UID property is empty

{
  "name": "MacBook Pro Microphone",
  "type": "input",
  "id": "82",
  "uid": ""
}
{
  "name": "ZoomAudioDevice",
  "type": "input",
  "id": "49",
  "uid": ""
}
{
  "name": "MacBook Pro Speakers",
  "type": "output",
  "id": "75",
  "uid": ""
}
{
  "name": "ZoomAudioDevice",
  "type": "output",
  "id": "49",
  "uid": ""
}

It would be great to be able to use the UID: I have two external monitors and want to occasionally route audio through one, but their int ids occasionally change. But for some reason those periodically change, so the UID would be preferable.

[thewellington]

Agreed. I could make use of the UUIDs too

Is this a universal problem? Or is it specific to some version of the OS?

I'm OS X 11.7.4 and it still works for me:

SwitchAudioSource -a -f json

{"name": "Notabrick Vibe", "type": "input", "id": "57", "uid": "50-c0-f0-e5-e0-2d:input"}

I'm on 13.0, and I believe it was an issue when I was on 12.x as well: is it possible that something changed in one of the latest versions?

[deweller]

I've published version 1.2.0. This replaces some of the deprecated system calls. Perhaps this will resolve the issue on the more recent operating systems.

[Sigafoos]

I just upgraded to 1.2.0 via homebrew and still no uids

[deweller]

Got it. I think @tannerellen has a fix for us in #52.

[deweller]

Version 1.2.1 includes #52 and is merged into homebrew
