AppImage : Issue with Jack on Linux Debian 9
I've downloaded the AppImage of Musescore3 for Linux.
I launch it and all is fine with pulseaudio or Alsa, but with Jack as audio backend,
there is no sound. I can't open the synthesiser from the 'View' menu.
It happens every time I use Musescore3 AppImage.
Musescore 2.3.2 is installed on the same computer and works fine with Jack, PulseAudio or Alsa.
