Playback has no sound after computer wakes from sleep

• Feb 17, 2025 - 15:09

This has been a longtime problem with Musescore 3 and up to now with the latest Musescore 4 on my setup. Not sure if it has anything to do with it but I am using iMac 2017's headphone output driving external amp/speakers.

When Mac wakes from sleep and I hit play in Musescore, there is no sound. Closing and reopening the file does not help. I have to quit Musescore and open it again to get sound back. Youtube, Music and every other app with sound plays fine so the problem is with Musescore only. Any help appreciated.

This is almost definitely something that the MuseScore developers could fix, so it is good to confirm that it affects many people so that they know that it is a real issue.

It is likely possible for the application to check if the audio subsystem is working correctly using the system API and to reset it from within the application if it is not working, or at the very least to provide an option from within the app to manually reset the audio system without closing and re-opening the app.

There is an issue on GitHub that seems to represent this problem: https://github.com/musescore/MuseScore/issues/17163
