I didn't realise that. Dante describe virtual soundcard as "a standard ASIO or WDM Sound device".
If DVS doesn't work, many of the connections and audio interfaces that process multi-channel audio might not work.
AVB and AES67 are rather simpler - have you considered them?
AES/EBU is a simple interface, and something like the Lynx
AES16e AES/EBU or
RME HDSPe AES 32-Channel AES/EBU PCI Express Cards might do the job.

Edit: The
Marian Clara D might be a better option, as they claim ASIO, MME, WASAPI and WDM compatibility. It's a reasonable price, and AES/EBU is the most compatible physical interface of all.
