[Pkg-utopia-maintainers] Bug#1127422: pipewire cannot be started in --system mode

[Ralph Benzinger]

Package: pipewire
Version: 1.4.2-1
Severity: important

Dear Maintainer,

On my Debian desktop, various applications are running under a different
user than the logged in user.  Thus, those applications cannot produce
sound if pipewire is started in --user mode.

(In fact, those applications start their own pipewire instance, but since
the desktop is running under the logged in user, those other pipewire
instances have no way to output sound.)

I've experienced this behavior with pulseaudio as well, but it was trivial
to start pulseaudio in --system mode.  However, running

```
systemctl --system start wireplumber pipewire pipewire-pulse
```

yields error messages

```
Failed to start wireplumber.service: Unit wireplumber.service not found.
Failed to start pipewire.service: Unit pipewire.service not found.
Failed to start pipewire-pulse.service: Unit pipewire-pulse.service not found.
```

I agree that --system mode should not be the default, but it should be
at least possible if so desired.

[Error sent manually, since reportbug fails to send emails.]
