need sound driver ?

[arcticsheep]

As some of you know from my last post, I re-installed OS X and for some reason this time everything worked fine except my sound (?), which worked flawlessly last time (when my resolution didn't work :S)

I have no idea I never touched any driver other than graphics ones (ATI/ NV/ Ge)

Can anyone help me? I'm really clueless here.

Specs:
ASUS M2N-E SLi
X1650pro 512
athlon64 x2 2.5ghz (am2)

my sound quote

"ADI 1988 8-channel High Definition Audio CODEC
Support Jack-Sensing, Enumeration, Multi-streaming and Jack-Retasking
S/PDIF out on back I/O port"

thanks all
