I still stand by my Dolby MAT theory – it’s the only consistent point between Apple TV and Xbox Series X. 

Hi @MartinStartin…

You perhaps need to contact Sonos Support direct, as the Staff may not pick up everything here in the user community. Here is the LINK to contact/chat with them online. Hope you get the issue resolved soon.

There is, devices that use the Dolby MAT container for Atmos (Xbox, Apple TV and now Roku).   There was some debate before as to whether the TV passing through the MAT signal was doing it properly and since I’ve had failure with two different TVs now.  I’m more confident it has nothing to do with the TV passing through the signal but the signal itself

@LiL FiL,

I reckon that almost every report I have ever read about this ‘popping’ issue mentioned online in relation to Soundbar’s (not just Sonos ones, but others brands too) that somewhere in the HT setup, is either an XBox or an Apple TV-4K (or both) - those two connected products seem to be a common denominator and it’s certainly happening with other manufacturers Soundbars, if you look online. It makes me wonder if it’s not a Sonos-owned issue??

It might also ‘perhaps’ explain why Sonos is not making any public comment about the issue, if it is partner-related.

The challenge may be, and I’m guessing here, that it’s not a Sonos issue at all, but something that’s being sent from the TV (although that may not be the origination point, I don’t know). If that’s the case, Sonos is merely playing what they’ve been told to play, and it’s the switching upstream by some other device that’s causing the issue. 

I do tend to agree with @jamie_shaw that the predominating factor in all of these, beyond Sonos itself, is a MAT container, which suggests the potential above. 

And if that is the case, Sonos is unlikely to call out publicly who the responsible party is, since they’re on the “we want to be friends with everyone so they’ll interface with our system” train.  

All I can say for sure is that I’ve not had this issue on my system, which is indeed driven by an Apple TV through a Vizio TV to a Sonos Arc. But that doesn’t mean it’s not happening at all, just means that there’s something else going on, and it may not be an endemic issue with Sonos itself. 

Just chiming in that the issue still keeps happening for me too, regularly, on Xbox and Apple TV. Sony 900H TV. 
 

Nothing has helped. Sonos support is giving me the same run around as the rest of you so I’ve stopped calling. Mission accomplished for them I suppose.

Asking for a recording. Pretending they are not aware of it being a widespread problem. Wanting me to establish if it happens with the Sonos music app (who cares?). Etc. 

This has been my theory for a long time — between Apple TV, Xbox and Roku — it’s the common denominator: Dolby MAT.

Hi @Pahakissa 

We’re not aware of this issue happening on Beam, though it is related to Atmos. Therefore, we would appreciate it - if it ever happens again - if you could immediately submit a support diagnostic and later get in touch with our technical support team so we can document the occurrence. We’re also not aware of this issue causing any actual damage to the units it happens on.

We have lots of reports of both Xbox and Apple TV being affected. And these are widespread devices from major manufacturers, so it might just be their popularity causing the reports. 

Likewise we have lots of reports from both Sony and LG TVs passing the signal. Again, major popular manufactures.

On the other hand, we only have reports of Sonos devices being affected. Granted, this is a Sonos forum. But nobody is linking to similar threads about other sound bars and any request for examples is avoided. 
The weight of the evidence is pointing at a solution having to come from Sonos. Yes, maybe the Atmos spec is somehow not being followed by the major content players and TVs, but even if (if!) that is the case, it’ll still be on Sonos to fix it in software if they want to keep selling devices. I know I have stopped buying further Sonos devices until my Arc can play Atmos. 

I just came home with a brand new Arc and set it up with my Samsung S95B.  I enabled Atmos on my Series X and everything appeared ok.  
 

I loaded up Overwatch 2 and less than a minute into the game…“POP” and the sound cut off.  :|   I quit out of the game and there was another smaller pop and then the audio returned. This is very disheartening. 
 I was aware of this issue from browsing the forums but was hoping I wouldn’t be affected or at least not often.  
 

I captured a diagnostic and called Sonos support and they basically just said since my sound had returned the issue was fixed and if it happens again to call back.  They seemed very dismissive of the popping sound/cutoff occurring which is obviously what the concern is. 

I don’t know what to do now as far as keeping or returning.  Again this is very disheartening after spending $1000.    I’m already scared to leave Atmos enabled but and not sure if it’s worth it without it. 
 

I know this has been a long standing issue but is there any acknowledgment or confidence that this will be resolved?

 

Has anyone tested the Apple TV 4K 3rd-gen with this issue yet? Thinking about picking one up today or tomorrow to see if the issue exists with that combination of hardware, I did try a bunch of config changes to my setup and had the pop happen within 30 minutes again

This is exactly correct. As soon as I disable Dolby Vision, Dolby Atmos works perfectly without any popping, as soon as I enable Dolby Vision on Apple TV, pop within 7min, every time. Hard reset repeat, always occurs. I was a QA Tester for Sony, and this what would be classed as an “A” Bug. It is reproducible. And it always initially occurs with an Xbox Series X. Prior to last week, when I got an Xbox Series X, I had zero issues with my Apple TV no matter what the setting or content. As soon as the Xbox Series X was played with Dolby Vision and Dolby Atmos, this error occured. After which, the Apple TV 4K began to have issues and is now permanently having issues. So Brian, this IS a Sonos issue, as once the error has occurred from initial Xbox Series X connection, now any Dolby Vision and Dolby Atmos combined from any source, Sonos Arc can no longer function properly.

I tried the “disable Dolby Vision” on Apple TV and still had the pop occur when playing Atmos yesterday

Be prepared for people on here to attack you claiming this isn’t Sonos’ fault and they have nothing to fix or even acknowledge 

Been constantly checking with the Sonos support team who say they are aware of the issue and it’s also persistent in other sound bars. The only option is to disable Atmos content and go for 5.1 instead. After selling one of my kidneys to afford the Arc + Sub + Surrounds, my other kidney is calling me a politician for promising some of that Atmos content and not delivering.

Is everyone down to email the CEO? ceo@sonos.com is the address given on the contact page. Not sure what else we can do?

I’m not sure if you read what Rowley_1 said, “This must be a Sonos Atmos issue.” Denoting this IS a Sonos issue/ fault.

From what I’ve read on this topic in multiple posts, the only people being  “attacked” and criticized from others are people who claim that this IS a Sonos issue. And just as Rowley_1, (and the vast majority of everyone else who posted), said, “Not acceptable for any product, let alone one that costs this much.”

We are all awaiting solution/ update fix. What is the point of having a TV capable of Dolby Vision and HDMI 2.1 Dolby Atmos when the component that we all purchased is unable to process the signal that it’s advertised to process better than other 2.1 sound systems?

I submitted a diagnostic report last night and spoke to support, they acknowledged the issue exists for many and they have a team gathering info to work on a resolution, I provided details of the different TVs and devices I’ve experienced the issue on

I can confirm that I switched off Dolby vision 2 weeks ago. I haven't had a single issue since with Atmos. Just wanted everyone to know!

I have a 2022 Samsung S95B which like you mentioned does not support Dolby Vision but as I posted a couple pages back, had the issue occur with this setup on the first game I tried with it on the Series X after hooking up my Arc. 
I do have HDR10 enabled but even without Dolby Vision it still occurs on my Samsung so I don’t think it’s linked to that, at least not exclusively. 

So Sonos what is the solution if I want Dolby Atmos on my ARC? Hello? Are you there? 

I know this is a community. But I'm frustrated. Please, read all comments from the beginning of this thread. Then there are probably 50 more threads about this problem in this community. The community has called support, reported and also emailed SONOS CEO. But nothing happens for more than a year. What is going on?

So we have Corry P employed at SONOS who likes the post above.
Are these the answers we will get from SONOS?

Corry P has been very active today on the community. With lots of written responses to other threads. But we get the thumbs up on a post.

Incidentally, I was at 9 dealers today. No one absolutely no one mentioned that there might be problems with Apple TV or Xbox if you want Dolby Atmos.

Sonos it's time to give us an answer. 

I had my same set up (Sony 900H, Apple TV4K, Sonos Arc, Sonos One Surrounds) for over a year with no issue ever. Then last spring, out of the blue: BANG. Then it popped every 15 to 20 minutes after that while watching Atmos Content. Sad. 

I turned Dolby Vision off on the Apple TV and left Atmos on, no issues so far. Any loss of Dolby Vision enhancements are not that apparent to me.

I appreciate Atmos and sacrificing Dolby Vision was not a big trade off for me. 

Yes, we’re all unfortunately in the same boat. This issue has been known for over a year, with no fix, no update and no support.
