I was playing on my Xbox when the arc suddenly made an extremely loud pop sound and then lost audio completely. The app wouldn’t let me adjust the volume and Alexa wake up didn’t emit its usual tone. I had to remove the power from the arc and reapply which resumed the audio. I’m concerned that one of the speakers in the arc may have been damaged when this happened. Has anyone had this issue?
We have had no issues with the arc since purchasing it earlier this year.
Hi everyone, haven’t posted for about a month because I have been trying out a bunch of different configurations with my ATV / Series X / LG C1 combo.
I originally posted about how deactivating “Dolby Vision for Gaming” on the Series X cured the pop symptom that I got while returning to the Home Screen after playing a game. This to me didn’t really make a ton of sense seeing how the audio was in a separate container than the video. But I even went so far as reactivating DV to see if I could get the pop to come back and sure enough within a day it did.
Then I started playing with the CEC settings. I found that on the Xbox if I completely deactivated CEC and rebooted all my hardware I didn’t get a pop regardless if I had Dolby Vision active or not. It also explains why I don’t have the issue on my ATV as I have the device control set to off. I have been pop free for over a month. Full disclosure, there was a LG firmware update for the TV during this time, so there is always the chance that a bug fix from the TV was the true remedy.
It’s very plausible that Bad CEC handshakes could be the explanation why some users are now getting the pop on the PS5 which I found surprising as it doesn’t even use the Dolby MAT container. Also could explain why some users say as soon as they got one pop….they get many pops as maybe their TV hasn’t gone through a full power cycle reboot and are still using a problem handshake.
For the user community, maybe try to deactivate device control (CEC) on their device and fully unplug all their hardware, see if they get the pop anymore.
You know, I can’t help but think that if it’s a known issue, ethically, Sonos should put a warning on the product page. Or maybe mention the malfunction in an FAQ.
Right now we keep having new customers that have to go through all these steps to figure out what’s even going wrong.
Hi
I get the pop on Xbox at 4K60. I always use 4K60 because Sony fibbed about 4K120 support on the 900H TV. It actually displays 4K120 input at 3840x1080, making fine elements such as text and icons blurry. At 4K60 you get full UHD resolution however.

I...I think this may be it. I mean, I don't want to jinx it, but I just listened to 3 hours of Atmos content on my Apple TV without any pop. I've never been able to go a full episode before. Dolby Vision and Atmos both, only disabled CEC on Apple TV. Not super ideal but volume control works just not turning TV on and off. If nothing else it points in a direction to look. Please don't make me regret this post.
I have performed the following testing:
It is possible that somewhere in there we are looking at a permanent fix. At this point, I consider it more likely that we have a reset to “before the first pop”. I had Atmos for weeks before it popped for the first time. If CEC ties into the Arc malfunction, it also raises the question why only LPCM/Dolby MAT Atmos is affected.
When I have time I will continue testing by reconnecting the Xbox and playing with its CEC settings.

I ONLY turned off CEC while leaving Volume control on through HDMI (not sure exactly how that works without CEC? unless its a new eARC feature?). I was able to go 3 hours without a pop last night. Never before has that been possible with my Apple TV. I will keep testing with this setup and see if/how long for a pop.
Further testing:
My current state is Apple TV both CEC options on, Xbox all CEC off. Atmos on both, no pops yet. If you are affected by the pop, please try the following steps:
Had this happen again today & scared the heck out of me, 4th time in as many months when I was turning off the series x, every-time this happens I feel as if it will be the one to break a speaker, so frustrating.

I’m about 30 mins in, no pops hopefully not just a premature celebration!
No XBSX but have a PS5 / ATV 4K (2022) / Arc / Sub / One SL and been popping for the last 1.5 years.
haven’t switched the CEC on on my PS5 yet

You tried the solution just above your comment? Have tried myself and hopefully has resolved the issue :)

Will do thanks for that, will update.
Another Victim here 
(from Mexico)
The first time I experienced the (super loud/explosive) pop was when I was navigating the menu of my XBox Series S. (It was soo scary BTW, I almost had a heart attack).
The first thing that crossed my mind was that my 2 days brand new Sonos Arc was dead because that pop literally sounded like something exploded inside, causing physicall damage of the speakers.
I inmediatly googled the issue and found several post here and on Reddit of people having the same issue.
I also had the problem with my Apple TV 2022 hearing weird noises/mini-pops and cuts in Apple Music when listening songs in Dolby Atmos.
Just a moment ago I was watching The Last Of Us (first episode) in HBO Max and having a lot of mini-pops (annoying but tolerable) but in the minute 22 (when we see the infected old lady) again an extremely LOUD and horrible pop happened (I swear my soul leaved my body). Even my dogs went crazy or scared or both.
I ended watching the episode in the native TV App and had no pops but the Sonos App showed only Dolby Digital 5.1 and no Atmos. BTW my TV is a Hisense U8G 65) .
As described in this post, the pop only happens whith dolby Atmos content (or in the Dobly Atmos Mode in the case of X Box Series S).
After disable Atmos in both devices the pop is gone, but of course what is the point of spending this ridicously ammount of money for a product if you can’t use it for what was designed and marketed. Truly shocking that the recommendation of the Sonos support was turning off Dolby Atmos (a key feature) 🫠
I am honestly very dissapointed of Sonos and now I regret of buying this thing because it’s celar that the company is aware of the problem and after all this time not even a formal statement or answer has been released (and not to mention a fix for the issue). For what I see the users are the ones who are making an effort to try to solve this or at least know the cause of the problem.
I will surely going to end returning tIhe Arc to Amazon before it Kills me of a scare.

Quick update, I got the replacement Beam on Friday and so far so good. No pops at all as of yet.

Did you fully reboot your TV and devices after disabling CEC? This is important as CEC settings seem to hang around as the TV never acutally gets turned off….it only turns off the screen

Just so I’m clear, CEC was disabled on the Apple TV 4K and Xbox Series X (the two devices that I’m affected by) as well as the TV? A lot of tests say 3 hours, which is a decent amount of time, but has anyone tested for a longer period of time? While disabling Atmos in both devices is annoying, I haven’t really missed it as I’ve been watching my Atmos content directly from webOS and it really hasn’t affected me in any meaningful way!
I only disabled CEC on my Xbox, which is where I initially heard the pop. No issues as of yet and it’s been about a month. I didn’t disable CEC on my Apple TV and so far, including Last of Us, no pops.
No pop in the last four days, including both Apple TV and Xbox usage. It sucks not having Xbox CEC (used to be that I didn’t need the TV remote at all), but it’s a price I’m willing to pay and I don’t want to risk the pop coming back after the bad times over the last two years. I’m really hoping that Sonos is paying attention and eventually giving everybody an official statement on the cause and resolution of the pop.

Does it matter if I unplug the TV from behind the TV vs unplugging it at the wall receptacle? It seems like I loose certain TV settings and Bravia Sync settings when unplugging from the back of the TV. I may be loosing my mind but it seems different. Thanks as always.
It does not. Unplugging is unplugging. That’s a purely physical layer move.

When you say ‘unplugged everything’ does that include the HDMI cables and if so, any particular order when plugging everything back in? HDMI then Power? Or Power then HDMI? Thanks everyone for the testing and tips!
