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

I purchased a Sony KD85X91J in July equipped with eARC so I could listen to content from my Apple TV 4K in Dolby Atmos. The problem I have is whenever I play Atmos content (and ONLY Atmos content). Every so often the Arc has a quick popping sound followed by the Arc losing audio until I back out of the Atmos content I was watching. When I back out I can start the content again in Atmos and it will work for a while until the pop and audio cut out happens again. 

I have a 5.1 setup with the Arc, 2 One SL’s and a Gen 3 sub. The bass and surrounds still play audio after the cut out. Only the Arc is affected. 

The HDMI cables i am using are both rated to handle Atmos content. Link to the cables being used is below.

Is there a fix for this issue? It’s very frustrating investing into a system that cannot deliver what it advertises and I’m hoping theres something I’m missing that will easily solve the issue.

I reset the Apple TV again it applied an update that it didn’t do in the last reset. It seems (right now) that the Apple TV is playing the Atmos content fine. It happens intermittently so I’ll report back of the issue happens again.

    Reporting back. This issue happened again. It only happens with the Apple TV 4K. I’ve been watching Atmos content through the TV apps and its worked perfectly. Not sure what the issue is with the ATV and its a little annoying to switch back and fourth but at least I’m getting the full benefit of the Arc now. 

    If anyone has had the same issue and they’ve fixed it please let me know.

    I experienced this very issue last night – nearly soiled myself thinking that I’d blown a driver.

    Sonos Arc (with 2 One surrounds and a 2nd gen sub) connected to an Apple TV 4K (2nd gen) and a Sony XH92 – config not changed in over a year since purchasing last November.

    Watching Shang-Chi on Disney+ via the Apple TV, no less than 4 interruptions. Fixed by backing out and entering again, or disabling Atmos entirely. 
     

    I get the feeling it's an encoding problem from tvOS – this is the first Atmos movie we've watched since upgrading to tvOS 15.  We did upgrade the TV to Sony’s latest Android 10 firmware recently, but that has yet to be troubleshot. 
     

    Next steps are to try for me:

    Atmos content from Disney+ via aTV

    Atmos content from other sources via aTV

    Atmos content from Disney+ via the native TV app


    See if the issue is Atmos itself with the TV/Sonos, or the Apple TV.

    Apologies if you already mentioned it but can't find it if you did – what source were you playing from (on the Apple TV)?

    Just tried running the same movie through the Disney+ app for Android TV built into the Sony TV itself. No issues for the first hour. Happened twice until this point.

    I’ve been experiencing the exact same issue for the past month. AppleTV 4K (2nd generation), television is Sony X900H, and the Arc. When playing Atmos content I will get a loud pop then all sound cuts out. I have tried every setting imaginable and the only thing I can do is turn off Atmos content on the Apple TV.

     

    I have the Arc connected to two One SLs and the 3rd generation Sub as well.

    I’ve experienced this twice, both while watching Dolby Atmos content on Apple TV like movie rentals. Just happened again today. Loud pop, no audio from ARC until I back out and play the content again.

    LG C1 TV, eARC, passthrough

    Just to troubleshoot, what sources is everyone using? Disney+, Netflix, Apple TV+, or a mix if various?

    It seems that this issue seems common amongst Apple TV and Xbox users; seemingly with Sony and LG TV sets.

    What version of tvOS is everyone using? It seems that tvOS 15 has caused various audio issues not limited to this one…

    I’m encountering the error on all Apple TV apps the stream content with Dolby Atmos--Netflix, Disney+, Paramount+ and Apple TV+.

     

    I’m using tvOS 15.2 beta release.  I switched to getting beta updates on tvOS in the hopes that the audio issue would be resolved quicker.  It has not.

    I was thinking about going to 15.2 to see if it would fix it, sucks to hear that the issue still exists. Hard to say if it’s an Apple issue, Sonos, or a mix of both at this point. I’d imagine that would be something for Sonos engineers to figure out and fix or report.
