New receiver, no HDCP, Apple TV 4K and more queries...

Whilst not being up to date and neither HDCP 2.2 compliant or capable of 4K Passthrough, I am considering purchasing the Onkyo HT-S3505 5.1 second hand as have found it for a really great price!!
I currently have a Sony BDV-E370 Blu Ray player including Amp feeding 5.1 channels. My Apple TV 4K and other devices are connected to the TV’s HDMI inputs and the Blu Ray / receiver is connected using the ARC HDMI port so this is sending audio back to the 5.1 system. This is all good with the exception of speech sounding muffled and very quiet through the centre speaker.

So I’ve been looking at a replacement system and noting that my existing Sony Blu Ray 5.1 system doesn’t support 4K passthrough or HDCP 2.2 I thought hey why not go for the Onkyo HT-S3505?

Im figuring that if I connect the Apple TV 4K to the Onkyo amp, it will not passthrough the 4K video and audio signal from its HDMI out to my TV due to (A) not being HDCP 2.2 compliant and (B) not supporting 4K passthrough?

I thought that to get around this, I should follow the same HDMI setup that I currently use and that is connect the Apple TV 4K to my TV so that I at least achieve the 4K video and use the ARC output HDMI to the Onkyo receiver and I will at least still qualify for DOLBY TRUEHD and dtsHD - does this sound right?

In an ideal world Id spend more money but this is not always affordable and for £72 / $94 this is a no brainer.


Thanks. :slight_smile:

I think that’s the standard audio setup and the way that ARC was meant to be used. That’s how I have it wired up to my sound bar.

I’m just curious, how does infuse interpret Dolby Atmos 7.1?? Does it transcode to 2ch stereo or DTS, AC3 or AAC etc??? Infuse plays my 4k rip just fine and shows that it’s playing Atmos 7.1, but what does my sound bar see when it gets the audio feed?

FYI, if you are using ARC, the best audio you can get is lossy 5.1 Dolby/DTS. TrueHD, DTS-HD MA, and LPCM (more than 2 channels) will not be supported.

So I gather the Onkyo receiver will not play content from the Apple TV if its plugged into the receiver via HDMI and then into the TV from its HDMI output? Or will it downsample the video to 1080 but still play the audio in DolbyTrueHD or DTS MA?

It’s likely the Apple TV would simply only allow you to select 1080p as the max output resolution. Anything you play in Infuse that is 4K would be downsampled to 1080p.

If connected directly to the receiver, you would be able to take advantage of the lossless audio options as described here.

Would something like this work?

To split the HDMI signal from the Apple TV. 1x HDMI going to the receiver and the other going to the TV

I was in similar situtation - LG B7 OLED that supported 4k 60hz Dolby Vision, Apple TV 4k & Pioneer AVR that supported only 4k 30hz passthrough (no HDR, no DV). I thought of buying new receiver, but ended up buying this AVR Key 18Gbps | | Connect and Fix everything in HDMI since it was quite recommended on AVforums.

If it’s only 4k passthrough you are after, then go ahead and buy the splitter. But when it comes to HDR & Dolby Vision (basically anytime you get close to 600MHz signal), I always regret not buying the new receiver. With the AVR key there are quite a lot HDCP handshake issues even with recommended HDMI cables. If you’ve got content matching ON, then the the moment you play HDR/DV content there is 20% chance that the HDCP handshake will fail, the TV will then not recognise the signal and you will have to manually reset AVR key with a button.
