snd-cs46xx driver loading failure
 

Howdy,
I have recently upgraded to SUSE 9.0.
Since then my sound card has ceased to work correctly... or indeed at all.
I have attempted to configure the sound card with YAST2 but it always comes up with the same error:

The kernel module snd-cs46xx for sound support could not be loaded. This can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

Any help anyone could give me would be highly appreciated.
Jim.
