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.

Check the Audio settings in the AppleTV 4K box. Make it’s set to Auto Dolby Atmos available. I believe that’s the setting… I’m not at so I can’t verify the the exact wording the setting.

Yes, Dolby Atmos is enabled on the AppleTV Settings. When I turn Atmos off in the ATV settings I don’t have the issue at all. It only happens when Atmos is enabled and playing. I’ve verified each time its only in Atmos that causes the issue by checking in the Sonos app and Atmos was shown as playing.

OK…so check the HDMI cable for the ATV, make sure it’s running the latest TVOS and/or reset the ATV if necessary.

Got it. I know I’m running the latest TVOS. I’ll check the cable and possibly reset the Apple TV and report back later this afternoon.

After checking the cables and resetting the Apple TV I am still running into the same issue.

Honestly, it sounds (sorry, pun not intended) like a switching problem in the TV set itself, not in the Apple TV or Sonos. The Sonos would be playing whatever is sent down the line from the TV. I’d be double checking for updates of the TV’s OS.

Can you play Atmos content directly from the TV through Netflix and see if you still have the same issue. Need to rule out the TV or Apple device first.

I’ll play some content tonight from the TV itself and see if Atmos is steady. It not extremely frequent so reproducing the issue will take some content watching. I’ll report back with my findings.

After playing content over both Apple TV and the build in TV apps it looks like its the Apple TV that is causing the issue. I had no audio cut outs yesterday. 

With that, does anyone know of any settings to get Atmos to consistently work over ATV?

Assuming the TV is set to passthrough, earc enabled and plugged into the correct port from the Apple TV device it should be fine. Did you say you've tried a factory reset of the apple device ?
