Netflix Dolby Atmos problems with new Apple TV 4k

I have done the same, though I have both the Gen 1 and Gen 2 Apple TV 4K units connected to my Denon AVR so I can easily test the latest tvOS versions on the Gen 2. I don't have much hope that Apple will ever fix the problem. I essentially have a $200 remote control upgrade for my Gen 1 ATV4K.

No. The Gen 1 has never had an issue in the same setup as the Gen 2 "upgrade" that was intended to replace it. The Gen 1 unit has always been on the latest public release of tvOS, and I am currently upgrading it to the just released tvOS 15.3.

When I went to Apple with the Gen 2 Atmos problem, they replaced it with a new unit, which was on tvOS 14.7. With the replacement Gen 2 unit, the Atmos problem was very infrequent, perhaps once every 10+ hours. However, after upgrading it to tvOS 15.2, it would have audio ticks to complete dropouts that required restarting the stream, perhaps as many as a few times per hour.

I gave up and reinstalled my 2017 Apple TV 4K (and paired the new gen remote).

So far 2.5 days later still no drop outs or other issues. So I hope this continues.

FYI all hdmi cables were replaced, manipulated, and sent to diety to be blessed. Nothing helped but I now know a heck of a lot more about HDMI cables.

Same problem here. I have the ATV 4K 2021 + Denon x4700h + LG OLED C9.

i have the dropouts not just on netflix. it’s also on itunes movies. so definitely not just netflix.

Just upgraded to the tvOS 15.3 and i could watch half of an epsiode with 1 small dropout. so it seemed to get a little better.

BTW: i also have the Shield TV pro and no issues there with Atmos. But in all honesty, the unstable/ not correct working auto-framerate function, was the reason for me to buy the ATV. so not any single box out there right now, which is perfect :(

I am returning my Shield this weekend for this reason. I just installed a new set of issues with the frame rate as you said. If all else fails I will re install my old Apple TV 4K and put the new one where Atmos isn't needed. I am on a support chat with Apple right now, if enough of us escalate this maybe it will get fixed!

Let us all know how it goes....i hit a brick wall with Apple Support but i plan to keep watching this forum and once i see they have fixed it and if my new Shield still has a buggy Frame Rate beta option, and is still stuck on Android 11, maybe I will give Apple another chance!

Tell the rep about this group it will save you some time. I was on the phone for 4 hours before I found this page. FYI I ordered a Monoprice 8K Certified Ultra High-Speed HDMI 2.1 Cable - 3 Feet - Black | 48Gbps for the ATV to the receiver, and it seemed to clear up a bit. I ordered another one (ten feet) for the receiver to the TV. Fingers crossed.

Let the rep know about the group and all that has been discussed here. They are taking it to engineering and getting back to me this weekend. I have full video of this happening repeatedly and sent that in to them as well. I have full 8k high speeds on everything right now. Thought it would alleviate some of the issue, it didn’t.

The Atmos problem is random, so whether tvOS 15.3 appears

better or worse is of no significance, especially after our short time with it.

What is important is the fact that the problem is still present, which suggests

that not a single line of code has been changed to address the problem.

Hopefully, tvOS 15.4 will be a different story.

Confirmed. Problem still exists in 15.4.

It now mutes regularly for half a second for a while (typically with a lot of audio it seems)

But, when it starts to stutter, it stutters BIG. For quite some time.

The AV receiver display changed quickly to I think pcm, then back to Atmos during that half a second.

This was tested with Netflix "drive to survive". The race part at end of season 1 - episode 2

Once it starts stuttering, keeps coming back every minute or so. Getting more and more frequent. Sometimes display av receiver has all speaker output indicators off and dolby sign off for brief moment.

Then, also the quieter sections keep chopping up.

Completely unwatchable. Perhaps this issue is not on Apple's radar after all. Seems to be getting worse.

Definitely not only Denon. My Onkyo does it and I picked up a Denon and that does it as well. The Denon is better, but it’s still there. I am still waiting to hear back from the engineers at Apple. My ticket is still open. It sounds like they know there is an issue.

So I received my HDFury Vrroom and reinstalled all my hardware. Vrrom now splits the HDMI video and audio signal to different HDMI ports with arc/earc HDMI 2.1 functionality. But the Vrrom is very expensive.

Before I had sound dropouts with TV+. I watched Palmer and a show in 4k and Dolby Atmos, yesterday. Without any dropouts, so far. It looks like it handles the handshakes very well.

Maybe the new setup fixed it. I tested only TV+.

Can someone suggest a good movie in 4K and Dolby Atmos on Netflix?

So I watched The Silent Sea in 4k and Dolby Atmos without any dropouts

My settings:

Format: 4K SDR 60 (59.94Hz)

HDMI Output: RGB High

Match Content: Match Dynamic Range -> on and Match Frame Rate -> on

Audio Format: Auto, Atmos Available

So this setting will switch automatically to 4K HDR YCbCr 422 with 12 BPC and 24Hz

I think the HDFury fixed my problem. I love that device.

This coming weekend I have more time to watch a movie again.

The Silent Sea for me after 10-15 minutes stuttering starts.

But also, the framerate seemed off right before the stuttering.

No black screen switching framerate so seems the video playback was also having issues. Restored after the stuttering was gone.

No changes on the AV receiver's display this time

Can someone check the hdmi-firmware version on the gen 1?

Go to settings-info press 'down' once

I'm on 1.136
