Bug 117048

Which driver?  Show /proc/asound/cards.
Try to clean up unused semaphores via ipcrm?

Also strace would be helpful.

Hmm, the relevant part hasn't been changed since beta4.  Possibly the compiler
was changed...

Can you try the package on bari-tiwai-12?

f55:~ # aplay /usr/share/sounds/alsa/test.wav 
ALSA lib pcm_direct.c:806:(snd_pcm_direct_initialize_slave) requested or
auto-format is not available
ALSA lib pcm_dmix.c:830:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:540: audio open error: Invalid argument

Try to copy the following to /usr/share/alsa/cards.

VIA686 config

doesnt help.

How about the one on bari-tiwai-13?  (Don't use the file in commment #7.)

I can bring it in your office if you want, its a very small box.
sound works ok with 2.6.11 debian kernel, only with the plug on the backside,
not on the frontpanel.

It's no driver bug just a problem regarding dmix plugin with ppc.
Writing the following to ~/.asoundrc would fix, but you lose the soft mixing, too:

   pcm.!default "plughw"

And, no, please don't bring it to me.  I have no time at all.

yes, that works.  

Also let me know whether bari-tiwai-13 works.  If not, please attach the errors
again.

just using the new alsa.rpm fixes it.

The package was submitted to STABLE.
