Audio in a pass through GPU PC

I purchased the Gigabyte Gaming 5 AX370 and ryzen 7 1700, to follow wendells guide for GPU pass-trough, after a few drawbacks I was able to do it, but I do not know how to get Sound for the Windows 10 Guest, I have a Scarleth 4i2 USB Audio Interface. I was thinking in pass-trough a USB controller, but I am not sure if that is possible without affect other things.

Can someone help me, or give me any idea?
