For binding to keyboard shortcuts:

#(Volume Up)
amixer set Master 5%+ 
#(Volume Down)
amixer set Master 5%-
# (Mute/Unmute)
amixer set Master toggle

 

# get volume: Right
amixer sget Master | grep 'Right:' | awk -F'[][]' '{ print $2 }'
85%
# get volume: Left
amixer sget Master | grep 'Left:' | awk -F'[][]' '{ print $2 }'
85%

#!/bin/bash

mute=audio-volume-muted
