Today I get no audio from MuseScore. All of the notices (dings etc.) are working; I can play mp3s on Windows Media Player; I can play project files on Audacity; but although MuseScore goes through the motions of playing a score (cursor marches along), there is no sound from the same speakers. The volume (from keyboard) is set at 58%; I uninstalled MuseScore and reinstalled it (3.6...), but it still won't make a sound.
Yesterday it was working; today it is silent. What did I screw up?
