5.1 microphone adapter?

I have a Vive Cascade 5.1 microphone that is meant to work with video cameras. I have tried a couple of cheap usb adapters that claim 5.1 compatibility, but they only apparently provide 2 channel input from the mic. Hours of googling has not revealed a solution. Anyone know of an adapter that will provide 5.1 input from the mic into a windows 10 pc? Thanks!

According to one of the reviews the Vive outputs Dolby Prologic, which encodes the surround information inside the 2-channel stereo signal. So any normal 2 channel input will work.

It's up to the audio decoder/player to separate out the surround channels.
