Hi, I'm hoping for some help in understating my options - and hope this will help may others too. Challenge: connecting the new apple TV 4k to (1) a 4K Television, and (2) a high end AV receiver that does not have 4K pass-though. note: I don't want to replace receiver - it is an $1800 unit that contains excellent amps and near magical trinnov room correction processing - and is just too expensive for me to retire. The problem is that this older receiver - a newcastle r-972 - supports only hdmi 1.3 - and no ARC In all older apple TV generations - (without 4K video to accommodate) - I would connect the apple's TV's HDMI to the receiver, allowing receiver to extract the audio, and then pass the video through a further HDMI cable to the Television. In the apple TV 4K, - I can't connect only to the receiver because it would not pass though the long awaited 4K vidio signal to my television. Options that come to mind. An audio extractor box (that supports 4K hdmi2.0) would give me a digital audio output to feed my AVreceiver while HDMI goes on to television. But better audio formats like Dolby True HD, DTS master HD don't work over spdif / toslink / optical port. I thought this would be a deal breaker, but the sadly, the apple tv 4K does not seem to support these higher audio resolutions either. here's an example of the audio extractor box I was looking at: http://a.co/0M7dQwt A better option would seem to be to adding an external 4K HDMI splitter - essentially adding a second HDMI out that the apple tv should have had in the first pace - one goes to TV, the other goes to the AV receiver. Does this cause handshaking / hdcp issues? Maybe this approach would help future proof system in case apple adds better audio support in future. Here's one box that happened to come up in a search that looks like it would work: http://a.co/1StTtCb (description is confusing though - is it really 4k?) What do you guys think? Any other options, and/or supporting hardware recommendations you might have? Thanks, and good luck everyone!
