My Apple Tv 4K not providing the Dolby Atmos Sound.

High speed Belkin HDMI cable (recommended by Apple).

It is a bit more subtle than that. ‘High Speed’ is a very specific designation for HDMI cables. I think you have been recommended ‘Premium High Speed’ or better for 4K HDR:

HDMI 1.0–1.2 cables: “Standard” (rated for up to 5 Gbps);

HDMI 1.3–1.4 cables: “High Speed” (10 Gbps) – (Apple TV (4th generation) has an HDMI 1.4 port to match);

HDMI 2.0 cables: “Premium High Speed” (18 Gbps) – (Apple TV 4K has an HDMI 2.0 port to match);

HDMI 2.1 cables: “Ultra High Speed” (48 Gbps) – Note that there is no consumer equipment with HDMI 2.1 ports yet, to make use of all that bandwidth.

Some cables are not up to spec, and may perform poorly. Cables with quality control/guaranty/warranty should perform as advertised. How much bandwidth actually is needed, is food for a different post. Belkin has a history with Apple equipment compliancy; so Apple knows to expect good cables from them.

Set the Apple TV Audio Format to Dolby Atmos.

That option would only be available if a capable receiver is detected. It seems you are almost there.

The document also provides some caveats to make it work, so don’t skip the small gray text (Quick Start, ARC).

Yes, my Sony gets a little hot but no problem, its cold in Norway. The fix worked, now Netflix and iTunes show the ATMOS logo on compatible films.

" Dolby Atmos worked when Quick Start is turned from on to off and back on, in Settings. To check, go to Settings > Apps > iTunes Movies and TV Shows > Quick Start. Then restart Apple TV."

You will have to connect the Apple TV directly the to the AV receiver by HDMI – not to the TV, as Dolby Atmos from Apple TV requires more bandwidth than ARC can offer. “Most televisions don’t support Dolby Atmos pass-through to sound bars and receivers,” and “Apple TV 4K uses a high bandwidth form of Dolby Atmos that doesn’t work over ARC connections. [1]”

Maybe you have done so, but it is not in your setup description.

Don’t go by trailers, as there is no rule that the trailer AV quality will match the feature film. It can match, but it doesn’t have to.

Dolby Atmos may not be available for alternate languages. Likely only for the primary (original) language audio track.

I experience the same and believe it or not it was my cables, they worked okay with my 4k Sony Player but would not provide enough bandwidth for my apple 4k, upgraded the cables and not problems since.

I have finally found the fix it was just a simple setting on my Apple TV I now have lovely Dolby Atmos

You can't play sound in Dolby Atmos if Quick Start is turned off in Settings. To check, go to Settings > Apps > iTunes Movies and TV Shows > Quick Start.

Ok guys.... I had geek squad come out and do a "basic audio setup" for $140. It was by far the best money I've ever spent because now I'm getting Dolby Atmos for the following....

-Netflix-(All Atmos content)

-Vudu app/Apple TV

-Vudu app/Samsung-M8500 (streaming)

-Amazon Prime-Jack Ryan (surprising)

----NO iTunes* (unfortunately)

I'm okay getting no Atmos on iTunes because before Geek Squad came out I wasn't receiving "ANY" audio for Atmos content through the 4k Apple TV.

Please keep in mind that the information I'm going to post is only plausible for my experience and my specs.

Glad to hear it man!

FYI... I took back my Onkyo NR-787 and upgraded to the Pioneer LX-503 Elite and when I did that Dolby Atmos automatically worked with ever iTunes movies "rented & purchased"!!! With the exact same setup as the Onkyo.

Onkyo and Pioneer are made by the same manufacturer so it makes no sense to me how compatibility works in odd scenarios such as this. Geek squad was just as perplexed as to why these settings work for the 4k Apple TV...

All I know is I got a better receiver and now I get Dolby Atmos in every format that is offered via 4k Apple TV.

I've heard great things about the Sony STR-DN1080. However one audio specialists at Best Buy said they may tend to run a little hot. Does yours?

Lastly, just curious, with your Sony were you able to access Dolby Atmos via "Vudu, Netflix, and iTunes"?

I have exactly the same problem, when my Apple TV is set to Dolby Atmos my Denon Amp Just sees it as multi in. My amp works with Atmos from my Blu Ray player. I have swapped cables and still get the same results.

Hey man I just saw your post. I just posted this yesterday. I think we're having the same problem. Have you found a solution? The "Solved" answer that you received hasn't worked for me.

It's obvious that you have to go 4K Apple TV to receiver......then use ARC directional cable to the TV to have any chance at activating Atmos.

From my receiver I have in "HDMI 1" the recommended Apple Belkin cable (from 4k Apple TV) and then I'm running Audioquest "Chocolate" via ARC from receiver to TV. Still no luck on iTunes or Netflix getting Atmos.

(Compatible AV receiver/4k Apple TV/Dolby Atmos)

So I'm having trouble accessing Dolby Atmos from iTunes and Netflix ONLY from the 4k Apple TV. I have the following specs for my Home theater. I'm running a 5.1.2

Everything works great except for trying to access iTunes or Netflix Dolby Atmos content. I was easily able to access Dolby Atmos with the same 4K Apple TV when I had a Samsung N950 soundbar. Using the Belkin Dolby Vision HDMI cable.

Here's the real confusion.......I am able to access Dolby Atmos through Vudu on my Samsung M8500 Blu-ray player.

The receiver responses and turns on Dolby Atmos.....just not on the 4K Apple TV. I believe it's a receiver problem.

Does anyone know of a foolproof AV receiver that accesses Dolby Atmos and DTS-X in iTunes and Netflix on the 4K Apple TV?

No I still haven’t got it working. I bought a belkin 48Gps cable to see if this would help but still no joy. My receiver works with all other Atmos devices just not Apple TV. It just shows it as Multi in

Thanks, tried everything else without any results.

You'r fix worked. Mine was turned on so I turned it off then on again, restarted apple tv and Netflix was running Dolby Atmos.

I'm using a Sony STR-DN1080 receiver and it works perfectly with Apple TV 4k.

Good to know that another receiver like your Sony will work for all Atmos apps.

I remember reading a full article on your Sony receiver but it was posted in 2018 and was never updated before Atmos was compatible with 4K Apple TV so I didn't get it.

I also did not toggle back and forth with quick start and then reset Apple TV. I just made sure that it was turned on as well as Auto description off etc.

I guess I should have read the Dolby Atmos page on Apple support better.

Thanks for the specific QuickStart info! Glad to know we're both on the other side of it.

Very helpful post. Thank you. Bummer iTunes isn't working with the Onkyo.

I can go back and review the thread, but is ARC a show stopper? If so, do I simply run my Apple TV 4K through HDMI 1+?

Onkyo 2018 Receiver (not sure of the mode, but it supports Dolby Vision and Atmos)

Hopefully Onkyo has a firmware fix, if I can't get it to work with iTunes. Otherwise, I think I'm stuck.
