devices

SUMMARY
When on Linux selecting Pipewire or PulseAudio (with Pipewire host) it never
shows any virtual devices.
As i use a 2 Pc setup my mic needs to be in the other pc, i just send it over
via tcp.
Same with my speaker its all plugged into my streaming pc and my gaming pc gets
to share the devices.
Im using virtual devices for that, so on my gaming pc i have my default device
as "game" a virtual speaker that gets send over to my streaming pc.
But i can only select physical audio devices.
How do i make kdenlive be able to use the virtual devices / can you make this
so it works.
Seams strange that this has not come up jet,
there are a lot of setups where people will use a virtual device to output to
all attached speakers.
STEPS TO REPRODUCE
1. Be on linux with pipewire working
2. Set audio driver to pipewire or pulseaudio
3. See that you can only use physical audio devices
OBSERVED RESULT
Only lists physical audio devices
EXPECTED RESULT
Should list all audio devices, virtual ones included

ADDITIONAL INFORMATION
The audio connection can be changed in qpwgraph but kdenlive will always go
back to a physical device on statup.
As info for my virtual devices setup, there are a few files at:
~/.config/pipewire/pipewire.conf.d/
As example my default virtual device is this file "10-game.conf" and has
contents:
context.objects = [
{ factory = adapter
args = {
factory.name = support.null-audio-sink
node.name = "game"
media.class = Audio/Sink
audio.position = [ FL FR ]
audio.channels = 2
monitor.channel-volumes = true
adapter.auto-port-config = {
mode = dsp
monitor = true
position = preserve
}
}
}
]
This make one of my virtual devices
