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.

I got my first scary pop last night at about 12:30 am. Scared the heck out of me. Thought something exploded. I was using my Xbox Series X connected to my LG C9 with EARC HDMI connection to Sonos Arc.

I recently switched the HDMI input on my C9 that the Xbox Series X is using to PC Mode to unlock 4:4:4 full bandwidth signal. Not entirely sure it was related, but was an interesting coincidence. 


Also had my first reoccurrence of this issue last night with a Series X and Sonos Arc with a Sony x900h TV

 

I was watching videos from the Dolby App and as soon as I prematurely closed a video by pressing the back key I got the pop sound, Arc stopped working at that point until reset 

 

Worth noting that the surrounds were still working fine afterwards only the ARC wasn’t.  
 

Obviously I don’t want to do damage to the Arc, so if it is in fact just garbage playing at highest volume I feel a little more at ease, would be nice to see a true diagnosis and a fix though


I have the same problem. 
It happened to me twice, for the moment, while watching a movie  on my AppleTV. 
 

diagnostic : 878538476


Just happened to me. LG G1 and Series X. Just in the middle of playing Psyconaughts 2 and then loud bang followed by no sound. Switching input brought the sound back. Scary. 


Did you submit a diagnostic, and contact Sonos directly?


I have been having this issue too. Happens a couple of times a week, both on Apple TV 4K and Xbox One Series X. Very annoying. Downright embarrassing when guests are over. 
 

It’s so loud, the first time I thought a big piece of furniture had fallen over somewhere. 


I too am experiencing this issue.  There’s a loud pop / bang noise and then the Sonos Arc stops outputting sound.  I have to switch sources and back for it to work again.  Really troubling and I fear something is wrong with the hardware.  I bought this earlier this year.  Has the cause been identified yet?

EDIT: I notice it happens a lot when I start playing on my Xbox Series X.  Also got an Apple TV 4K and sometimes it’s happened there as well I think.

It sounds very much like a gunshot - very loud.  I just read some of the feedback on this thread about taking a video recording - I find that to be very unhelpful since how am I supposed to know when this will happen? It appears to be quite random!


Then submit a diagnostic within ten minutes of the occurrence and contact Sonos directly with the number of that diagnostic. If the cause is the Arc, it should show up as an issue in the diagnostic. Sonos then would have the opportunity to not only understand what the issue is, but hopefully be able to assist you in fixing the issue. Anecdotal discussion provides no hard data for them to confirm anything.

As an alternate viewpoint, this does not ever happen on either of the two Sonos Arc devices I have, which suggests, from a logical perspective, one of two things. Either the signal is being sent by the TV to the Arc across HDMI ARC, or there is some failure in your particular Arc, neither of which can be traced by mere text discussion. The diagnostic, presented to Sonos and discussed would be the optimum course of action.

Hi I also have the same issue - please advise how do I send you the diagnostic data? What do I need to do? Thanks!


Fair enough, let me supply a link to the FAQ: submit a system diagnostic


Oh, and after submitting, you should call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.


It’s probably too late for my specific case since I already restarted the Arc to get sound back, but I went ahead and submitted one now. 1617994945
 

I disagree that contacting support one by one is the way to go though. We would never know that the problem is widespread if we did that. And what has been posted here as results from support (“Send us video proof. It’s your specific sources that are causing the problem. Etc.”), I would refer to as the run around. I honestly do not have time to try and record this issue. 
 

I’ll wait until we hear in this thread about what the issue is, or what Sonos is doing to resolve it, before I reach out to support. 


Just had this problem with my new Beam Gen 2 and Xbox Series X. Never happened before with my Beam Gen 1.


Hi  I’ve just had the same problem I  was watching YouTube on Xbox series x and the arc popped like something had blown then no sound changed over to sky and sound came back then about twenty minutes later it did it again while watching YouTube on Xbox series x it’s seems ok now but do you know what’s causing this as this thread been going for sometime now without any solution 


It just happened again and I managed to grab a diagnostic immediately after: 2061452815
 

Just in case this helps with Sonos acknowledging the problem as systemic rather than individual. 


Same issue here. Loud Pop and silence until cycling power to the ARC. Happened twice when streaking on Apple TV and I’ve only had the Arc for a month or so. I submitted a diagnostic but was told by the technician that is was unusable because  they can only see it when submitted when watching something directly on the tv because that is what the ARC is connected to. I’m on an LG 65 CX TV. The agent told me everything looked fine but to change settings on the tv from auto to PCM. Hopefully that helps


Definitely seems like of Sonos dedicated a little time and money to endurance testing in some of the configurations listed in this form, that they could provide an answer to their customers. Not impressed that’s this form has been going on so long with no answer


Last Update: After setting to PCM I noticed a drop in sound quality so I did a little digging. On the LG CX I have enabled eARC and set the option between PCM, Auto, and pass through to pass through, it was previously set to Auto. Hoping this resolves the popping issue. Really hoping PCM isn’t the solution because I think it’s a noticeable degradation. 


OK, sorry a lot to unpack.  Same thing happened to me with Apple TV on a Vizio OLED 65 inch.  Who do I call or what do I do.  My diagnostic was sent my confirmation is 1189733447.  This is a fairly expensive item to have this happen,  I have noticed I am limited to how load I can set the arc now before it goes down in volume and a orange light appears.  Also sound quality has taken a dive for sure.  Didn’t know if that has also been happening.  

 


First post - and it’s on this thread because this happened to me tonight for the first time (and it did it three times).

Had the Arc since mid-August with no issues through any source but tonight watching a film on Apple TV (in Dolby Vision and Atmos) had the loud pop a couple of minutes in and then only surround speakers working. Went through setup again and all was fine until it did it again (twice).

Found this thread so I did a power cycle and it ran for over an hour without a problem. I’ve had no issues with other Atmos or Dolby Vision sources and it had been faultless up to this point.

Next time it does it I’ll capture a diagnostic…

 

 


Really starting to get frustrated by this problem, and based on the other users here it seems to be a little more widespread then just random individuals.  Would really appreciate a statement from Sonos on what they are doing for this problem

 

Reason why i say this is because i have experienced this issue a few times over the last couple of weeks and have submitted diagnostics for each of them

Most recent ones are: 1118141455 and 1729108796

Each time i call in the only suggestions that i get are things like power cycling and software reset….none of these obviously have solved the problem

 

For a high end audio product, i would expect a little more than silence on the support side

 

Rant over


I’ve had the same problem when using my Series X outputting Dolby Atmos to the Arc. Really loud pop which did sound like a gun shot. This was a couple of months ago. I read somewhere to disable Atmos from the Series X and Ive had no problems since, however sort of defeats the object of having an Atmos soundbar. Was just having a look around the net today to see if the problem has been acknowledged by Sonos or has been fixed. 


I am having the same issues, Sony TV and Xbox Series X connected to the eARC port on the TV.  While using the Xbox I get a loud pop, like a gunshot, from the Arc and no sound.  I have to change sound source to TV and then back to the Arc to get sound back.  So far this only happens when using the Xbox.  I have been able to watch cable and stream from the TV with no issues.


Following on from my last post- it just happened again playing Dolby Atmos from the Disney+ app on a 4K Apple TV.

Submitted a diagnostic - 1763217727

Haven’t spoken to anyone in support as it's out of hours but I’ll try to get hold of someone next week.


I experienced this same issue last night.

Loud “POP” and sudden loss of sound from Arc. Sub and rear speakers functioned normally. 

After unplugging the power, and replugging, the Arc function normally again.

Was watching Netflix on the Xbox Series X with Dolby Atmos. Arc + Sub + SR + SL.

Diagnostic reference number #67513007.

This seems to be a disturbingly common problem with this configuration.
