I have solved the problem about missing audio by just unmuting "Master 
Digital" :-)  I didn't know there was a muting function in alsamixer 
until i saw it mentioned in another mail on this list and i didn't need 
to unmute any channels on my other soundcard.
There is still no master volume in kmix (and probably other oss sound 
mixers) however.

I have found out that the cs4236_lib.c file did not change between rc1 
and the cvs snapshot. It only happens sometimes that the module won't 
load because ver1 != ver2. When I loaded the module the first time today 
they were both 0, but after unloading it and loading it again ver1 was 0 
and ver2 was 191.
I don't know exactly when this problem appears. I will watch it a bit 
the next days and see if for instance the problems only occurs when 
reloading the module.
