Audio Output Switcher

This script will cycle to the next available audio output device. It can be tied to a hotkey to easily be triggered. This is handy, for example, for swapping between speakers and headphones.

This script will work on systems running PulseAudio or Pipewire services.

Install

Download the audio-device-switch.sh script and place it in /usr/local/bin.
Make the script executable: sudo chmod 755 /usr/local/bin/audio-device-switch.sh.
Open the Keyboard Shortcuts settings page, add a new shortcut, tell it to execute audio-device-switch.sh, and set up your shortcut!
Install the notify-send library if you want to see a popup notification when the audio device switches: sudo apt install libnotify-bin.
