Here are some linux commands (pactl and amixer) to increase and decrease volume. You can also use these commands to set keyboard shortcut to increase and decrease volume.
pactl command is used to control a running PulseAudio sound server.
Increase volume by 10%
pactl -- set-sink-volume 0 +10%
Decrease volume by 10%
pactl -- set-sink-volume 0 -10%
Set volume to 80%
pactl -- set-sink-volume 0 80%
Set volume to 200%

Keyboard shortcut to increase/decrease volume
I am using Xubuntu. For Ubuntu users, you can search for keyboard in dash.
I have set “Super & +” key to increase volume and “Super & -” key to decrease volume. The following steps will create shortcut keys to increase and decrease volume by 2%.
– Go to Settings Manager
– Go to Hardware -> Keyboard
– Go to ‘Application Shortcuts’ tab
– Click ‘Add’ button
– Write the command:amixer set Master 2%-
– Type Super and – (minus) key
– Again click ‘Add’ button
– Write the command:amixer set Master 2%+
– Type Super and + (plus) key
Hope it helps.
Thanks.
