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.

They have to fix this… I got in touch with customer service about this issue around 2 or 3 months ago and they recommended changing the channel of the network of the Sonos system and it seemed that it did the trick for a while (at least when I used only my Xbox), but the moment I play music with Apple Music… I start getting that loud “pop” that even makes my ears hurt for a while. Today, after a while without hearing it (mainly because I had only used my Sonos system to play sound from the TV/Xbox/PS5), I tried playing music again directly from the Apple TV and it happened again.

→ Philips OLED TV (2022 model)
→ Arc + Two ONEs (one is a ONE and the other a ONE SL) + Sub Mini (it happened also when I didn’t have the Sub Mini)
→ So far it happened both with:
· Xbox Series X (when I wasn’t playing anything and there wasn’t any sound coming from the TV, which means basically when going back to Home Screen)
· Apple TV (many times), mostly when playing music directly from the Music app (or streaming music from any iOS device to the Apple TV). It usually happens when changing from one song to the other (when there’s that brief pause between songs). Normally it doesn’t happen with Youtube/Disney+ or other video apps on the Apple TV.

· It also happened when playing some movies directly from the USB stick and the TV native player. But it did happen when the content was paused.

With more than 1500€ spent on this system… I find this unacceptable (especially considering that this issue goes back to 2020)

Yep, it’s been years looking at this thread. We did a video of it too.

Good that you did a video, Ovios73! Have you shared this with the Sonos team?
I mean, they must have experienced this in their tests! It’s not that hard to reproduce it…
I’m going to try to turn off CEC for all devices and see if that helps, but that isn’t obviously the solution. They need to fix this with a proper software update.

I’m starting to believe that this is very similar to an issue that the original HomePods had, where they also popped (really loud) sometimes when playing music and sometimes just a few seconds after you stopped playing content on them. Apple ended up fixing this (it took them a while...) with a software update → https://www.google.com/search?client=safari&rls=en&q=homepod+popping&ie=UTF-8&oe=UTF-8. There’s even a technical explanation of why that happened, so something similar might be happening with the Sonos speakers.

I’m reading in the YouTube replies on the video that some have had Sonos replace their Arc. Has anyone here had a replacement and did it help? How long had you owned your Arc when they agreed to replace it? I got mine very early on in it’s availability and the popping has been going on for nearly 2 years.

I’d like to know too because this has to be fixed soon. I don’t care if they have to replace it or release a software update. Enough is enough. 
 

im about to stop recommending Sonos to clients, which is quite often, if they don’t give us an update soon.

@KrylonBlue thats right ! I have enough of this *** . They kept on ignoring this issue. Telling us the engineers are working on the fix , for two years !!!! How many damn cars have already completed production in two years ?! This is such a simple fix by software , I’m going to call CS on Monday and demand my refund on my ARC that was purchased back in 2020 !

Did not help for me, they sent me a replacement arc and I still had/have the problem.

Another update for everyone.  I was struggling with pops again with my series x as I couldn’t seem to get consistent CEC control when going back to the main screen

i went back to what was working before for me, and that was disabling Dolby vision and Auto HDR and I have been pop free since then.  Full disclosure though, I didn’t have a pop when I was playing cloud gaming on my Xbox, but since the cloud controls those settings, I just decided not to use it at all

If I had to guess, it’s still has to do with HDMI settings renegotiation upon settings change.  As to why removing Dolby vision or auto HDR from the occasion fixes it…I’m not sure, maybe less things to negotiate?

I do agree with the forum though,  the silence from Sonos only makes it worse.  Step up and make an official statement to at least let your user base know where they stand.  Enough is enough

Turning off Auto HDR on series X does make the pop go away . I’m happy now at least I can play Resident evil 4 with Atmos !! :)
