MuseScore gets stuck on splash screen if USB audio interface is not connected to computer

• Jul 12, 2020 - 16:44

This has just started happening in the last month or so. It took some time to figure out the connection because I didn't really pay attention to when my USB interface was in use or not.

I have tried (multiple times) re-setting MuseScore to defaults, restarting, re-installing, and re-configuring the I/O to use anything except the audio interface. MuseScore will not move past the splash screen if the audio interface is not already connected, it just gets stuck drawing around 30-40% CPU. I have left it for over an hour and that doesn't change.

OS: Windows 10 Home v1909 build 18363.900 (64-bit)
MuseScore version (64-bit): 3.4.2.9788, revision: 148e43f

I used a program called SysInternals Process Monitor to capture the behavior of MuseScore starting, with and without my USB interface connected. CSV files here. I hope that is useful.

Try 3.5 Beta or a later 3.x development build, those to send some output to the splash screen, giving information what they are working on

That's what I'm saying, for some reason it doesn't work, the files are "selected" but not getting "attached" to the post when I submit. That page doesn't tell me anything helpful.

Anyway, I have other ways to send files, I still have no clue what exactly is causing MuseScore to become so dependent on my audio interface. I tried the beta and nightly versions with no success.

I haven't solved why it happened, but it seems I've fixed it by uninstalling another audio-related app. It seems to be working again.

In the past few weeks I was experimenting with an app called Voicemeeter and it seems there was some behind the scenes fuckery in the audio devices which resulted in MuseScore not being able to start if the USB interface was disconnected.

Again, I didn't make the connection until now because I wasn't regularly using the Voicemeeter app, also not paying explicit attention to when exactly I was or wasn't using my USB interface.
