No sound out of MuseScore 4.x (4.11 4.4.4 4.5.2)

Description with steps to reproduce

OS: Linux 22.04
No sound on playback.
pkill pipewire-pulse allows the playback cursor to "progress" but no sound under any circumstances.

Pipewire must be installed because the DAW uses it and it would be a pain to uninstall / disable for MuseScore and risk losing the ability to use the DAW altogether, and beside, it's not a given that Pipewire is the issue, just a suspect. MANY musicians will be using Pipewire for audio and will have more than one audio program installed.

Would be nice to have simple, basic sound on MuseScore -- doesn't have to be fancy sound, just any sound at all.

This problem did not occur with MuseScore 3.6.2 or 2.3.2.

To reproduce, simply run the AppImage on a Linux operating systems:
MuseScore-Studio-4.5.2.251141401-x86_64.AppImage*

What is the latest version of MuseScore Studio where this issue is present?

4.5.2

Regression

Yes, this used to work in MuseScore 3.x and now is broken

Operating system

Ubuntu 22.04

Additional context

Pipewire is installed. Bitwig Studio, a powerful and expensive DAW, demands it to work, and disabling it would be risky (might create hours of effort to get it working again).

MuseScore 2.3.2 works fine with this system configuration, but is quite old.
