Playback stops working after a while.
I've noticed since MuseScore 3 released that playback consistently stops working only if I leave MuseScore idle for a while. When I go back to MuseScore and try to play something, nothing happens and no sound plays. The user can easily fix this by closing and restarting MuseScore. I just thought I'd point this out since this never happened with MuseScore 2.
