How many years till sonos fixes the loud pop and shutdown with Atmos???

Well I guess you have it all figured out and I am just wasting my time (and obviously your time). I’ll leave you alone. Enjoy the popping.

FYI… I use an Apple TV 4K (1st Gen) and have zero issues when playing Dolby Atmos content through my Arc. I’m actually enjoying Dolby Atmos music on the Apple TV as I type this, pop free.

I completely agree with the OP, it doesn’t matter what setup combination a person has, the only thing in common for anyone with this problem is having a Sonos Arc. I’ve spent at least a year looking for a solution and can’t believe there still isn’t one out there.

To add to that, this is a wide spread problem that can be shown by a simple search of the forums for the phrase “arc pop”, its frustrating that this hasn’t been fixed via a software update by Sonos by now. Does technical support not track similar problems to determine if this is an issue they need to address?

279 TOPICS!!! 😂 I called technical support and they wanted me to take a video of the problem whenever it happens. Which is crazy to me. Then the guy had never heard it the issue. I told him to type in “Sonos arc pops atmos” and he will see hundreds of threads going back a year with the problem. This amazes me sonos has apparently done nothing about it or even bothered to acknowledge and issue after over a year. I hope the guys who keeps asking about the setup and act like it’s not an issues are busy asking the 300 people on here about their setups then telling them they have no issues at all. 

I keep wondering if it’s not a Sonos problem, but a problem in the CEC devices in the TV sets, which are sending a valid “sound” to Sonos, then shutting down and not sending further information. If that is the case, then Sonos can’t really “fix” it, it’s something that has to be done with the Atmos specification, and how the “computer” in the TV set handles it. 

And the fact that it is apparently affecting, from what I’ve read, other manufacturers in addition to Sonos seems to point to it being less of a Sonos specific problem, and much more of a “there’s a problem somewhere else” kind of thing. 

I know it’s easy to blame the last thing in the chain...but I’ve not seen any definitive proof that it’s actually something Sonos can fix, yet. 

Would I like them to be able to recognize the event, keep it from playing? You bet...if it’s an identifiable and filterable event, but that won’t likely fix the computer in the TV set that’s likely generating the event. Or, potentially, the device upstream from the TV, that might be generating the issue, and sending it to the TV which is struggling on how to deal with it.

Just not sure how much I can put this on Sonos’ plate, based on all the various things I’ve read in those many topics. 

I don’t understand why people on here are so defensive of Sonos, its like a cult.

I’ve used other Atmos systems with the same setup and this never happened; I’ve used the Arc with other TVs and devices and it still happens, I’m extremely confident it is an issue with the MAT format with the Sonos Arc. If using a 4K Blu-ray instead, the issue never comes up, Blu-ray uses TrueHD format.

There are links to other manufactures soundbars that have the popping issue posted in other threads here on the forum, so it’s not just limited to Sonos. If you search using Google you may see the reported issue with other brands and it is confirmed by Staff here:

@mjherm,

Here are some examples of the ‘popping’ issue seen with other brands involved and so it shows it isn’t just a Sonos issue…

My thoughts are it’s either a codec issue, or a hardware issue in some TV models or connected peripherals, but that’s entirely a guess on my part. I’ve used Dolby MAT Multichannel LPCM via Apple TV to an LG OLED C9 TV, together with the Sonos Arc, surrounds and Sub and (touch wood) have never come across the ‘popping’ issue and I see why some forum users here think it maybe (just perhaps) a hardware component in the connected TV, or sending device.

If that is indeed the case, I also very much doubt Sonos would ever announce that publicly, as they are after-all partners in the industry and the last thing a company will do is hang another company’s dirty washing out to dry.

The sheer fact other branded products are also reporting the issue makes me think the matter may lie elsewhere and not at Sonos’ door.

Tried to watch Bullet Train last night and the arc popped and turned off again because it’s in Dolby Atmos.  I switched to the appletv app on my tv set and didn’t have an issue so like most people a read it seems to be an issues with players like appletv, Xbox, or whatever. Or I just got lucky playing through the apple. It seems to be weirdly intermittent because the last time it did it I was listening to Apple Music on the appletv4k and then I just gave up listening to music.  Then when I called tech support they wanted my to try and I guess sit around and film my arc until it blew out again. So I sat there and listened to the same stuff I was because an it played fine. That was until last night when it blew up during Bullet Train.
