Which driver (and instructions given a new Windows install) do I install for ROG Strix Z270E-Gaming.
The Audio is described as: ROG SupremeFX S1220A 8-Channel High Definition Audio CODEC
In the details of the manual, it lists Sonic Radar III and Sonic Sound III
So, looking at MokiChu's Realtek page, I think it's the second one?

I do not plan on installing anything except the driver (ie, no Sonic Sound III etc) - not sure I have to do any of those uninstall steps unless Windows 11 preinstalled them as part of setup since the device seems to be installed as "High Definition Audio Device"
