Spews out a lot of stuff, the relevant part being presumably:

Here the sinks say just:

Hmm... this time a web search lead me to

    systemctl --user status pipewire{,-pulse} wireplumber

which shows that `wireplumber` failed to start.
Thanks.  Haven't found the actual problem nor a fix, but I have
some leads.
Stay tuned, I'll be back with the results :-)
