Pardon the delay, but from some testing this appears to work.
I have other minor issues with sound in windows but I can't rule out
timing or other issues. I was able to make things work by turning off
audio driver acceleration.

Adding nointxmask=1 worked! With no issues at all. I think because all
the devices are getting their own interrupts (on the host) anyway.
So do you want me to try to add the card to quirks.c? I could probably
manage it, just I haven't compiled a kernel in ~50 years.
Great! I think the below should work for a quirk, if you can manage to
build a kernel and try it (removing the nointxmask option), it would be
much appreciated. Thanks,
Alex
