[doublepost=1523759225][/doublepost]I have a similar problem with my 2016 LG OLED TV and an older Arcam AVR400. The AVR400 is a very nice amp and equivalent replacements are in the £2700 price range. The AVR400 won't pass through 4K over HDMI and so I need to use the AVR as an audio processor only. I've tried ARC and toslink/spdif out on the TV to the AVR, but ended with hard, distracting, intermittent dropouts (and ARC in general seems to be a mess as it requires enabling CEC and then all sorts of weird stuff starts happening).
I've found 3 potentially viable solutions:
1. https://hdfury.com/product/avr-key/. This $149 device provides one UHD passthrough and 1 HD HDMI output from a single UHD input. This will let me route the audio to the AVR and send the video unadulterated to the TV.
2. http://www.octavainc.com/HDMI switch 4x1 ARC port_pro.html. This is a $249 4-1 UHD HDMI switch which allows routing of audio out via toslink, (which I would send to the AVR). This device has the advantage that I could consolidate all my sources to a single HDMI output to the TV.
3. AppleTV 3 / Airplay. I have a couple of these kicking around so $0. I can hook this into the AVR as an HDMI (or optical using toslink) and route the Apple 4K TV audio to it. I think the 2 sec delay might be a bit of a drag.
1&3 feel hack-ish. 2 is expensive but enhances the overall setup ...
I'll start with 3.

So how did Option 3 workout? I'm curious to give this a shot once I get my ATV4K.
