `snd_strerror' grh_audio.c:(.text+0x94c): undefined reference to `snd_pcm_close' collect2: ld returned 1 exit status My application code is attached.

Compiling alsa-lib-1.0.14rc4 with the above options: ./configure --disable-aload --disable-alisp --disable-instr --disable-seq --disable-hwdep --disable-rawmidi --with-debug=no --with-pcm-plugins=hw --with-ctl-plugins=hw After the build of asound and a linking against a simple program: #include <stdio.h> #include <stdlib.h> #include <alsa/asoundlib.h> main (int argc, char *argv[]) { int i; int err; short buf[128]; snd_pcm_t *playback_handle; snd_pcm_hw_params_t *hw_params; if ((err = snd_pcm_open (&playback_handle, argv[1], SND_PCM_STREAM_PLAYBACK, 0)) < 0) { fprintf (stderr, "cannot open audio device %s (%s)\n", argv[1], snd_strerror (err)); exit (1); } snd_pcm_close (playback_handle); exit (0); } gcc -o teste teste.c -I./include src/.libs/libasound.so.2.0.0 -ldl src/.libs/libasound.so.2.0.0: undefined reference to `snd_hwdep_info_get_name' src/.libs/libasound.so.2.0.0: undefined reference to `snd_rawmidi_info_get_name' src/.libs/libasound.so.2.0.0: undefined reference to `snd_rawmidi_info_sizeof' src/.libs/libasound.so.2.0.0: undefined reference to `snd_rawmidi_info_set_device' src/.libs/libasound.so.2.0.0: undefined reference to `snd_hwdep_info_set_device' src/.libs/libasound.so.2.0.0: undefined reference to `snd_hwdep_info_sizeof' src/.libs/libasound.so.2.0.0: undefined reference to `snd_rawmidi_info_set_stream' collect2: ld returned 1 exit status After some verification discoverd that the problem is on src/control/namehint.c that references this functions but the configure removed rawmidi and hwdep. How can we resolve this problem? Fausto Carvalho Marques Silva
