I’m not sure what licensing restrictions there might be to reuse any
of it, but it shows one way to build a UAC2 for a PCI device.
Well, there's a bit of a terminology issue here. That's not a UAC2
driver. That's an AVStream driver for a PCI audio device. UAC by
definition means "USB" Audio Class. I suppose it's not impossible that
this could be used as a basis, but the processing would be quite
different. UAC2 in the general case is greatly more complicated than
the typical PCI audio device.
