is it really alsa-lib and not the drivers?  IE, if youu downgrade alsa-lib, does your sound work?

[Comment 2 Alexander Jenisch 2004-05-05 05:10:43 UTC]

uh... sorry. i'll change the topic. it must be the driver of course. i never had problems before with alsa-lib 1.04.

[Comment 3 Jeremy Huddleston (RETIRED) 2004-05-15 00:43:03 UTC]

can you please try using alsa-driver-1.0.4.  If that doesn't work, then you will need to file a bug report upstream at alsa-project.org.  Please report the bug number here when you do.

upstream problem...
