Greetings, I could use some help or ideas on why I cannot seem to achieve Atmos delivery. Here are the specs I am working with:

TV: A80J

AUDIO: Sonos Beam (Gen 2) w/sub and two Play:1 surrounds

MISC: Running Netflix/Disney+, etc. via the apps within GoogleTV. Also have a Sony Blu Ray Player, but this is not yet part of the equation.

PROBLEM: Films marked as Atmos on Disney+ are still playing in 5.1 according to my Sonos app. I see the Atmos icon next to/under the title of relevant content. Netflix films which are listed as being available in Atmos only list 5.1 next to the title of the film.

INFO:

-I do have a Netflix premium sub, which should provide Atmos on content that feature this Codec. -I have flipped the Sony "Netflix Calibration" to "on" -I have used the HDMI cord that delivered with the Sonos equipment, as they suggest, and this is connected via the eArc port #3 -I have tried every sound & output setting I can think of with no success. I've just restored audio settings to the factory default in hopes of achieving a better starting point.

-As far as I can tell, all apps and drivers are up-to-date, and I have done a reboot on the TV (via the remote).

-I have disabled the native TV audio and set all sound to route through the Sonos system.

I have tried to determine where my weak link might be - is it the TV, the Sonos, the Apps? Any Settings/Configuration advice from the Sonos side of the equation?

Many thanks!

Try these settings:

Speakers: Audio System

Auto System Prioritization: On

A/V Sync: On

eARC Mode: Auto

Digital Audio Out: Auto 1

Dolby Digital Plus Output: Dolby Digital Plus

Pass Through Mode: Auto

 

Also be sure that the Playback Settings under your Netflix profile is set to HIGH. Log in to your Netflix account on a web browser to access this setting.

Thanks so much, Guitar.  

I double-checked all settings and they match what you suggest.  I also set my Netflix Playback Settings to HIGH earlier today.  Double-checked and that is still what is selected.  I wasn’t sure if rebooting the TV would help update the Netflix changes, so I just did so anyway.

Just tried a test-run with Mandalorian on Disney+, which does display the “Atmos” logo, and the Sonos app still indicates a 5.1 situation.  This is the primary (only, really) way I know how to gauge what codec is being employed.  I have done a test-drive on roughly a dozen shows/films that are supposed to be delivered in Atmos and I haven’t been able to see this change reflected in the Sonos app.  I haven’t tried to do anything with the BluRay player just yet, but will prolly get to this later this week.

By the way, the sound is AWESOME with the Sonos, I am loving it.  But I would like to achieve Atmos when/where possible.  Thanks again.

 

I saw some chatter that eARC is buggy on Sonys.  Try turning eARC off, just use ARC.  Then pull power on the TV and wait a minute, then plug it back in to force an HDMI handshake.

Does the Sonos app display “Dolby Digital Plus 5.1” or “Dolby Digital 5.1”? If you test the film Don’t Look Up on Netflix, what audio is displayed in the Sonos app?

You might also try disconnecting and reconnecting the HDMI cable and unplugging the Arc for a couple of minutes. Also try turning off eARC and see if it makes a difference. Then test again with eARC set to Auto.

Thank you, Guitar.  Oddly, Don’t Look Up is listed only as 5.1 on Netflix, though I do have the premium sub there.

On Disney films that ARE marked as having Atmos available, the app still reads Dolby Digital 5.1.

I bought a new HDMI cable thinking this might solve the problem, but no dice.  I’ve done a factory reset on the audio settings and then adjusted everything to where it should be and I’ve just turned eArch off as you suggested.  Rebooted both devices several times, etc. etc.  

I think at this point I’m just going to give Sonos a call.  I am also having difficulty when attempting to connect a new (Sony) BluRay player to the TV - I haven’t set the player up yet or even powered it on, but just plugging it into the TV disables Sonos.  I’ve just discovered an HDMI CEC-less adapter and I’m thinking this might solve the incompatibility problem between the two externals, but I guess I’m going to ask Sonos first before buying yet ANOTHER thing, here. 

I do appreciate all of your help and I am still mighty impressed with Sonos, but it would be nice to have things functioning properly one day.

Netflix senses what your TV/audio device can support and displays it accordingly.  So your TV doesn’t think it’s connected to an Atmos capable device.  Try unplugging the TV from the wall, wait a few minutes, then plug it back in.  That will force an HDMI handshake.  

That’s weird, because Disney DOES display the atmos logo under the titles.

I will give this a try, however.  Do you feel I should leave the Sonos units plugged in and attached to the TV as I cut the juice to the television?

Thanks again.

Disney always displays 4K, Atmos, Dolby Vision, etc.  Only Netflix's display is dynamic according to the system capabilities.

Yes, leave the Sonos plugged in. Only one power cut triggers the handshake, and it's the TV that has the problem.
