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
Please provide the output of 'amixer scontrols' as @mikewhatever requested. To the best of my knowledge (and testing over numerous platforms) there is no master mono channel in Alsa mixer –  Elder Geek May 17 '14 at 22:52
