Musescore 4 not opening

• Jan 4, 2023 - 21:21

Musescore 4 does not open If the audio on your pc is set to any of the SteelSeries Sonar. Switching It to anything else fixes the problem and Musescore 4 will begin to work after.


I have never googled a technical problem and had it answered perfectly on the first link when what the issue turned out to be was this specific. Bravo & ty!

I have never thought that some random page with 2 replies would save my day. Thank you so much! I would have never solved this issue if it wasn't for you. Words cannot express how grateful I am for this.

I googled "Musescore 4 not working" and this was the first thing, and I just happen to be using Steelseries Sonar. That is the craziest thing.

Thank you so much for pointing this out, for the past 3 days I've been figuring out why it keeps crashing for me. Yeah, you have to choose one of the (Speakers) devices instead of (Steelseries Sonar - etc...). Gonna keep this saved for future reference.

Musescore 4, Windows 11, has worked fine for me for many months, but tonight something went wrong when I closed a score, and now it will not open. When I try to start it from its icon or from a score, all I get is a tiny stub on the taskbar. I have restarted Windows and reinstalled Musescore 4 (latest version) but it still will not open. I don't have SteelSeries Sonar (I have never heard of it), nor have I changed my audio setup in any way.

Thanks. I uninstalled, then manually removed all remaining MS directories , then reinstalled, and I seem to be back in business. I didn't have any of my scores in MS directories, and I easily reintroduced my modest customizations. Perhaps such scrubbing should be an option in Uninstall.
I am also interested in when something like the mobile Score View will be available within MS for Windows devices, but I guess I should look for this elsewhere.
