Simply press Ctrl+F to look for you adapter in the "Render" root (just check adapter's name in the status volume bar or else), open FXProperties and delete "MULTI" keys starting with "d04e05a6". No need to do anything more fancy...
Yes, having the same issue. UAD installed automatically over classic driver and created a "Realtek Audio Console" in my modern apps list. That one doesn't work either.
