Audacity will record multi-channel now. There are several devices with special software arrangements and the ability to lay down multiple tracks.

I don’t know that the Behringer will work natively since I believe Windows will naturally try to mount the device two-channel stereo.
You should avoid settings and software that use the word “ASIO.” ASIO is a special software environment that Audacity doesn’t easily support.
Have you ever compiled a software program? If not, then ASIO is not in your future.
