Passing through thunderbolt devices?

Can someone please help me with passing through thunderbolt?

I'm running the trial at the moment with the intent of effectively passing through pretty much everything as a windows 10 workstation but also allowing me to run a small Nas server independently of windows within the same box.

 

I've managed to do all the usual, pass through GPU, USB, NVME storage etc and it seems to work well.

The clincher and biggest concern for me as to whether this will work and lead me to purchase is passing through my audio interface without a significant stability/latency penalty. 

 

I have an Asrock x570 phantom gaming 4 motherboard with the manufacturers PCI Thunderbolt add in card.

From the add in card I have > Startech thunderbolt 3 to 2 adaptor >  Universal Audio apollo 8 audio interface > satellite DSP device daisy chained off the back of that. 

 

In case anyone is wondering the adaptor is manufacturer approved for adapting the sound card to TB 3 and has worked without fail in to my laptop for some time.

 

When I try to pass through my TB card I get the error "internal error: Non-endpoint PCI devices cannot be assigned to guests"

I can pass through the actual audio interface like a normal PCI device which seems to work for the most part but does seem a little temperamental, and does of course mean i need to have the interface turned on at boot, which wouldn't normally be the case.

 

I must admit I haven't had much luck passing through my USB 3 controllers either but this is higher priority right now.

 

I saw something about black listing. Might that be the way to go?
or is there some kind of override to pass a none endpoint device through?

 

18:00.0 is the interface

1c:00.0 is the Satellite

Every reference to TB 2 is the adaptor.

 

The add in card itself only has 2 ports.
