Sonos Arc loud pop then audio loss

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!

Good news! We are pleased to share that our team has identified a fix for the popping sound on Arc and it will be shipped to all customers as part of a software release today, Thursday Nov 16 at 09:30 ET, 14:30 GMT, 15:30 CET. Please note that some app stores may take an extra hour or two for it to become available.

During our investigation we uncovered a rare bug that impacts how Sonos Arc and Beam (Gen 2) in certain home theater configurations process Dolby MAT, a streaming technology which is used to deliver Dolby Atmos audio over HDMI. Occasionally a Sonos product will receive a corrupted audio segment from an external source and needs to filter out unwanted audio data. The bug we identified was allowing our Dolby decoder to play audible errors on certain home theater setups rather than concealing them. The solution we’ve built and tested improves our Dolby decoder so it better filters out corrupt audio data that can manifest as a popping sound. We’ll continue to monitor customer feedback closely after the fix has been released and ship additional updates if necessary.

We strive to deliver the best listening experience possible and work to address major issues that impact our customers. We apologize for the disruption this bug has caused and want to thank you for your patience while our team developed a fix.

We would also like to thank our community users for their detailed setup information and steps to reproduce the issue, which were helpful to us in uncovering the cause of the bug.

Side note, anyone else find it frustrating that mods are clearly looking at this thread and taking the time to do things like manually blur out case numbers in screenshots and censor naughty words but they’ve basically gone radio silent otherwise?

Like, look at the beginning of the thread and we have responses from @Corry P on every page and now?  It’s been like two months since we’ve gotten a response.

In light of the articles that have come out it sure would be nice to know if Sonos has anything to say to us, the customers affected by the issue.

Two different missions. One is to protect us users from the vagaries of posting inappropriate data online so that it might be used against us in some way, the other is being a spokesman for an entire company.

Happened to me as well on my Arc. It is reproducible for me. When I run steam in Big Picture mode and start a game, it pops.

Any luck with the new Sonos update today? 

If @Paul Tsang ‘s conversation with support is anything to go off of, it’s probably going to be a few more patch cycles before we can expect to really see anything at all.

For what it’s worth, current notes are just “bug fixes and enhancements”.

Really glad someone brought this to light...I had no idea about the issue until recently and I have a Sonos Arc on my wishlist for the house we’re building (I’m still game if they issue a fix). Good luck to you all, hope they release a fix soon!!

My Decade-Long Advocacy for Sonos Comes to an End…

I’ve been a Sonos advocate since 2010, a relationship that lasted longer than most Hollywood marriages. Over the years, I've filled nearly every room in my home with Sonos speakers, singing the brand's praises to friends and family who then also took the plunge into this wireless speaker ecosystem. My faith was so unwavering that I even invested in Sonos by purchasing a significant number of shares in the company. But, much like any relationship that ends bitterly, my story with Sonos has reached an unfortunate climax.


In 2021, I decided to up the ante by converting my home cinema into a Sonos sanctuary. My set-up included a Sonos Arc, Ones, and not one but two Subs. The vision was cinematic audio bliss. However, the reality has been far from it.


For the last two years, my movie-watching experience has been marred by an incessant, loud popping sound emanating from the Sonos system. To put it mildly, it's been a pain. It’s like having an uninvited guest in your home that not only interrupts your movie but yells in your ear while doing so. 


What adds salt to the wound is the customer support experience. I contacted Sonos support three times, hoping for a resolution. Each time, I was met with the blame being shifted onto my TV or some other random piece of equipment. Following their suggestions, I replaced my TV and even my Apple TV, but to no avail. 


The only “solution” has been to disable CEC and Atmos features—two of the main reasons I invested in the system in the first place. This is the equivalent of buying a sports car only to find out it can’t go above 30 mph.


I reached out to Sonos one last time, asking for either a replacement or a refund. As you might have guessed, both requests were met with a hard no. At this point, it became clear: Sonos had their chances and they've lost a once-devoted advocate.

So, I’ve made a painful decision. I’m selling all my Sonos equipment and even offloading my shares in the company. My decade-long advocacy for Sonos has come to an abrupt and disappointing end. As I transition to another system, one thing remains crystal clear: no brand, no matter how much nostalgia or trust it has built up, can rest on its laurels indefinitely. Sometimes, you just have to know when to move on.

I understand where you’re coming from. I really want to upgrade my rears from Sonos One to Era 300.

But if Sonos won’t even put a disclaimer or FAQ on the Arc so that buyers can know about the potential problem with Dolby MAT sources, how can I trust them to buy more equipment?

Product mistakes happen. However, when I’ve had an affected Apple product (widespread MacBook mainboard problem back in the day) or Microsoft product (red ring of death), there was public communication and they offered repair or replacement programs to make it right. That’s part of the reason I continue to buy Apple and Microsoft hardware.
