This is a weird one. I have had an ARC for 2 years and it has been brilliant.

Following a recent software update I noticed the sound on Netflix had changed. I checked the  Sonos App and it says movies like 6 Underground are now playing with “Dolby PCM Multichannel 2.0”.

Nothing else has changed. The Netflix App is on my Samsung TV and it recognizes Dolby Atmos is available for 6 Underground. Disney+ and Apple TV are both outputting Dolby Atmos, it is only Netflix that is having the issue. 

I have restarted everything and checked all the settings. When I play the Dolby Atmos title in Netflix, the Sonos App displays “Dolby PCM Multichannel 5.1” for a fraction of a second and then falls back to “Dolby PCM Multichannel 2.0”.
Has anybody else noticed this problem?

Log in to your Netflix account on a web browser and go to your account profile settings. Under Playback Settings, set Data usage per screen to HIGH. Also be sure to play the original language audio track.

Hi GuitarSuperstar,

Thank you for the swift response. I haven’t changed my Netflix settings for years! The Data Usage has always been set to “Auto”. I tried “HIGH” but I still have the same issue.

I checked the connectivity from the TV in case it was a bandwidth issue but my connection speed to the Netflix server is 142.7 Mbps.

The really confusing thing is Disney+, which is an App on the same TV, is working perfectly. I get the following:

Netflix - App on the TV - Dolby PCM Multichannel 2.0

Disney+ - App on the TV - Dolby Atmos

Apple TV+ - App on my Apple TV 4K - Dolby Atmos

XBox Series X - Dolby Atmos

Everything is fully up to date with the latest patches. The set up and configuration has not changed for 18 months. The Netflix App is identifying the Atmos titles as Dolby Atmos capable? If I turn that support off on the TV the Dolby Atmos logo disappears from the Netflix titles. So the Netflix App is aware Dolby Atmos is available.

It makes absolutely no sense at all.

Latest update…

I installed Netflix on my Apple TV and I now have Dolby Atmos on my Arc. Not sure how to log a case with Netflix, but their latest update has killed Atmos on the Samsung TV version of the App.

This is the first time I have had an issue with an App on my Samsung QA65Q95T…
