RedHat 8.0 and SB Audigy

Hi -

I'm just started using Linux, and I'm in the process of setting up my 
PC. Everything seems to be working fine except for my sound card.
RH detects that I've got a SB Audigy just fine, but when I try to play a 
sound  - even the test sound - it doesn't work.

In my System Log file, the following was scrolled repeatedly:
Mar 24 20:08:08 dyn-196-128 modprobe: modprobe: Can't locate module 
sound-slot-0
Mar 24 20:08:08 dyn-196-128 modprobe: modprobe: Can't locate module 
sound-service-0-3

Thanks for helping a Linux newbie! :)
