The same thing is happening to me.  

i have a similar set up.   AppleTV 4K connected to Q90r sound bar HDMI1. And sound bar connected to Samsung tv q80 via HDMI arc.  

I fiddled with all the Apple TV settings.  changed the HDMI cables.  

Funny thing is Disney+ app doesn't do this and it uses atoms as well which leads me to believe it's Netflix app

Hi

I only have Apple TV (older version) and used it purely to stream music thru airplay (tried on HDMI1/2). I did facing dropping issue with the music/screen - however, i recently changed to different HDMI cable and the issue seems like gone. Perhaps you can get a different HDMI cable and give it a try... or you can use the supplied samsung HDMI cable (with ethernet) and connect from your apple 4K to the HDMI. Just try out if the sound is dropping or not.

I have changed the HDMI cable.   This happens whether the content on Netflix is atmos or 5.1.   

I was fiddling with sound settings yesterday - and rebooted and rebooted.  Nothing 

I reset the HDMI connection within the atv4k settings for video and that seemed to help.  For the rest of the episodes it was fine.  

why it only affected Netflix app is beyond me

Can you try turn off the HDMI-CEC feature on the TV and try again? Different brand might have different naming for the feature for example Sony is Bravia Sync.. I saw a lot of people solved their HDMI handshaking issue after turn off the CEC.

do you get dolby vision to passthrough through the soundbar from your Apple TV?

I don't know to be honest.   The TV is a Samsung q80.   It's so crisp and clear in comparison to the 10 year old LG plasma I replaced - I don't know how I would identify the difference.

you can check the source information by pressing the info button on your tv remote control. its usually labelled "info" or sometimes just a stylized "i". This will display all source signal information such as resolution, frame rate and HDR status. If you are getting Dolby Vision HDR it will be shown there.
