Playback coming through speakers even though headphones are plugged in
I've got a problem that's quite an annoyance. I'm using MuseScore 3.5 Portable, which is working fine, except when I plug headphones in, all the applications play their sound through the headphones.
All of them, that is, EXCEPT MuseScore! It plays through the speakers.
How do I fix this? I'm using a school computer, so I don't have admin rights. And do NOT tell me I need them to fix this problem.
