Audio troubles & Far Cry

[Firebird]

I am having trouble with my audio in Far Cry. I am running an Athlon xp 2600, an ASROCK K7S8XE mobo with onboard CMEDIA audio, and a Geforce FX5700LE. The audio is garbled only on far cry, and i even tried the demo and got the same results. I can't seem to be able to reproduce the problem outside of the game. Is it Far Cry? Anyone else else have this problem??
