I don't know if this is the right forum, but I was just wondering why my PCM volume in Gnome still let's through sound when it's way at the bottom? It even shows the little red 'X' there on the taskbar-icon. (I use PCM to set my volume and keep master at the way top, since I'm guessing PCM is closer to the source of the sound - at least, if I have PCM at the way top and use master, I can't have the sound as loud without distortion from my little laptop.) Of course, opening the volume control program and clicking the speaker-icon to turn off sound works, just wanted to be able to mute by turning the volume way down...

well as PCM and master volume both are responsible

PCM is same as the wave output in windows
so i think u still will have some sound even if PCM is down
