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.
 
I’m in a similar situation, and can’t believe how few choices there are. Almost everything I find only supports HDCP 1.4, but I finally found one that supports 2.2 (for HDR)... so I just ordered it:

Based on reviews, it sounds like exactly what I need: 4K HDR to the TV, and 5.1 surround sound to my ancient receiver via optical. I’ll find out on Friday!

I faced situation like this a year ago. And finally decided to let my fancy Class-D receiver (STR-DB2000) give way to a contemporary HDMI-connected and Atmos-capable STR-DN1080.
Here, missing out on the modern audio formats was the main driver, not that much the HDMI connectivity.
Which at the end of the day is just a bonus for me.

So, there must be a good reason to hold on to your "ancient receiver". What is it?

PS my DB2000 is still in use, just not as the main media center.

A combination of things, I suppose.

It’s an old Samsung HTIB I bought from a friend years ago. It’s very short (height I mean). My Xbox One sits on top of it. The rest of my TV stand is completely filled with the rest of my gaming consoles, and center speaker. All “real” receivers are quite tall, which would leave me with nowhere to put the Xbox.

Beyond that, I would want new speakers as well, since I’d want to upgrade to at least 7.1 surround. Also it’s in the corner of my apartment living room, and getting to the wiring behind the TV and everything is immensely frustrating. Especially trying mess with the speaker wires, since they are just barely long enough due to me running them under the carpet and such. Like they’re so perfect I can’t even pull the current receiver out more than a few inches.

I was very tempted to get a new receiver a little while back, but I’m glad I didn’t, because it was right before the whole 4K HDR thing. So I’d have to upgrade yet again, haha. But now I think if I get at least a 7.1 or 7.2 with 4K HDR capability, I’ll be set for quite a while.

So I’m just holding off on the real home theater upgrade until I buy a house. The hunt is already in progress.

Hello, I just took delivery of an Apple TV 4K and am hoping to use the same device to drive my oldie-but-goodie Denon 3805 receiver. Did it work as you had hoped?

Until an hour ago, I had a Vorke HD41 Pro with v8.4 firmware that wouldn't take the audio. I should have heeded the reviews on Amazon warning against upgrading the firmware (there's an 8.5 on the Vorke site), but didn't and now I have a useless brick...

I'm sending video to my even older NEC 50XR4 plasma (1365x768, yay)...wish I could replace it, but it refuses to die :)

From my personal experience the HDFury product has solved this issue for me and is awesome. I decided to go with the Vertex as it had two inputs. One for my Nvidia Shield and one for my ATV4k. It switches between inputs depending what I am using and one output to my TV for video and another output to my AVR for sound.

The Vertex is a bit more expensive but It works best. They have another product called AVRkey with a single input and is less expensive.

Also on side note, they strip away the HDCP :)

They also have amazing support on the avsforums.

It did not work. I kept getting flashing black screen constantly, and lots of static sound. I ended up just buying a new receiver for $229 at Best Buy. Much better!
