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

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

Customizations

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work

Keychron Keyboards on Linux use the hid_apple driver (even in Windows/Android mode), both in Bluetooth and Wired modes. By default, this driver uses the F-keys as multimedia shortcuts and you have to press Fn + the key to get the usual F1 through F12 keys.
