Amixer

Change volume

• Set volume from terminal

For interactive usage you can use alsamixer. For scripting (e.g. binding to key combinations) take a look at amixer. alsamixer is included by default in most systems. To set the master volume use:

# Gets a list of simple mixer controls
$ amixer scontrols

Then set it to the desired volume, as an example

$ amixer sset 'Master' 50%
