Carla patchbay screenshots, from fresh reboot to multiple applet open
SUMMARY
On my machine, I have Pipewire installed as a JACK (and PulseAudio?)
replacement. After creating a coupled stream virtual device according to
https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Virtual-Devices#coupled-streams,
plasma-pa doesn't disconnect to the virtual device after the applet closes,
even though it disconnects from the "built-in" audio devices (observed in Carla
patchbay). Also, probably because of that issue, plasma-pa creates new
connection ports each time the applet opens, with each new ports connected to
the virtual device not disconnecting and further bloating the patchbay.
STEPS TO REPRODUCE
1. Install Pipewire and Carla.
2. Create a virtual device, following
https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Virtual-Devices#coupled-streams.
3. Open Carla and go to the patchbay.
4. Open the plasma-pa applet several times.
OBSERVED RESULT
The Plasma PA 'device' in the Carla patchbay persists, with each call to the
applet creating more ports for the virtual device which doesn't close.
EXPECTED RESULT
The Plasma PA 'device' in the Carla patchbay should properly disappear each
time the applet closes.
