master volume doesn't work, PCM does
Last modified: 2007-11-30 17:11:11 EST
Setting soundcard to mute in gnome or in terminal with alsamixer has no effect.
Also, if settings master volume to 0% it doesn't really mute sound, must also
drag PCM volume to 0% to mute wave.
In case this is not sound-card independent, mine is Intel 82801DB-ICH4.
What is the problem? You can't mute your soundcard by any mute switch and you
have to use volume sliders?
After more testing: The problem is that Master volume doesn't have any effect,
only PCM works. So Mute for Master (or volume slider) doesn't work, only the one
Yes, It's a common problem with the Master volume slider, it doesn't work for
many cards. Upstream already works on this issue.
