I have Xubuntu 16.04 on my Chromebook using Crouton. I am trying to enable my multimedia keys to work. I was able to get the volume up and down keys working respectively with:

'pactl set-sink-volume @DEFAULT_SINK@ -5%'

'pactl set-sink-volume @DEFAULT_SINK@ +5%'

What is the command to mute volume?

    I think it is set-sink-mute 0 1 to mute and set-sink-mute 0 0 to un mute, from command line. – hatterman Aug 5 '18 at 1:33


pactl set-sink-mute @DEFAULT_SINK@ 1


pactl set-sink-mute @DEFAULT_SINK@ 0

  • I actually got it with this. As this will bind a single key to mute/unmute which is what I needed.: pactl set-sink-mute @DEFAULT_SINK@ toggle – undyinglight May 8 '19 at 15:21
