Out of curiosity try with 15000000
. That's what I use on my ASUS board with the same controller. Also check you've not got alcid=x set in the boot args as they'll conflict.
I'm starting to give up.. everything was working fine before I reinstalled osx...
I tried to insert my old rx 570 , to use a monitor that I had before upgrade... also tried without usb headphone..
tried every possible id, nothing works :/
acording to Dortania, this shouldn't look this way :
