Musescore 3 and 4 not working
Whenever I try to use Musescore 4, the playback is messed up in some way. Whenever I open it with my headphones plugged in, the playback is at half speed and an octave too low. If I unplug my headphones and try to play it again using my speakers, it's at about 4x speed and an octave and a half too high. If I open Musescore without my headphones plugged in, the sound is at 2x speed and an octave too high, and if I then plug in my headphones in, it's at 1/4 speed and an octave and a half too low.
I've tried unplugging my speakers and headphones, restarting my computer, uninstalling and reinstalling Musescore, using different versions of Musescore 4, and changing every sound setting I could think of. (This probably doesn't matter, but if I switch to mono audio on either device, I can click the play button, but nothing gets played.)
I decided to just try to use Musescore 3 instead, but all of the buttons on the playback bar are always grayed out and don't work. (This is the reason I switched to Musescore 4 in the first place) I've tried all of the same things I did with Musescore 4 with Musescore 3 as well.
I only have 2 other things I can think of at this point.
I could factory reset my computer, but I feel like I'll screw up something in the process, or I could just go back to Musescore 2, which I don't have installed on my computer and don't even know how to find.
