That looks like it would work on my computer, but alsa works funny on my wife's computer. It has a channel called "wave" which is apparently different from "pcm". Anywho, the master volume doesn't do anything to her PC (very weird), so I adjust her volume by adjusting the wave channel, surround channel, and Aux2 Channel.
Unfortunately, aumix doesn't seem to have any commands to adjust those three channels.
Does anyone have an alternative method to using aumix or a method of configuring alsa so that the master volume truely affects all the other volumes. Is there a way I can rename the channels so that wave is pcm?
