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 HDMI audio and headphones.

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.
