alsa upgrade: sound only from one app [Solved]

cinan · 2009-09-08 18:30:56

Hello,
after upgrade to alsa 1.0.21 only one application can play sound. E.g. if MPD (using ALSA output) plays then any ather application (mplayer for example) cannot. Here's mplayer output:

[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource busy
[AO_ALSA] alsa-lib: conf.c:4626:(snd_config_expand) Expand error (walk): File exists
[AO_ALSA] alsa-lib: pcm_hw.c:1325:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: Device or resource busy
[AO_ALSA] Playback open error: Device or resource busy
[JACK] cannot open server
[AO SDL] Samplerate: 44100Hz Channels: Stereo Format s16le
[AO_ALSA] alsa-lib: conf.c:4626:(snd_config_expand) Expand error (walk): File exists
[AO_ALSA] alsa-lib: pcm_hw.c:1325:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: Device or resource busy

I've downloaded and compiled older alsa-{lib,utils} 1.0.20 from ABS. Now's everything fine.

I've got the same error after upgrading.
I figured out that the programs doesn't use PCM as device but use the play device (Front for me) directly.

Vi0L0 · 2009-09-08 22:23:01

Same for me .
I belive it's better not ot delete old packages from /var/cache/pacman/pkg/ as quick as possible.
Using
pacman -U /var/cache/pacman/pkg/some.application.pkg.tar.gz
is much faster than using abs, or... waiting for newer version which will work (i've heard about that cases in yesterday news)

Edit: Im using kernel 2.6.30.5-1, Realtek ALC888 (integra)

I have this too,
mostly where it said CONF.C: Expand error: File exists. & Resource busy.

Besides this, I don't know why my flash just stopped working with other sound programs.
Even I downgraded to alsa-lib 1.0.20, flash still took control of the device everytime I play one.
Just before upgrade, I could do all that...

Are u shure u r not using some 32 bit flashplugin on your 64bit Arch? Like nspluginwrapper-flash for example. If so - downgrade your lib32-alsa-lib too

b4283 · 2009-09-09 11:48:41

Woot! I can't believe I missed lib32-alsa !
It worked. Thx Vi0L0.

I'm just out of luck, I recently cleared my package cache because I ran out of disk space. I seem to remember there was a script which would automatically list old packages that are archived and install them to downgrade. I can't seem to find it.

shaurz · 2009-09-09 18:13:31

Aha, found it in /root

mrunion · 2009-09-09 18:16:06

FWIW, on my laptop (32-bit) I upgraded to alsa 1.0.21, but I can play flash and vlc stuff at the same time. I'll try on my 64-bit macine at home as soon as I can.

PierreR · 2009-09-09 19:03:56

I have tried with no luck to mess with the config files (modprobe.conf).

So I 've ended up downgrading alsa-lib and alsa-utils to get the sound back (which is quite easy thanks to pacman cache)

Nagian · 2009-09-09 19:10:52

I also had to downgrade these packages...

I also have a laptop with 32 bit, so it's not because of the architecture... I am using snd-hda-intel, maybe that's the reason... What do the others have for sound card modules?

me too, 32bit & snd-hda-intel.
Where exactly is the problem? In alsa or kernel or snd-hda-intel module?

theapodan · 2009-09-10 00:14:06

I don't know if this will do any good, but you might try renaming /etc/asound.state, restarting alsa, and run alsactl store to let alsa recreate it.

mrunion · 2009-09-10 00:27:29

OK, got home, upgraded the 64-bit machine to 1.0.21 and rebooted. I got sound from both youtube.com and vlc at the same time. Is there any info you may want from me to help with this problem?

Do you use snd-hda-intel? I suppose there is the problem...

draugdel · 2009-09-10 12:00:15

Fixed for me with alsa-lib 1.0.21.a-1.

cinan · 2009-09-10 12:15:36

second that, fixed with alsa-lib 1.0.21.a

Andrwe · 2009-09-10 12:17:50

For me too.

ChemBro · 2009-09-10 16:45:24

Me too. I'm glad it was only one day (or two?). Nice super fast support.

monofluor · 2009-09-11 13:06:56

For mi its not working again...
I've updated alsa-lib + a kernel update.... every things go fine until reboot, the i have the same problem.

cinan · 2009-09-12 13:32:00

It seems to be kernel26-related issue. I didn't upgrade to the newest .30.6, I'm waiting for .31. You could try downgrade kernel or alsa.

finally resolved, seems to be the sound was blocked for one aplication. I closed all and restart and voila. Thanks

simkin · 2009-09-15 13:19:15

In my case, I solved it removing the pulseaudio server and related stuff.
After restarting, more than one app could use the sound device again.

_will · 2009-09-18 20:23:56

I had a similar issue with MPD blocking sound on ac97. Commenting out optional decelerations under audio_output in /etc/mpd.conf fixed it.

/etc/mpd.conf wrote:

audio_output {
type "alsa"
name "My ALSA Device"
#device "hw:0,0" # optional
#format "44100:16:2" # optional
#mixer_device "default" # optional
mixer_control "PCM" # optional
#mixer_index "0" # optional
}
