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.
