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 experience the issue, reproducibly, with Apple TV and Xbox. Sonos recommends to turn Atmos off when using those devices. In the main thread on this problem, we had a few others report the pop with Dolby MAT outputting TVs. Apple TV and Xbox users are the bulk however, presumably owing to the devices’ large install bases.

If you have a Blu-ray player that outputs Dolby MAT Atmos, it would be a great test case. We do not have anybody reporting the issue with a Blu-ray source yet.

How can I tell if my Panasonic UBP420 outputs MAT Atmos? Im currently giving TG Maverick a run through. So far so good with no pops.

I don’t know my way around Blu-ray players that much, but here is how I think it works. While playing the content, go into the Sonos App → About My System → Audio In:

If it shows Dolby Atmos (DD+) it’s Dolby Digital Plus.

If it shows Dolby Atmos (TrueHD) it’s Dolby TrueHD.

If it shows just Dolby Atmos it’s Dolby MAT.

After reading this thread, I’m now uncertain about purchasing a Sonos Arc!

I was planning on using it with my Apple TV 4K, but it appears this setup may be glitchy at best.

Is this still an issue with most Apple TV 4K users?  I’ve seen some “solutions” that involve turning off Dolby Atmos, but that kinda defeats a huge reason for purchasing the Sonos Arc.

The issue persists. We do not know what percentage of the Apple TV userbase is affected. For now, Sonos recommends turning Atmos off if you use Apple TV or Xbox. Everything works fine without Atmos.

The best I can tell you is to check out the main thread and then decide for yourself.

    Thanks. Unless this is only happening to a small percentage of Sonos Arc users, I’m (for now) not going to invest $800 in a soundbar that doesn’t support the Apple TV 4K box.

    Just remember, this does not seem to be isolated to SONOS users.

      If I had known of this issue and read this thread prior to purchasing Sonos, I would have never purchased Sonos. Especially after reading what Sonos customer service is telling their customers.

        As was previously stated by ProfessorFrag and myself and so many others on this thread, every single “evidence” that our SPECIFIC POP no audio issue IS Isolated to SONOS.  Why are people on this thread who seem to either be employees of Sonos, or somehow affiliated, trying to convince people who have paid a premium price for a defective product, that Sonos is not the problem. What is your purpose? 
         

        You even agreed our specific Sonos Arc issue is NOT the same as the Dolby Atmos crackling sound issue. So to anyone reading. Just remember this IS an isolated Sonos product issue. And please read the entire thread, before you post. All of these supposedly “helpful” opinions of how Sonos isn’t responsible for issues we’re dealing with. 
         

        Do you even know what this thread is for?

          I agree completely!  Surely SOMEONE at either Apple or Sonos knows the root cause of this?
