I'm using Lubuntu 13.04 and am looking for the command to raise and lower my volume in increments so I can add that command to my lubuntu-rc.xml file thus binding it to my XF86AudioRaiseVolume (i.e. Fn+Uparrow) key. Right now, according to the lubuntu-rc.xml file, the Fn+Uparrow combination executes amixer -q set Master 3%+ unmute
, but when I type this command in the terminal I get the error message amixer: Unable to find simple control 'Master',0
.
I've looked at similar questions, but they've availed me nothing. I really don't understand ALSA (nor PulseAudio).

, command will only decrease the volume to 8 (not 0), 2. the volume increase and decrease commands do not unmute (even though each ends with the textunmute
, and 3. theamixer -c 1 -q sset Master toggle
command, which is supposed to toggle mute, only mutes (it does not unmute).
