AMD HDMI no audio through Windows Store (UMP) apps
So I have been using a 295x2 for a while now and recently purchased an LG OLED (C7).
For some reason when I install the AMD HDMI audio driver I get sound through all regular apps except the store (UMP) apps like Netflix, Gear of War 4 etc. I am thinking that this may be some sort of DRM\HDCP issue but I can't pinpoint it. When I uninstall the AMD driver and just use the basic windows High Definition audio driver all sound works as intended, but of course I loose some of the advanced features of the AMD driver.
I am using a miniDP to HDMI adapter but it was working fine with my old Samsung Plasma. This only became an issue after I got the OLED. The current adapter I am using is the Club3D CAC-1180 miniDP 1.4 to HDMI 2.0b.
I currently have the 18.2.1 driver installed but as I stated earlier this has been an issue with all the drivers I have tried with this TV (since version 17).
Any thoughts or assistance on this would be of great help to me.
