Dolby Atmos causing audio on Arc to "pop" then cuts out

Sounds like the XBox is generating this scary pop for some reason….Sonos is just playing what is sent down the wire. 

Maybe, but before my arc, I have a Beam, and never this issue with my Xbox.

The Beam, assuming it was Gen 1, wouldn’t have been receiving an Atmos signal. 

Yes, my BEAM was gen1

Posted on the other thread but will share my insights here as well.  I too am experiencing the issue on both XSX and ATV4K, more often on the series x opposed to the ATV4K but it aligns with everybody is saying

i just finished a RMA process because I caught the pop on video and the support rep processed it as a hardware failure, and the new arc and hdmi cable behaved well for the first three weeks until tonight.  Always happens in the same spot on the series X, when I’m going back to the Home Screen after playing a Dolby Atmos (MAT) title.  
 

So far I have tried 2 ARCs, 3 Certified HDMI 2.1 cables, two different devices (Xbox and ATV) and two different TVs (Sony x900h, LG C1) and with the pop happening on all combinations, the common theme is the Dolby Atmos MAT format.  I too have not seen the issue on any other audio format or TV smart app

Also opened a ticket with Microsoft, to see if there is something on their end they aren’t doing correctly

As for Sonos, there are literally a 100 users over this thread and the one I’ve posted to “Sonos arc pop then Audio Loss” describing the same issue.  I find it hard to believe Sonos can’t reproduce this issue when it’s so very common 

And yes, I am aware that I can use a downgraded audio format and not have this issue, but when spending $2,000 on a speaker system that does Dolby atmos.  I certainly want to take full advantage 

I’ve been having the same issue but with the Beam gen 2 playing Atmos content from Apple TV 4K.  Apple even replaced my Apple TV unit with a new one, but issue didn’t resolve.  I had seen that TV OS 16 had fixed similar issues in beta, but after finally getting the OS 16 problem still occurs.  Any fixes lately?  Where is Sonos support in all this? 

I’m just here to add my voice to the crowd.  Sony KD-43X85J. Apple TV 4K. Sonos Arc.  Loud pop in first 5-10 minutes of Atmos content.  If I unplug the arc and plug it back in sound comes back and no more pops for the rest of the evening.  TV Apps play atmos content fine.  Serious first world problems here… but I’ve spent first world prices on these products.

One thing I read on another blog post which I’ve been able to confirm, is this only occurs when playing Dolby Vision and Dolby Atmos at the same time on an Apple TV.

When I disable Dolby Vision, and use HDR 60Hz on Apple TV with Dolby Atmos enabled, the popping noise loss does not occur. When I turn Dolby vision back on, pop and noise loss within 10 min. Note only happens with Dolby Vision and Dolby Atmos content. 
 

Sony X900H

What started the issue was Xbox Series X. I never had this issue using Sonos with my Apple TV 4K with Dolby Vision and Dolby Atmos both on for almost a year. Then once I got an Xbox Series X last week, it popped with Dolby Vision and Dolby Atmos on the Xbox Series X enabled.

After this occurred with the Xbox Series X, Apple TV 4K started having issues immediately. Prior to Xbox Series X, zero issues with Apple TV 4K at any setting.

I tried changing out HDMI 2.1 cables, 8K 60Hz and 4K 120Hz. Not a cable issue. It only occurs when Dolby Vision and Dolby Atmos is enabled. After the error occurs.

I sincerely hope Sonos addresses this. As it’s been a year now from all the complaints and still no resolution much less recent responses that provide an actual fix.

Wanted to post an update here since it’s been a while. I’ve been “pop free” for over a month now.  All I had to do was disable eArc on my Sony television.  I have the Arc, with 2 One SLs, and a sub.  Television is Sony X900H.  I can confirm that once I disabled eArc I was able to run Dolby Vision and Atmos content through the Apple TV with no popping.

Please go to the post “Sonos Arc loud pop then audio loss” and add you story/experince there. So we have everything at one place. Sonos needs to fix this.,
