[Solved] Musescore Jack crashes with Pipewire

Using latest stable Musescore, either the AppImage or the RPM version : if Musescore is configured to use Jack, it crashes after loading a score. Unusable.
A workaround is to configure Musescore to use Alsa or PulseAudio, but you lose Jack syncing with other apps.

pipewire-0.3.22-4.fc33 & mscore-3.6.2-1.fc33

The only hint is this system log from sender pipewire

  • (mscore-40) client too slow! rate:1024/48000 pos:8421376
  • alsa-pcm 0x55fe07fc2648: snd_pcm_status error: Broken pipe

My bad. I changed the sampling frequency in the config files to 48000, but let them in comment.
Removing the comments, so that they are explicitly set and everything works again

Issue is still not solved on Musescore side Musescore 3.6.2 crashes when opening score with Pipewire/JACK | MuseScore
It my never be, since most users are on Windows anyway.

I lost the exact Pipewire config that allowed to work …
