I am using a BIOSTAR X370GTN with a Ryzen 5 2400G and I cannot for the life of me get HDCP to work according to Windows. Using HDMI into any of three different displays I have, when I go to the Audio Devices and choose the display, and check under Supported Formats all that I can see is 'HDCP: NOT UNSUPPORTED.' When I test using my workstation with an R9 Nano it works fine. Assistance would be amazing!
PS. The end goal is to setup the 2400G build as my HTPC, and using HDMI connect it into my entertainment center. Currently, when I attempt to enable Dolby Digital Atmos for Home Theater I get and error. Dolby support said that it was caused by HDCP not working.
