kvm allows to forward both pci and usb devices into virtual machines.
For usb its limited to usb1 but for playing back 2 channels, that
should be enough and it can be configured without restarting the host
(afair).

Or you could do a minimal jack+jacknet setup on the host and send the
audio from guest to host via network.

I don't see why it shouldn't work. But if your host doesn't provide
RT to the guest, why go the hazzle with the guest?
