Hello, I have an AMD Radeon RX 560 in my Kabylake System with OS X 10.12.6 installed, but I don't get any HDMI or DP Audio working. In the Sound Settings I see myTV where the system is currently connected to but I get no sound. When I use the Intel HD 630 then I get HDMI Sound. I tried it also on the latest High Sierra Beta and there is the HDMI Sound working with the AMD Graphic Card. I don't know if this card is fully supported on 10.12.6. I have also attache my Problem Reporting Files. Thanks.
