updated my Apple TV 4K to tvOS 17… so far no popping… let us pray  

You're right cause my PS5 plays DD+ blurays with no issue.

yup

Nevermind.. its back with a vengeance… back to 4k Firestick I go

Im actually a bit relieved as Xbox also acts up and if it’s on their end I’d say there’s zero hope of a fix. 
 

Well, time for Sonos to step it up. 
 

Engineers are paid the big bucks. Time to earn it. 

Especially if it is not a Sonos issue, but something upstream sending a ‘pop’ signal to Sonos, which is just playing it as instructed to by the CEC system / decoder in the TV set, or the MAT encoder in the device itself. 
 

Come on, Sonos, you have control over all the other companies in the world that are part of the CEC alliance, and control their engineering time, right?

Welp. Just started having popping issues with my arc. Started with a few very loud pops during the Apple Keynote, which to no surprise, was using Dolby. Have also started having this when using Xbox, which according to this thread is also not surprising. Really disappointed, as I have only had it for a few months now and never had any issues during the return period.

My setup includes:

- Arc + Symfonisk Surrounds + Sub Mini
- LG C2 OLED
- Apple TV & Xbox Series S

I tried turning off CEC and power cycling with the TV and Apple TV, which seemed to help for a while. But came back on the Xbox as soon as I switched over. Guess I will also disable CEC on the Xbox and try again. 

It's wild that this has been going on for so long with no solution. Makes me kind of regret getting into Sonos, after loving it for so long. 

Tomorrow is the 3 year anniversary of the Sonos Arc. At this point, I’m chalking this up as an inherent design flaw of the Arc and that this issue won’t be resolved until the release of the Arc 2. If it hasn’t been fixed by now, it probably never will…

Unfortunately, that's exactly how I see it. I really don’t know what I should do. I'm on the verge of selling all Sonos products, simply because I don't think Sonos is bothered to solve the problem.

I don’t blame you for thinking about selling. I still enjoy my Sonos system overall, but having deficiencies when watching Atmos content is very disappointing.

Maybe. 
 

But if that’s true they sold a product as Atmos certified only for it to be incapable of doing so. I don’t care if it only has issues with MAT. It’s their responsibility to release a product that works as described. It doesn’t say “incompatible with MAT” which puts them as the accountable party in these issues if it cannot be fixed. 
 

The funny part is I have yet to experience this on an Apple TV 4K even when using Dolby Vision and Atmos on both my Arc and Gen 2 Beam. It’s only been my Xbox. I’m sure it’ll happen on my Apple TV soon enough but I don’t understand why I’ve had the issue with Xbox but not Apple yet. 

I don’t know if you even want to do this to yourself, but the most reliable method I have for triggering the pop is to fire up the “Hits in Spatial Audio” playlist on Apple TV Music and letting it run. Almost always pops within 30 minutes. But you can just let it go while you’re not even in the room and return to it later checking if the Arc has entered the “on but no sound” state after a pop.

Hello there, beautiful people of this nefarious and long thread. Life´s too short and SONOS customer care, engineers and everyone involved at least for the matter that gets us here, are a bunch of AH that couldn´t care less of us and our “new problem that just developed and OMG our engineers just heard about and OMG we have them in our dungeons with no food and little to drink until they solve this ultra new and rare issue for you, our beloved customers”, so I took a very nice offer that SENNHEISER recently had on their website and now I can happily say I can actually hear whatever I like without any popping, banging, ringing or whatever. Super rare that the APPLE TV and the PS5 no longer have any issues and work as they´re supposed to...super super rare. I still don´t know what to do with the POS soundbar that now lies quiet and still in the cold hard floor of the guest room, I can´t resell it without any guilt. I took the legal action but I know it´s gonna take a looooooooong for that to even start with the first hearings. I wish you all well and hopefully someone at SONOS has a sudden attack of conscience and guilt and actually does something or at least comes clean and says “you´re right, this thing will not work on...”. I´ll keep you posted on the legal action. Have a good one.

Wow, that’s amazing! Who would have thunk?!

Correct. Since the AMBEO has 4 HDMI ins I played a little to se if it changed anything or something happened. First all connected to the TV and TV to soundbar…nothing, all ok. Then I did it the other way around…nothing, all ok. I left all connected to the soundbar and works like a charm, all CEC enabled and working smooth like mountain fresh snow.

Xmas miracle in June.

It is time Sonos sorted this Dolby Mat issue for Apple TV and Xbox out, I can use the HDFury Arcana which does fix the issue. But sadly it introduces other issues with my Samsung Qled.

Wait. If using the HDFury Arcana fixes the issue, doesn’t that mean the issue isn’t in the Sonos, but in the TV itself?

I doubt it. The thread has people with all brands of TVs having the issue. Also, most people have their TV set to passthrough, so the TV shouldn’t really be doing anything (as I understand it at least). 

Heh, I hear you, but ‘should be’ and ‘are’ are wildly different. And if using the Arcana ‘fixes’ the issue, it sure seems to me to point the finger upstream from Sonos. What that does is effectively remove the TV set ( and the CEC computer in it) out of the equation. 

If you say you don’t have a conflict, I will take you by your word.

For those of us not really interested in combing through 35 pages of this, is there a solution or anything that needs to be done for anyone who experiences this issue?

I’ve had my Arc since launch with no issues ever, and just started seeing this issue relatively often

Pops with an Arcana? Thanks for contributing that information!

Any update on the Pop? Lg c2 with Xbox seriesX and era 300s. Getting pop when playing Dolby atmos on series x

Any luck with the 15.5 update?
