I am trying to figure out which device is the built-in output device on my Mac? when I use exec -a -f json in the list I can see
{"name": "MacBook Pro Speakers", "type": "output", "id": "366", "uid": "BuiltInSpeakerDevice"}
But my concern is that is it safe to use the uid BuiltInSpeakerDevice? will it be the same on all Mac devices and OS versions?
