Sorry to butt in, but saw this post recently and have some possibly 
related problem with sound on amd64 8 beta2 but snd_ich driver.
the driver is ok it seems, but the sound produced is distorted; to the 
point i thought my speakers had died. i dual boot fedora 10 and they 
sound fine there, even directly hooking up the ipod eliminated the thought.

i don't post here cuz i am a noob and just trying to learn something, 
but noticed the distortion first time i installed beta1, (now updated to 
beta 2 yesterday), unless i need some settings i didn't need in 7.x.
