ARC does not support DTS-HD or Dolby TrueHD. Only eARC does.

For any HD audio, you need eARC. Or a new receiver that supports HDR.

 

But that receiver surely doesn't support eARC either, correct?

 

From what I found, it seems only ARC and not eARC.

 

You can buy an HDMI splitter that will enable lossless to a legacy AVR. Can't recommend one as it can't be any old one as it must be able to down convert to HDMI 1.4 along with dealing with the EDID. HDfury devices are almost certain to work but are expensive. Personal opinion better money spent in upgrading AVR then band aid solutions for an old AVR. Money tight, search the used market for an HDMI 2.0 AVR as long as no need for 2.1.

 

I know for my LG OLED(G1), DTS isn’t supported at all, even pass through via eArc

 

I have that problem with my DVD player / TV / Sound bar connections. I have a Shield pro, but the HDR sources for streaming are DD+(Atmos) that will go over ARC. The DVD player has separate HDMI outputs for video and sound, so I can send the sound directly to the sound bar, and the HDR video to the TV directly at the same time.

 

So I guess I am relegated to either a) the Shield rendering Dolby Vision and HDR if plugged into the TV and missing out on any DTS-HD content or most of my multichannel audio files or b) plugging in the Shield directly into my receiver, getting all of the aforementioned audio but losing HDR and Dolby Vision capability. Unless I want to shell out more money for a new receiver with eARC capability/HDR and Dolby Vision capability. THAT'S not frustrating. I'd be more apt to spring for the receiver if I didn't just spend so much on wiring the room, mounting surround speakers, the tv, etc.

 

You can also use a HDMI audio extractor or HDMI splitter.

 

Yes, you can purchase a AVR Key by HD fury. Should be about $150 USD. It will have one input and 2 output. 1 hdmi output to tv and 1 to receiver. Basically it sends full video signal to tv and a 1080p or 720p black screen with full HD audio to receiver. You will lose the receiver's OSD. If you do not care about audio quality, pick up a cheap 5.1 HDMI audio extractor from Amazon. If you do care about HD Audio, get the AVR key.

He doesn’t need a HD Fury. He can just use a HDMI splitter/audio extractor. $30-40 on Amazon. The audio quality is exactly the same, it just passes through the digital audio. It is lossless.

 

You better off spending the money towards a new receiver. If it's incompatible with your needs and requirements why bother to get some other device and make it complicated?

Simplest solution new av receiver.

 

I know that's the simplest solution (a new receiver). But I have an OLED that can handle Dolby Vision and HDR and the receiver can handle DTS-HD, etc. The receiver also has Zone 2 capability which I use for my whole home audio setup. And it's 90W per channel for this big room. Any newer HDR/Dolby Vision compatible receiver with that much power is going to cost A LOT. If there is a more cost-effective solution I would prefer that since this isn't my main home theater room.

 

So the NVIDIA shield would plug into the splitter and one hdmi out to the tv, one to the receiver?

 

Before you do any of the hardware purchase, check to see if your Kodi is properly configured. I have major issues with eARC to my 5.1.4 soundbar, but can still play DTS-HD and TrueHD rips with no issue over ARC. I set up my Kodi by following the instructions in this post in the Nvidia Shield support forum:

Not saying this is a solution only it worked for me.

 

Art Vandalay?!?! Hilarious. Too bad 6 other people took that name before you.
