I’ve had the Sonos Arc since October and safe to say I’ve had this popping issue happen to me on multiple occasions at this point. I thought it was an issue with my Xbox Series X but seeing that people are having similar issues on the Apple TV makes it seem that this is definitely a Sonos issue. Hopefully that fix comes out sooner rather than later. 

I’m of the apparently minority opinion that the ‘pop’ is being generated upstream from the Sonos device, and the Sonos device is merely playing what it is handed. That being said, I’ve seen no compelling evidence in particular, other than it appears to be associated with Apple TV and Microsoft XBoxes. 

Happens with my Roku Ultra as well.  It has now happened to me 3 or four times in the last few weeks.  Very annoying and I hope Sonos fixes the issue soon.

I think the problem is that it isn’t a Sonos issue, so Sonos can’t really ‘fix’ it. It has to be fixed upstream, before the ‘pop’ is being sent to the Sonos. 

The issue is occurring across multiple type of streaming devices and TVs.  The common device between everyone reporting the issue is the Sonos.  Granted this is a Sonos forum, but what would lead you to believe that another device is causing the issue?

Because it doesn’t happen on all systems, for instance on mine, which are Vizios, and all reports seem to be centered around either XBox or Apple TV devices. If it’s limited to specific types of device inputs, and doesn’t occur across all types of TV sets, that suggests at least the possibility that the event is occurring upstream from the Sonos device. 

In the past, when there has been an issue with Sonos, they’ve been pretty clear about admitting it as a cause, and indicated that they were working on the issue. At one point, there was a thread with thousands of posts from users of the PLAYBAR that were experiencing an issue. So far, Sonos has not said anything about this issue being on their side. 

None of that is definitive proof, mind you, but I would also assert there is no definitive proof in these forums that it happens to be a Sonos issue. You’re certainly welcome to draw your own conclusions, and would likely be as accurate as I am. I’m open to any potential solution to the problem. But, if it happens not to be a Sonos software issue, I logically can’t expect them to fix it. If it is indeed their issue, I expect them to own it, admit it, and rectify it. So far, none of those items have occurred. 

I have the same problem since a few months now. Xbox Series X; Sony XH900 with Arc + ONE SL + Sub.

my support file: 1523225932

So I ran into the issue twice more over the weekend (one from ATV and one from Xbox) and I noticed a pattern starting to emerge.  I have the issue occur in bunches and then after a hard reset of the Sonos system it goes away for a month or two with no other resets in between

I am wondering if the working software isn’t experiencing some sort of memory leak as after a reboot it’s rock solid for weeks on end and then happens two and three times in a single evening

Same problem here; system is less than two months old. Loud popping noise started a couple of weeks ago, only occurrs when XBOX Series X is in use. So far I have not had the issue using any other source. What seems to trigger the issue in my case is switching between apps on the XBOX (from a game to spotify then back to the game or when switrching to the youtube app on the Xbox).

Using newer belkin cables for both the apple tv and Arc. 

Anyone know if Sonos S2 v. 14.0 fixes this popping issue? The update just dropped today and I know Sonos was developing a fix. 

Time will tell — I thought the same after the last update.

I think the truth is, the installation just includes a reboot of the Sonos, which commonly—but temporarily—fixes the issue.

I have just spent an hour or so on xbox series one x playing a couple of games that were guaranteed to ‘pop’ with Atmos enabled and it hasn’t happened so far again, since update. But will reserve judgement just yet in case its related to the reboot as part of the update to v14.

Fingers crossed though!

I can confirm that Sonos 14 hasn’t fixed the issue, neither has tvOS 15.3.

Just experienced the issue minutes after starting a purchased iTunes Movie on the Apple TV.

Update: So still no popping after many hours of xbox series X and atmos enabled, playing the games that previously would pop without fail (Forza Horizon 5, MS Flight Sim, Cyberpunk 2077). I also watched a 4K bluray with an atmos soundtrack and no pops. I never had issues with other sources such as my Apple TV 4K or the inbuilt apps on the Sony A8J and thankfully still don’t. Still keeping fingers crossed and hoping its solved it but why for me and not you Jamie I don’t know :(

It worked for 3-4 days and all the sudden the pop happened again. The update didn't fix it for me.

Yeah, same old same. Reboot normally alleviates the issue temporarily.

What I haven’t got around to testing is if multiple different formats causes the issue, and there’s some memory overflow somewhere i.e. if you watched DA content continuously, and not flick between 5.1, etc., would the issue continue?  

Same problem here, loud pop noise.

Sonos Arc, Xbox series X and LG G1.

Everything has been updated to their last SW. This is so annoying…

Sono team, can you please let me know if I can do something?

Thanks,

Hi all,

To throw my 2¢ in here, as I've read the entire thread after experiencing issues (daily) myself, I'm running a very similar set-up to many of you:

Sony Bravia X90H

Xbox S, Switch, Arc, PS5 (in order of HDMI 1-4 slots)

The popping noise has only come about when playing Xbox, and was happening 2-3 times each evening. I opened a ticket with support during the day, and after getting home power cycled the Arc as well as swapping out the HDMI cable (just in case) before submitting a diagnostic.

Support said things looked good on their end, but I imagine what did the trick more so was disabling Auto HDR on the Xbox. After turning that feature off I had no sound disruption at all last night, even after ~4 hours of gaming. I'll post an edit/update if they come back, but compared to the last few weeks that's already a vast improvement. 

One thing I'd like to note is the rep stated I may want to remove all other HDMI devices plugged in to the TV when using the Arc, which was an... interesting suggestion. Not sure I'm willing to use the Arc only when using streaming services via my TV. 

Similarly, kinda, is that I changed from 4k50 SDR to 4k50 Dolby Vision in my Apple TV video settings last night.  Made it through The Book of Boba Fett without issue, but will report back if anything *does* happen in the near future.

Mainly because it seems that whilst the Apple TV 4K (2nd Gen) is advertised at supporting DV over AirPlay for Photos, it only seems to work if the video output is DV by default—it won’t “upgrade” SDR to DV when starting an AirPlay stream (as it would everything else).

Whilst I can’t comprehend why video settings would affect audio; AV stuff, tracing all way back to good ol’ RF signals, is a tricky beast.

Hey, 

I add my contribution to this topic too. Couple of months ago I heard this loud bang and low volume after that first time, when watching Dolby Atmos and Dolby Vision content from Apple TV 4K. Turning on TV speakers and then bacl to Sonos fixed the problem, until I heard it again when using xBox Series X and again Dolby Atmos content. Total of 5 times. Today, early morning when watching Viaplay from Apple TV 4K I had multiple sound cutouts, that got fixed by ”hardbooting” the app, but when I turned tv on later today, Sonos is complete silent! No matter what source connected to TV  I use (Playstation 5, xBox Series X, Nvidia Shield Pro, Apple TV 4K, or TV’s internal apps) there’s no audio at all. Alexa on Sonos arc works fine, also when streaming spotify from iPhone everything works. But via TV, it’s all silent 🥺

Sonos Arc + sub.3gen + 2xPlay:1

Sony 85X90H

I won’t claim to be knowledgable enough to know why it seems like so many of these issues are more tied to video output than audio, but it does seem to be the case, doesn’t it? Just theorizing but maybe something to do with how the information translates over the eArc channel? I have no real idea, just spitballing.

Tangentially, since my first post I’ve played… a lot of Xbox (new purchase for me and loving Game Pass). I haven’t had any issues at all since turning off Auto HDR. Still curious to know what the real underlying reason is, but given how much I played over the past week I’m ready to consider the problem settled for now.

Made it through another episode of Book of Boba Fett — so testing continues.

Out of curiosity, of those with Apple TV, what is your current video output setting?
Additionally, for those experiencing on Xbox, do you have “Auto HDR” enabled?

My Arc has done this several times. It happened 3 times this morning! So frustrating!

I experience the same. Xbox Series X - Atmos… Signal comes via eARC from an Sony XH9000.
