I have a 2018 Mac Mini with three monitors attached. All three are DisplayPort and support audio. One of them has my audio system attached to it. The system and all other apps present no issues outputting audio in this setup, however Audacity doesn’t output any sound when this method is selected. If I choose my headset or the internal Mac Mini speakers I get audio without issue. I have tried all three instances of DisplayPort in the output drop down.

Any suggestions to try something else? I’ve never had issues getting Audacity to output on any system, Windows or Mac, simple audio or complex interfaces. This is a first.
Thanks!
