Sonos Arc loud pop then audio loss

I have had the loud pop happen twice today, in fact it’s been happening regularly (weekly) since I purchased the Sonos Arc nearly a year ago, my setup is LG55CX, Xbox Series X, PS5, Sky tv, Panasonic 820, Sonos Arc with Symfonisk gen 1 Lamps and I have a Sonos sub arriving in the nxt few hours. I’m worried about ruining my new sub, I havnt contacted Sonos about this as there’s no point after reading this thread that started a year ago…… it’s very poor customer service that there’s zero acknowledgement really, surely Sonos should of put out a statement by now with some information as they must of looked into it. It’s absolute crazyness when I think of it considering the price of the product and all the money spent by people in this blog from over a year back. Come on Sonos. Speak !!

@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.

And the common denominator between Xbox and Apple TV 4K (and Roku it seems), is that they all use Dolby MAT as the audio container.

The popping is really upsetting… looking forward to a fix soon!

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. 

Same issue here.

always on Xbox series x

my diagnostic code is 137046043

this happens 2-3 times a month.

Rebooted the Arc yesterday.

Made it 24 hours, a grand total of 2 shows before happening 30 seconds into an episode of Severance.

At this point, I'm ready to throw the Apple TV out of the window. It’s the only thing causing me grief. 

Having the exact same issue. Loud pop sound and then the sound turns off. Changed to TV speakers and back to ARC. Solved the issue for a while. Always seems to be happening when playing Dolby Atmos and when there is a lot of different sounds. Like the sound processor can’t handle all the bandwidth and just crashes. 

Hello, I am experiencing the same issue on an Apple TV. The issue gets fixed by rewinding the TV program or movie a few seconds, but it happens again within 10 or 15 minutes. 
 

Called in today because I experienced the issue for the first time in weeks.  Didn’t get very far with Sonos support because they wanted me to record the issue happening, which tells me they either don’t understand the issue or they can’t reproduce it themselves.  I find it extremely hard to believe that Sonos has not been able to reproduce this in the almost 2 years that this issue has been prevalent.  

Has anybody been able to get farther with support like an actual diagnosis on what could be happening here?  This is extremely frustrating for what is supposed to be a high end audio product
