I'm not too sure, but i _can_ tell you that lastly i had two weird errors
about something adb, when snd-au8810 didn't play any sound anymore, i was
able to kill all apps who use sound and modprobe -r snd-au8810, and modprobe
again, and without reboot i was able to get sound working again.

I must say that i haven't been on this PC much and haven't had much time to
test these things, allthough i'm planning too, (but i think i'll update CVS
first with these 2 patches who got lost accidentally before i test this. I
hope i'll get some time this week(end).

thanks for all the help and info concerning snd-au8810 (in 64bit)
