Playback in 4.0 prerelease is very sharp

• Dec 8, 2021 - 01:47

Hello! I'm not sure if this is a known issue, a feature not implemented yet, or operator error, but here's what I'm seeing:

I'm running ubuntu 18.04.4 and I compiled the latest from the master branch of the MuseScore repo today, and across multiple instruments, the playback is a little over a full step sharp. I've looked through the available settings, and I can't find a spot to change the tuning for an entire project (and the synthesizer panel is unavailable).

If this is user error, I'd love to know how to fix it - and if it's a bug, I'd be happy to gather as much information as you'd need about my machine to get it fixed. If it's just not implemented yet - no rush, 4.0 is gonna be great!

To troubleshoot, I compiled and ran the 3.6.2 release and did not see the same issue, so it doesn't appear to be a general problem with my machine.


My guess is it has to do with a mismatch sample rate 44.1 vs 48 Khz, maybe different versions of the audio libraries being used are interacting differently with your audio hardware & drivers.

Thanks for the reply. I figured it might have something to do with sample rate - but I've been unable to change it within MuseScore. It's currently set to 192Khz, and when I change it the changes don't stick.

Upon revisiting that though, I see "setCurrentSampleRateIndex: Not implemented!!" in the program output when I move that box, so that might explain it. I'll see what other troubleshooting I can do both in and outside of MS, thanks!
