Playback is broken
The problem started when I put on my headphones. Musescore kept doing playback from my computer speakers, even though my computer settings had all my audio going through my headphones. I went to preferences to change it to my headphones, I selected my headphones in the preferences I/O menu and hit apply. The only thing that changed is now there is no sound. I've gone back to the I/O menu and now there is no option to select a playback device in preferences anymore.
The 'Restart Audio and MIDI Devices' button does nothing, the 'Reset All Preferences to Default' button does nothing, and now (after resetting the entire program to factory settings) the 'Mixer' and 'Synthesizer' options are completely grayed out in the view menu.
What is up with this program? Why do the playback and audio setting refuse to even populate now? How do I fix this?
