PulseAudio Volume Controller with Sink Selection

volume.sh

#!/bin/sh

# This script determines the currently active pulse audio sink.
# That makes it possible to use the function keys,
# regardless if you are listening via bluetooth, cable, or local speakers.

# Uncomment and add the following to your `.config/i3/config` to bind volume keys (X window)

  ## bind function keys (fn)
  #bindsym XF86AudioRaiseVolume exec --no-startup-id /opt/custom-scripts/volume up
  #bindsym XF86AudioLowerVolume exec --no-startup-id /opt/custom-scripts/volume down
  #bindsym XF86AudioMute exec --no-startup-id /opt/custom-scripts/volume toggle
