HOWTO.md
  1. Create a /usr/local/bin/audiointerfaceswitch.sh file with the content above. Change "FiiO USB DAC-E10" with the name of your interface. Run /usr/local/bin/SwitchAudioSource -a to get a list of the available interfaces on your system.
  2. With Automator.app, create an app
  3. Run the app to switch interfaces. Use a launcher or BetterTouchTool or a similar tool to map the app to a keyboard shortcut.
