I've recently built a PC to be used as a HTPC in my living room. The PC is connected to my Yamaha RX-V675 receiver through the HDMI port. When I watch movies the video intermittently goes black but the sound remains. This is fixed by powering the receiver off and then back on. The receiver has a few other devices connected (cable box, PS4, Fire TV, etc..) and none of them have this problem. I've tried different HDMI ports on the receiver to no avail. The PC is running Windows 10 but it did the same thing when I had Ubuntu 16.04 installed as well. The latest display drivers are installed.
The CPU is an AMD A8 7600 A-Series APU with the Radeon A7 GPU built in.
