This one will do exactly what you are trying to accomplish. (4K HDR to TV and Audio to old AVR)

For many, simply getting a new AV receiver instead might be a reasonable option. But for me, my hdmi 1.3 receiver cost a boatload of cash, and its audio quality remains excellent. So investing $149 in the HD Fury product to essentially extend its life does make a lot of sense.

ARCHER and CUBES suggestion to use an OPPO 203 is also interesting. The Oppo is among the highest regarded audiophile Bluray players - and in those circles is a bargain at $550. The Oppo has dual HDMI out, and a "in" for your choice of steaming device. Like the hdfury above, it has a HDMI 2.0 port for connecting to the latest UHD TVs and projectors, and an HDMI 1.4 audio port for connecting to older A/V receivers.

Beware of the many other splitters, like the $35 one from sewell direct and many others. They list spacs of hdmi v2.0, 4K, etc. their specs, but the moment you connect the second HDMI out to your older AV receiver, it will sense the lower HDMI version, and reduce output to BOTH signals to non 4K - essentially turning your new Apple TV 4K machine into a gen 4 machine.

Thanks for the conversation and solutions - Macrumors.com rocks! :)
I have the Oppo UDP-205 and have my Apple tv connected to the HDMI input. I connect my projector directly to the Oppo since my AVR does not do 4k UHD. The Oppo has an audio only HDMI to connect to my AVR. It is really quite good. I would have gotten the 203 but wanted the dedicated stereo DAC.

You cannot use ARC as a normal audio output. [...] ARC does not support HD audio (eARC in 2.1 will).

I am using ARC as a normal audio input without issues. My 2017 LG OLED C7 TV is definitely passing Dolby Digital Plus (DD+) over ARC back to my 2014 Denon AVR-X2100W Receiver.

I have reason to believe this TV would also pass Dolby Atmos over ARC, but since my receiver doesn’t support it I have no current means to test.

A normal audio source is connected to a receiver input, not output. ARC is not normal.
 
You could try using a cheap 4K splitter plus a cheap EDID manager/feeder.


This is what I ran into this week. such a waste of time.

The cheap $35 splitter doesn't work I got one yesterday such a waste of my time.

ARC is completely normal. You connect the HDMI output of your TV to a receiver audio input. The receiver doesn't have to do anything but decode the audio.

This whole thread is baffling. Your receiver doesn't have to support ARC in order for it to work as an audio output from a TV. Support on both ends is only required for two-way data on a single cable, which isn't the setup needed here. Its audio limitations are also basically the same as the audio capabilities of the AppleTV in general, so you're missing out on next to nothing by using it instead of a splitter or audio extractor box.

eARC will add some of the more complex surround formats, but most streaming apps don't support them in the first place.

That would not be ARC.

ARC means connecting to an HDMI input of the TV to pass the audio back to the receiver.

ARC means audio return channel. It is bidirectional, so that TV audio can be returned to an AVR from the single connection to the TV, when using the AVR as the source switch OR, as in this case, the AVR is bypassed in order to get 4K video into the TV, so that the TV is used as the source switch. The ARC channel is used only for audio, because the video has already been delivered to the TV via another HDMI input.

All that is required is to connect a suitable audio output of the TV to the AVR to pass along the audio. On some TVs, the HDMI ARC connection can feed audio back to the AVR from any source. On other TVs, you have to use an optical or coax digital output to connect to the AVR. But in either case, if a TV is ARC-enabled, there is a way to get digital audio fed into the input of an AVR from the HDMI inputs on the TV, whether or not the AVR supports ARC.

If the AV receiver does not support ARC, it doesn't look for the audio signal on the HDMI ouputs. Since it doesn't look for that audio signal there how is it supposed to be able to see it and decode that audio signal to make it into sound from the speakers?

Both the TV and AV receiver have to support ARC, and you have to make sure that you hook up to the right inputs/outputs. If Monitor 1 HDMI out on the AV receiver says ARC, and Monitor 2 HDMI out does not, then you have to make sure to hook up to Monitor 1 HDMI out. If HDMI input 1 on the TV says ARC, but HDMI input 3 does not, then you need to make sure you are hooked up to HDMI input 1 on the TV.
 
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!

I had to do the same thing in the bedroom for a bit...

Connect the ATV to the TV and run an optical cable from the TV to the receiver. Done.

hmm I have never thought about running the ATV through the Oppo. Use dual HDMI on oppo with the Audio going to the AVR (would also be the audio source for when you play a blu-ray on the oppo), and use the same HDMI on the TV for playing a blu-ray, but change the source on the oppo to "input" or whatever it is called to switch to that?

I actually prefer to split audio/video when the option in there. In my experience lip sync can be a bear when going through the AVR with audio and video. I feel like all high end devices need the option to split audio and video
 
but change the source on the oppo to "input" or whatever it is called to switch to that? ... In my experience lip sync can be a bear when going through the AVR with audio and video.

I have the older Oppo 105 and 105D (which aren't 4K), but use them to switch between various inputs. My 105D takes my DirecTV signal via "HDMI Back" and has two HDMI connections to my Yamaha RX-A3000, one for audio and one for video. My Panasonic Plasma is then connected to the A3000. I found that the Darby processing on the Oppo of my DirecTV signal gave me a better picture.

Upstairs I use the front input of the 105 for my Apple TV. Audio from the Oppo goes to Sennheiser wireless headphones and video goes to the TV.

I use a Harmony remote to switch inputs on both Oppos if I want to play a Blu-Ray

I have never experienced any lip synch issues, even through the longest path: DirecTV > Oppo > RX-A3000 > Panasonic Plasma.

As others have said about their receiver, my a3000 does just fine with the audio. Obviously it doesn't do 4K switching. It also doesn't do Atmos (I think they didn't update the model to support it - although it is a 7.1). Not sure if I want (or can) do Atmos, so I can wait a while before I replace it, since it cost about as much as the TV.

I'm waiting for the closeout prices on the 2017 LG OLEDs when the 2018 OLED models come in. I'm not that interested in the improvements in talking to my television, as per the preliminary comments about the new LG models at CES last week. My current interest is in the LG OLED65E7P which was $5k in June, went to $3999.99, and is now $3499.99 at Best Buy. A a drop of a few thousand more and I'm in!

Since sound quality really matters to me, rather than replacing my Yamaha RX-a3000 I'll just replace my 105D with the 205. If you look at audio bitrate numbers for 1080p Netflix and Amazon Prime (and I think iTunes) movies they are in the 300 Kbps or less region, and this is for 5.1! [I assume it is the same for UHD. If someone has the developer HUD installed on their 4K Apple TV I'd love to know what numbers they get when streaming UHD content!].

The only way that I know to get decent audio (DTS-MA) on a 4K source is with a UHD disk, so that means I pretty much have to replace the Oppo to get a 4K blu-ray player. I also want that headphone jack and MQA support (which the 203 doesn't have) so that means the 205.

So my plan is to connect my Apple TV to one of the Oppo 205 in ports (either "HDMI front" or "HDMI back"), and DirecTV to the other. The Oppo will send the audio to the Yamaha, and the video to the LG OLED.

I know Darby is controversial, but I freaking loved it when I had the 103D. I wish it was on the 203 :(
 
Simple solution for those of us with older receivers with no 4K pass through.

Connect a optical cable from your TV to your receiver. Done.
 
The lease expensive option ($50) I have found is this device:

https://smile.amazon.com/gp/product/B00YT6V9A6/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

I have had it about a week and it works well. The only downside is I have to switch the input on my receiver as it always defaults to the optical. So for now I switch whenever I have 5.1 content as the optical does a good job on stereo.
Buy a Harmony remote. It'll start up all your devices and set them to the required setting in ONE press
 
Indeed. Easy.

You are correct that it is easy but the quality is not as good especially if you have DD True HD and DTS-HD BluRay rips playing through Infuse or similar. Netflix 4K also sounds much better directly through the receiver. So until I decide to replace my receiver this is working very well for me.

I will have to compare the sound difference at some point, but for now it sounds amazing and crisp going through the TV to receiver using optical cable. These 4K TVs are capable of passing DTS.

Yes, but with HDMI not optical.

Okay I finally bit the bullet and replaced my receiver. I got the Yamaha RX-V383BL. It was on sale for $219 and I could not pass it up. Works great with the Apple TV 4K and passes HDR perfectly. The upscaling is also very good (better than the ATV4K?). If anyone is interested in the $50 switch to use with their old receiver send me a PM.
