I use "master mono" for my audio. I like using the volume up and volume down buttons on my keyboard but they only change "master" not "master mono". Anyway to change this?

Is "master mono" a channel in the Alsa Mixer? If it is, can you add the output of amixer scontrols to the question. –  mikewhatever Dec 25 '12 at 17:22

The volume keys are handled not by alsamixer but by your desktop environment. Which one? –  CL. Dec 25 '12 at 21:53
