Command to unmute and maximize volume?

rated 0 times [ 8] [ 0] / answers: 1 / hits: 64293 / 2 Years ago, sun, october 9, 2022, 3:52:28

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?

Try the following commands in a terminal

amixer -c 0 set Master playback 0% mute

amixer -c 0 set Master playback 100% unmute

This should ensure all outputs are controlled. It's likely with your posted commands the reason the volume is not 100% is that the amixer does not release all outputs eg headphones or any other sound outputs at the same time.
