I was in your shoes last February. I wrote a whole guide about it, it might be useful to you.Yes this would be great to figure out for AMD systems. To add even more confusion I have a Razer base station that has 2 USB 3.1 ports and built in 7.1 audio which seems to work. I have a ASUS x570 TUF Plus WIFI. Someone on reddit recently supposedly got it mapped but would like to learn how to make my own for my board however I lack the skill.
