no sound on 82801DB AC'97 Audio Controller

[Dovydas]

I have just installed FC3 on hp nx9030. Everything is fine, except I
have no sound.
Sound card is detected properly.

Sound modules are installed.

Everything seems ok, but I hear no sound. artsd uses 95% of CPU and crashes
couple minutes after boot.
What could be wrong?
