Hi everyone,

Just installed my new ARC sound bar.

My setup is Samsung TV with e-ARC, Apple TV 4K last generation.

My TV is set to (HDMI-eARC Auto)

Apple TV is set to “Change Format - No"

When playing a Dolby Atmos movie on Netflix from Apple TV, I get Dolby Atoms signal on my Sonos App.

When playing a Dobly Digital movie on Netflix from Apple TV, I get PCM Stereo.

I couldn't find how to get Dolby Digital signal in Sonos App…

Appart from Dolby Atmos, all other contents are playing in PCM Stereo. 

Thanks for you help guys.

Set the Digital Output Audio Format setting on the TV to Pass-Through. With this setting, all non-Atmos 5.1 sources should play as “Multichannel PCM” from the Apple TV.


Thanks so much 👍👍

Works fine now
