Sonos Arc + AppleTV + Samsung TV = No Dolby Atmos

My tv is a Samsung QN85QN90AAFXZA. It’s less than a year old and has eArc.
Hooked up the Arc and 4K AppleTV but don’t get Dolby Atmos showing during playback in the Sonos app… It reads “Multichannel PCM 5.1”

Known issue? User error?

Any help would be greatly appreciated

Thanks!

How old is the Apple TV? It needs to be one of the newer ones to support Atmos/ Dolby Digital Plus. Might be worth double checking that your Apple TV supports these formats, especially if that isn’t appearing as an option in the settings. It is running tvOS 16.0 (20J373)?

That’s generated by the TV, not by Sonos. While I think it’s unlikely, you may want to poke around in the TV’s settings for something that may affect that.

I’ll take a look.
Oddly before the Sonos I had a Samsung soundbar hooked up the same way to the tv but no on screen indicator

Odd indeed. All Sonos does is pass a “I’ve adjusted the volume based on your instructions” back to the TV set, the TV set decides what to display. There just isn’t the ability for Sonos to put that on a screen. Or choose to display or not display it.

Bruce - Thanks so much for all your help and expertise on these issues!

You’re correct in that I don’t find anything in the TVs menu looks like it would turn off the overlay.

Not that I’ve owned a lot of TVs, but the implementation of the CEC/ARC standards are mostly similar. There are small variations, which can cause issues (like the Samsung Frame, for instance), but I’ve not yet seen one that allows that sort of control. Doesn’t mean there isn’t one, just that I’ve not yet seen it :)

So… my Samsung TV is arc, not earc. How can I get Atmos sound from my Appletv 4k to play through my Sonos Arc? I see the option on the tv for Dolby Digital+ but it is greyed out. Thanks!
