[qubes-users] non-PCI forward/tunnel of dom0 audio to VM possible?

Is there a way to share dom0 audio sources/sinks via pipewire/qrexec/??? to an audiovm so that other VMs can use them?

I use my sys-usb as audiovm, since i have usb audio devices (such as usb-bluetooth for headsets). Unfortunately, PCI-forwarding the built-in audio device to a vm cripples its functionality (see also [qubes-users] No NHLT in VMs -> no microphone?)
This built-in audio device, however, works fine in dom0, and only in dom0!

Thanks for any pointers
