Hi,
I use sys-usb as audio VM,
[user@dom0 ~]$ qvm-prefs video audiovm
sys-usb
and everything works fine.
Now i want to migrate from pulseaudio to pipewire:
[root@deb12-template]$ apt install pipewire-qubes pipewire-audio pipewire
wireplumber pipewire-alsa libspa-0.2-bluetooth
Now sound [still] plays nicely in sys-usb:
user@sys-usb:~$ pw-cat -p /usr/share/sounds/alsa/Front_Right.wav
and pavucontrol shows all hardware (also bluetooth headset etc.).
But the app VMs (such as 'video') are silent. pavucontrol 'Control' tab
shows no cards (it should show qubes vchan sink and source), same with
user@video:~$ wpctl status
...

There are many pw nodes registered, only one (number 28) says qubes:
user@video:~$ pw-cli ls
...
id 27, type PipeWire:Interface:Factory/3
object.serial = "27"
module.id = "21"
factory.name = "endpoint-link"
factory.type.name = "PipeWire:Interface:EndpointLink"
factory.type.version = "0"
id 28, type PipeWire:Interface:Module/3
object.serial = "28"
module.name = "libpipewire-module-qubes"
id 29, type PipeWire:Interface:Node/3
object.serial = "29"
factory.id = "10"
priority.driver = "20000"
node.name = "Dummy-Driver"
...
id 36, type PipeWire:Interface:Node/3
object.serial = "36"
factory.id = "18"
client.id = "32"
node.description = "Dummy Output"
node.name = "auto_null"
media.class = "Audio/Sink"
...
What is missing? How can app VMs connect to my audio VM via pipewire?
