Sonos Arc and 2020 Samsung Frame Atmos issue

I just bought a 2020 Samsung Frame and Sonos Arc and I wanted to test the Dolby Atmos feature but when I tried the only app I could get to output Dolby Atmos as shown in the Sonos app was Amazon Prime Video. I’m using the built in apps on the Frame TV. When I play Netflix content that should be Atmos is says Dolby Multichannel PCM 2.0. I have the premium Netflix subscriptions and it says Atmos under the title in Netflix but only Dolby Multichannel PCM 2.0 in the Sonos app. When I play from Disney Plus I get Dolby Multichannel PCM 5.1 at least, and I get Dolby Digital Plus 5.1 when playing Apple TV+. I understand their might be some issues with Disney and Apple, but at the very least Netflix should be outputting Atmos. I’ve also read about all the issues with eArc and audio cutting out with the Samsung Frame, fortunately I haven’t had any of those issues, just the issue of it not outputting Atmos when it should be. Hopefully I’m just missing something simple.

Can you post your current audio and HDMI settings on your TV?

What other options do you have under “Digital output audio format”? Is there a Pass Through setting?

The sound output now automatically changed to: Receiver (HDMI-eArc).

Yes other options for Digital output audio format are pass-through and PCM. But it doesn’t let me choose pass through, it’s greyed out.

If I change HDMI-eArc Mode to off it changes to Dolby Digital plus 5.1 in the Sonos app when playing Netflix instead of Dolby multichannel pcm 2.0, but never Dolby Atmos.

The goal is to get the pass-through setting activated. With it set to Auto, the TV seems to be converting the audio it receives from the apps to PCM.

Hmmm It lets me change it to pass through if I’m watching normal cable but whenever I switch to Netflix it goes back to auto and pass through is greyed out.

Switching from auto to passthrough while watching cable also switches the audio in the Sonos app from Dolby multichannel pcm 5.1 to Dolby Digital plus 5.1

Dolby Digital Plus 5.1 is what you want from cable. The “passthrough” setting is allowing the audio to pass through your TV to the Arc in its original form which is what you want. Now we need to figure out how to achieve the same with your TV’s internal apps.

Well that’s good. Ya the main issue seems to be the TVs internal Netflix/Disney/Apple apps, specifically Netflix. It’s weird that amazon prime works perfectly but nothing else.
