soundcard and driver detected, butFATAL error, and no sound

When booting KNOPPIX 4.0 from DVD, i get the following message:

soundcard = Vortex 2 driver = au8830
modprobe : FATAL : Error running install command for sound_slot_0

So my soundcard doesn't work. Is there something that i can do?
Maybe an BIOS setting?
