[Pkg-alsa-devel] Bug#507734: [alsa-base] No sound after (re)boot with snd-via82xx

[Mikael Petersson]

Package: alsa-base Version: 1.0.17.dfsg-4 Severity: important

Hello, 

I have problems getting sound from my Via card using the snd-via82xx
module. The module doesn't seem to be automatically loaded during boot.

After running alsaconf everything works like a charm, but only as long
as I don't reboot. After reboot I have to run alsaconf again to have
working sound. 

This problem began a few weeks ago. Until then everything worked as it
should. Unfortunately, I don't know the real source of the problem. It
may be alsa-base, udev, the kernel (I use a Debian stock kernel) or
whatever. Please feel free to redirect this bug report to the correct
package if this is no alsa-base bug!

Regards,

Detailed bug info
=================

Error messages from speaker-test after reboot and before running
alsaconf ("Filen eller katalogen finns inte" is swedish for "The file
or directory does not exist"):
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: Filen eller katalogen finns inte

Some text emitted during alsaconf execution:

After running alsaconf, speaker-test generates pink noise, just as it
should.
