New page

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. Bequimao
