Welcome to the forum!
If you want to use MC, I think the only way is to record the physical output of your audio interface (take a lead from output back to input). How it works, depends on your audio interface. AFAIK, DAWs seldom have live stream record capability built in. That's not what they're designed for.
Otherwise, there are several inexpensive or free recorder software for the purpose.
www.kvraudio.com is a good Place to search.
If you're using the PCs integrated soundchip, you might succeed by choosing "What-U-hear" or "Stereo mix" as the
recording mode, but I'm not sure.
