It's not known to me, but I haven't paid especially close attention to
audio related issues.

Before going any further I'd recommend making sure that you are using a
new enough version of Xen to be using the modern "qemu-xen" device model
rather than the older "qemu-xen-traditional" fork. IIRC qemu-xen was
available as a tech preview in 4.2 and became the default for
non-stubdom configurations in 4.3 onwards (sadly stubdoms are not yet
supported for qemu-xen).

Depending on your specific use case you could also consider using pci
passthrough to give the real device to the VM, or perhaps SPICE
(available with qemu-xen I think) provides a better audio experience (I
don't know much about SPICE, I think it does audio forwarding too
though, not sure if Win8 drivers exist though).

Ian.
