PCM Volume control not working
 
Hey all,
I'm trying to adjust the volume in alsamixer with the PCM bar, but it doesn't seem to be doing anything... My sound card works and I can change volume of the Front, center, side speakers in alsamixer with out any problem.
Any Ideas? I'm not really even sure what pcm is except that in other computers it will change the master volume.

Hi Dankles, What sound card is this?
Good luck. ;-)

Do you have a surround51 or surround40 channel available?
Good luck. ;-)
