Weird sound behaviour

Some weird sound behavior just occured all of a sudden.

Typing in notes by mouse works perfectly - it produces a note and a sound.

Doing it by midi keyboard produces a note but no sound.

How can this happen. Haven‘t changed anything since yesterday.

Restarted Dorico (4.1), and PC - nothing changed.

Maybe someone can help. Thanks.

I just saw that there is already an open thread on this topic but no solution yet.

Hey I have the same problem, not yet a real solution, but did you try to save the project and re-open it? And do you also get weird other sounds when playing with the keyboard? Just out of curiousity :sweat_smile:

Please add any further information to this other thread:
