Audio device selection not possible

• Dec 7, 2021 - 14:17

I can't select any MIDI or Audio devices via the settings. Also no sound in the application; mixer, synthesizer are all greyed out as well. I'm on Big Sur 11.6 on a MacBook Pro 15" 2017.
Same problem as in this unresolved thread:
I tried reinstalling, restarting etc, no luck.

I tried setting the computer to built-in speakers, as well as using an external Interface (Universal Audio Apollo), but in Musescore, I can't select any device at all. Under "PortAudio" in settings, all the tabs are empty and I can't click them.

I don't use Komplete Kontrol, so that can't be the issue. I do have a lot of Audio Software on my Computer, but a) none of them were running while opening Musescore and b) that hasn't been a Problem for about 4 years of using Musescore alongside... The problem started to appear with the last or one of the last Musescore updates.

My version, if that's any help:

OS: macOS 10.16, Arch.: x86_64, MuseScore version (64-bit):, revision: 3224f34
