Any luck?
I have the RealTek Audio Console and it doesn't give the option for anything but stereo over Optical. I've gone to my motherboard's maufacturer's (ASUS ROG Strix X570-E Gaming) website and it's list the same driver as what was auto installed by Windows Update. I've attempted to obtain a drive from Realtek but their site seems to only have older drivers for older OS (and it's painfully slow)
