[macOS] Speakers crackle loudly when other apps play audio

Hello all,

Recently musescore released an update that fixed audio issues with Musescore 3 on Mac OS. Most of the issues are fixed except for one - seemingly at random, playing audio in YouTube, Music (or for me Roon) causes the speakers to crackle loudly whenever the audio is played with musescore open in the background. The only solution is to restart Musescore. Sometimes the crackling can get so bad and loud I'm afraid it'll damage the speakers permanently. Obviously, this isn't totally on Musescore as the T2 is still unstable but it's the only App this happens in so I don't know what else it could be. I haven't yet figured out a reliable way to reproduce it. It seems to happen when MuseScore is open for a longer session and I play audio on an unrelated app. Let me know if anyone else is experiencing this.


For me, some crackling happens whenever I open musescore while playing some other audio. The crackling isn't very loud though.

Interestingly, the crackling happens basically consistently with youtube, Xplayer, VLC and Rhythmbox, but does not appear to happen at all with spotify.

I have musescore 3.2.3 on Linux Mint 19.1 Cinnamon with Xplayer 2.0.2, VLC media player 3.0.8, Rhythmbox 3.4.2 and spotify 1: The issue has been around for a while, probably going back to musescore 2.0.1 or similar, back when I started to use musescore.

Status active needs info

Can anyone affected by this please provide the
a) MuseScore version
b) macOS version and
c) hardware model description from About This Mac
so that someone who is not aware if they are affected by this can try and reproduce.

Could possibly be related to autosave. See if the problem goes away if you always are careful to save your work before switching to another app.

Version 2.0.3 isn't supported any more. If you really want version 2 still, I suggest you upgrade to 2.3.2 (the last 2.x version) but 3.5 is so much better once you learn how to use it.
