MuseScore Problem | MuseScore

Are yoiu saying the problem has nothing to do with the citures, and is simply that MuseScore won’t produce sound when entering notes by any means, and also won’t produce sound when playing an existing score?

If so, see musescore.org/en/node/96811

If not, please explain your problem as clearly and precisely as possible. Say what you are doing step by step, and at which step something goes wrong – what you are doing, what you expect to see/hear happen, what happens instead.
