I need to mute/unmute from the command line. I found out that I can do it with:
amixer sset Master mute amixer sset Master unmute
the problem is that the command for unmute is not working (as described also in this bug report: https://bugs.launchpad.net/ubuntu/+source/alsa-utils/+bug/878986)
My question is: is there another way to obtain the same result, taken that amixer is not working?
Furthermore, if I set manually the volume to minimum and then call
amixer sset Master 100%
the volume increases but doesn't switch to maximum, even if the stdout tells:
Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] [on] Front Right: Playback 31 [100%] [0.00dB] [on]
Can anybody help me with this?
