"Multichannel Output" Profile disappeared after I ran JACK (ardour),
and I only see again now on a fresh startup.

Do you mean it disappeared from pavucontrol when you run JACK from
ardour ?

What I meant is that you cannot run pipewire and jackd at the same time
? I cannot work as one will prevent the other from accessing the ALSA
sound device.
If you want to run JACK application whne running pipewire you can only
do so by pipewire-jackd and disabling jackd. 
This is not a pipewire bug. jackd also cannot work if the sound device
is already taken by an alsa program or any other daemon plugging to the
alsa interface (pipewire, pulseaudio), it could work because for one
pulseaudio aut suspend itself from time to time so the alsa sound
device is free when so. But then when pulseaudio will resume and your
jackd daemon is holding on the alsa sound device pulseaudio will not
work. This is not supported (for pulseaudio you could use the pasuspend
tool, still it is  hack).


Also:
Gnome Settings Output Device contains nothing to select, while Input
allows "Analog Input - STUDIO-CAPTURE" and "STUDIO-CAPTURE Pro". The
only way to have output audio working is to use pavucontrol and select
either of the STUDIO-CAPTURE Profile Configurations "Multichannel
Output", or "Pro Audio".  
and:
That "Multichannel Output" Profile disappeared after I ran JACK
(ardour), and I only see again now on a fresh startup.
seems to be two different issue. You should report both in two diffrent
bug report else it the bug report will get confusing soon.
My reply was about the second issue (which to me look like a normal
behavior).


For the first one, I am a bit confused. You mean that even in
pavucontrol if you do not switch to the STUDIO-CAPTURE Profile
Configurations "Multichannel Output", or "Pro Audio" you cannot set a
sound output device?

If you bug report upstream you could try to run pipewire built from
source (you just have to stop pipewire related systemd user services,
ie systemctl --user stop pipewire.service, etc).
Also there is a newer pipewire version 0.3.76 in Debian rc-buggy
(experimental).

Could you provide the same debug logs as this bug reporter did?

loginctl user-status | grep State
lsof /dev/snd/*
fuser -v /dev/snd/*
aplay -l
journalctl --user -b --unit pipewire.service

and maybe also 
journalctl --user -b --unit pipewire-pulse.service
pipewire --version


and why not the output when running gnome-control-center from a
terminal:
gnome-control-center --verbose sound

Still could you try with pipewire-jack instead of jackd (even if you
prefer to run jackd only while running a jack application.

Cheers
