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.

Wait. If using the HDFury Arcana fixes the issue, doesn’t that mean the issue isn’t in the Sonos, but in the TV itself?

I doubt it. The thread has people with all brands of TVs having the issue. Also, most people have their TV set to passthrough, so the TV shouldn’t really be doing anything (as I understand it at least).

Heh, I hear you, but ‘should be’ and ‘are’ are wildly different. And if using the Arcana ‘fixes’ the issue, it sure seems to me to point the finger upstream from Sonos. What that does is effectively remove the TV set ( and the CEC computer in it) out of the equation.

Just because some upstream devices don’t trigger the Sonos Pop in no way implies that the bug isn’t in the Arc/Beam 2. Two facts point strongly, to the edge of conclusivity, to Sonos:

  1. The vast heterogeneity of source devices triggering the Sonos Pop. Xbox and Apple TV passing through LG, Sony, and Samsung TVs. Some Samsung TVs even with native apps. The counterfactual hypothesis is that all of these makes are bugged while Sonos is blameless.
  2. Switching to any other brand soundbar eliminates the pop.

Considering that @Airgetlam and @Ken_Griffiths have never been affected by the pop, yet they spend extensive time in any thread discussing it trying to divert from Sonos, my hypothesis is that we are looking at an undeclared conflict of interest.

Please let me know how to get Sonos to pay me. I could use some additional income, or even product, instead of merely the satisfaction I derive from attempting to help my fellow humans, obviously a bad instinct that Ken and I share.

In my experience, once one starts starts with the ad hominem accusations of others of being shills, they’ve lost the argument.  Shills or not, if you cannot dispute the facts, then you cannot dispute the facts.

I also find it highly ironic that in the same threads where people are asking for “official” updates or statements from verified Sonos personnel, others are vilified for being “shills” with absolutely no proof they are working for Sonos.

If you say you don’t have a conflict, I will take you by your word.

I have tried, unsuccessfully, to apply to work at Sonos. I am a user, just like everyone else. All Sonos employees are required to identify themselves as such in their avatar.

I trust your word. But just to clarify to you, I wasn’t hypothesizing something as scandalous as you being a sock puppet for a Sonos employee.

It’s just, to me, your approach comes across as trying to latch onto any evidence that this might not be a Sonos problem while simultaneously encouraging affected users to not post about it publicly and instead reach out to Sonos one-by-one.

So the impression formed for me that you may have a friend that works at a store selling Sonos systems, or works for Sonos itself, or you have been a beta tester and want to maintain that status, or a similar conflict of interest.

Obviously, I was wrong. However, I think it is possible that you come across similarly to other posters. As such I think it is great and productive that could dispel any such concerns.

@ProfessorFrag 

I’m personally retired (15 years this July) and live with my Wife (Jane) here in the U.K. (Midlands area). Our children have flown the nest long ago … I am not, nor have I ever been, employed by Sonos.

I, and several members of our family & friends, are admittedly Sonos enthusiasts and between us all, own a fair amount of different Sonos products. My own reasons for hanging around various threads here are mostly two-fold… to try to help fellow Sonos users and to also keep abreast of the current hardware and software developments.

Amongst other things, I’m also a bit of a home-network enthusiast too these days and so hang around other forums with a similar purpose in mind, that’s mostly to improve me own knowledge in this areas and to keep up-to-date with home WiFi mesh networks.

I’m not sure how to begin to convince you that that is the truth, but it is what it is🤷‍♂️ …and you’re correct when you say I’ve not had the Arc popping issue here with our Sonos Arc/Surrounds/Sub, but as mentioned many times here, I do not own an Apple TV 4K, or an XBox - so have not ever come across any ‘popping’ noise as described in this thread.

I have come across other people though, who got rid of their XBox and Apple TV 4K and replaced them with similar hardware and not had the popping issue since.

So I’m still not sure, personally speaking, that this issue is entirely down to Sonos and hopefully I am free to express that personal view in the thread here, as there is evidence in the posts that the same/similar popping noise has been encountered on other brands of Soundbar/Receiver whilst playing LPCM uncompressed Atmos audio from an Apple TV 4K and/or Xbox. 

I hope that clears up any thoughts you may have about my purpose for being part of the Sonos community here.
