MuseSampler fails to initialize on non-systemd Linux distributions

Issue type

General playback bug

Description with steps to reproduce

I created the following VMs:

• Fedora 43 (systemd)
• Void (runit)
• Artix (openrc)

All 3 VMs were running KDE Plasma and a Wayland session.

I started the process by downloading MuseSounds Manager (TAR) and the MuseScore Studio AppImage. I then:

1. Launched MuseSounds Manager and installed the same sound on all 3 VMs.
2. Exited
3. chmod +x ./MuseScore-Studio-4.6.5.*.AppImage
4. ./MuseScore-Studio-4.6.5.*.AppImage
5. Verify

Only the Fedora 43 VM worked as expected.
