Sound under 2.1.125

[Sangohn Christian]

Hello people!

I have Kernels 2.0.35smp and 2.1.125 with sound modules for the SB-AWE32.
With 2.0.35 there is no problem.
But I can't hear anything wtih 2.1.125. Kmix puts out:
"There is no mixer support for your system" although "ls -l /dev/mixer" 
is there:
crw-rw-r--   1 root     audio     14,   0 Jul 21 02:45 /dev/mixer

I've read the documentation in the Kernel sources.

So how can I fix that?

Thanks.
