It is like the output is muted or >>something needs to be turned up. Also in a program like "kmix" the >>master volume is missing... strange. 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. >>Today i have tried with a cvs snapshot from 8th may.

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. >>I can supply more information on request like contents of /proc/isapnp >>and stuff like that.
