HDMI Handshake Issues with GTX 1070 and Pioneer Receiver - No Issues With TV

[unscripted1]

I will give full specs below, but here's my issue. About two months ago I started having what I can only assume are HDMI handshake issues with my PC and my receiver. The obvious question is "what changed?" so the best I can think of is I keep my Nvidia drivers up to date resulting in several updates and of course the Windows 10 creators update jacked with a bunch of settings but I think I've properly reconfigured. What happens is that every 8-15 minutes the audio and video will cut out for roughly 2 seconds and then return. This is only happening on my PC, I don't have this issue with my 4K blu ray player, PS4 Pro, or XB1-S.

My setup is PC to receiver via HDMI, receiver to TV via HDMI (all quality 2.0 cords that I've tested thoroughly). I tried pulling the HDMI from the receiver and moving it to directly hook up to the TV, problem solved, but then I lose 5.1/7.1. I know optical is an option, but since I only use it for gaming I will need special decoders for surround sound with most games and it'll be lossy and not lossless PCM like I get with HDMI. In short, I'm trying to get this thing to work via my receiver to not lose lossless 5.1, 7.1, and potentially Atmos in the future. I am working with 4K resolution, but all of my components are compatible with compatible cables (HDMI 2.0a, HDCP 2.2, I even have HDR working via PC). I played through all of Shadow Warrior 2 and RE7 in 4K HDR with 5.1 uncompressed on this setup, it's all compatible. Again, I'm only gaming, no multimedia playback. Here are my specs:

PC: Gigabyte GA-H81M-H LGA 1150 mobo, i5-4690K (not overclocked), Gigabyte GTX 1070 G1 Gaming OC, 16 GB DDR3 RAM - HDMI (using 2.0 cable) for A/V, output 4K60 @ 4:4:4, 5.1 surround in sound settings.

Receiver: Pinoeer VSXLX-101 with HDMI 2.0a/HDCP 2.2, compatible with 4K60 4:4:4, HDR, and Dolby Atmos.

TV: Samsung KS8000 65" with HDMI 2.0a/HDCP 2.2, compatible with 4K60 4:4:4, HDR (and yes, I've got UHD Color "on" to activate these settings)

Any ideas? I've had this setup for a year and the only thing has changed are the Nvidia drivers and the Win10 update. If you suggest rolling back drivers, which ones? Anyone have a confirmed driver number that doesn't have this issue?

Update: Turns out that the solution was to remove the HDMI cable and then re-attach 15 minutes later. Alternatively me swapping the cable to the TV and then back again fixed this as well (although I had to reboot Win10 once). A buddy of mine was telling me there may have been sync issues of some kind, but the best solution is to power down all devices, remove the HDMI cable, re-seat it, and power everything back on in 15 minutes or more. Shockingly, that worked.
