From Mageia wiki
cf. https://bugs.mageia.org/show_bug.cgi?id=33424#c13
NB. I followed the "Manual method" from the wiki. I found that the packages task-pipewire and wireplumber were missing.
- dnf install task-pipewire wireplumber pipewire-pulseaudio pipewire-alsa pipewire-plugin-jack --allowerasing
would do the trick at once.
