See how long it takes for the 1st episode of 'Drive to Survive' on Netflix for the Atmos to start dropping out. I always suspected that the stream's characteristics were a factor, and that show always starts dropping out within about a minute for me. I believe that shows with a more active...

We already new it wasn’t a Marantz issue, since many other AVR brands also have the problem. What we didn’t know is if it was the Atmos decoder chip used in these receivers, since that could be the same across brands. Assuming your Trinnov Altitude 16 (and the VRROOM) uses some higher end Atmos...

I’ve frequently shared my opinion that Apple is making no effort to fix the Atmos issue. Even if it can’t be completely fixed due to hardware limitations, it can be mitigated, since tvOS 14.x was far less prone to the Atmos dropouts/glitches than 15.x. Perhaps the Spatial Audio features that...

I am on the latest tvOS 15.5 beta and manually updated all my streaming apps (they had not yet auto-updated yet), including Netflix, and the Atmos dropouts took less than a minute to show up on 'Drive to Survive'. Not sure why my apps hadn't auto-updated yet (the auto-update apps setting was...

That is a good idea! Of the channels I subscribe to, I am thinking HDTVTest would be a good fit. Vincent has 416K subscribers and is located in the UK. Can anyone in the UK confirm that the Atmos problem also occurs with UK Netflix streams? Of course any popular Apple-themed channel would be...

I do not have to deal with the Atmos issues on the Gen 2. As I have said before, I also have a Gen 1 that has never had an issue with Atmos. I have both the Gen 1 and Gen 2 connected to my Denon AVR, so I can test the latest updates on the Gen 2, and switch over to the Gen 1 if the Atmos has any...

Didn't you have an open support ticket? Request a refund. The Atmos support is unacceptable, and Apple has had ample time to fix the problem. You could use the money to buy a Gen 1 (a few places are still selling it). As frustrated as I am with the Gen 2 and with Apple, I have to admit that the...

I was hoping Apple would get the Gen 2 working just as well as the Gen 1, but that is not what I meant! There have been several similar reports on the Apple support forum. I am keeping my Gen 1 on tvOS 15.3 for now. I honestly don't believe anyone at Apple is working to fix the Atmos issue. If...

That doesn't surprise me. I never believed a network issue could cause the Atmos issues without also affecting the video. I assumed that all a network issue could do was cause the streamer to eat into the buffer a bit, potentially resulting in a lowering of video BW and image quality if the...

Thanks for the additional details. I assumed MAT 2.0 was only used to carry the Atmos metadata in the ATV4K. I am doubtful that the issue precedes the creation of the MAT 2.0 stream, as decoding issues might tend to corrupt other audio formats. I have also never noticed any video artifacts...

I am not speaking for @JonFo, but that was the clue that had me pointing my finger at the MAT 2.0 Encoding/Timing as root cause, back when @JonFo was discussing EDID HDMI issues. If it is a MAT 2.0 Encoding/Timing issue, then it will only affect Atmos as MAT 2.0 is only used for Atmos metadata.

Mostly going from an article I read months ago, I believe other streamers do not use Dolby MAT 2.0. Here is the article: The Ultimate Dolby Atmos Guide The Shield bitstreams. I don't know about the higher end Amazon devices or the latest Roku Ultra, but I doubt they use Dolby MAT 2.0. I expect...

I am sure some here have noticed that I have been pointing my finger at the MAT 2.0 encoding/timing as the root cause of the Atmos problem for quite some time now. I believe Apple is the only major player taking this approach to Atmos support. I believe all the disc players bitstream to the AVR...

But it doesn't seem to be just any Atmos + DV show -- some content seems to be less problematic. I have recently watched the first 10 episodes of 'Black Summer', a Netflix Atmos + DV program, and haven't had any issues. I had previously watched shows, such as 'Lost in Space' and 'The Witcher'...

Pleased to see someone remembered my speculations regarding the root cause of the Atmos problem. I still believe it was not far from the mark. I have been mostly on the sidelines, testing the latest tvOS betas, and switching my Denon AVR to the Gen 1 unit when there is a problem. To be honest...

I believe that is because the ATV decodes the incoming audio stream and outputs 5.1 LPCM + Dolby MAT 2.0 for the Atmos metadata. Your VRROOM is seeing the 5.1 LPCM (and hopefully not discarding the MAT 2.0 Atmos metadata that should be passed on to the receiver along with the 5.1 LPCM).

Samsung has their own version of Dolby Vision called HDR10+. Both use dynamic metadata, making them superior to basic HDR10, but HDR10+ isn't supported on as many streaming services.

Here is a link to that HDfury VRROOM. HDfury VRROOM It is $400 more than a brand new Gen 1 ATV4K, so perhaps not the most cost effective solution to the Gen 2 Atmos problem.

That is correct. The Gen 1 and Gen 2 both decode the Atmos audio stream and output LPCM + Dolby MAT 2.0 for the Atmos metadata. There is nothing wrong with this approach, and it works perfectly on the Gen 1 units. My hypothesis is that the Gen 2 Atmos problem is due to errors in the creation...

I honestly never heard the problem on my Gen 1 ATV4K. I am not going to state that the Atmos problem doesn't exist on Gen 1 units, but I will say that those Gen 1 reports are very possibly/likely a very different and unrelated issue from the Atmos problem on the Gen 2 units. Reports are in that...
