If you are playing Dolby Atmos music or a movie on a device that supports Dolby Atmos, and your TV can pass through Dolby Atmos, you will hear Dolby Atmos audio from all of your speakers.

Ok so I wouldn’t need to upgrade the sub to gen 3? Or the ones to one so’s?

how do u know if the arc is playing Dolby atmos?

my LG tv is only 2 years old and says it has Dolby atmos

No, you do not need to upgrade the Sub or Ones.

What model LG do you have?

The Dolby Atmos logo will appear on the Now Playing screen in the Sonos app when you are playing Atmos audio:

Ah ok

im not sure the model till I get home

it is oled though 

I play my music though Apple Music 

does the beam support all this? I have it upstairs

Also by not upgrading the ones or sub they would still play in Dolby atmos?

Userlevel 7

No, the Beam does not support Dolby Atmos audio. The Beam only supports up to Dolby Digital 5.1 audio.

You do not need to upgrade the Sub and Ones to get Dolby Atmos audio. It will play out of every speaker in your 5.1.2 Arc/Sub/Ones setup as long as you meet the criteria in my original post.

Currently, the only way to listen to Spatial Audio/Dolby Atmos music from Apple Music on the Arc is through the Apple Music app on an Apple TV 4K connected to a TV equipped with HDMI eARC or an HDFury eARC adapter.

I was just pointing out that you need an Apple TV 4K and a TV equipped with HDMI eARC to get Dolby Atmos music from Apple Music to play out of the Arc.

The music won’t play in Dolby Atmos if you are streaming it from your phone, computer, or from the Sonos app.

Just one more question 

By connecting the arc to the tv

does it automatically play 5.1?

for free view or Netflix?

Userlevel 7

If you want 5.1 audio to play out of your speakers, you need to make sure your TV is set to the proper settings to pass through 5.1 audio. You also need to make sure your source is actually playing in 5.1 audio and not stereo. I’m not sure if Freeview has a lot of channels that support 5.1 audio, but Netflix has plenty of shows and movies that are in 5.1.

According to my research, the LG B8 should be able to pass through Dolby Atmos audio.

TV Settings:

  1. Be sure you have the latest firmware installed.
  2. Be sure Simplink (CEC) is enabled.
  3. Run TV Setup in the Sonos app and connect the Arc to the TV’s HDMI ARC port.
  4. Under Sound, set “Dolby Atmos” to On.
  5. Under Sound Out, Audio Out should be set to “HDMI ARC”.
  6. Under Audio Out, Digital Sound Out should be set to “Auto” (or “Pass Through” if available) and Simplink should be “On”.

For some reason Dolby atmos is greyed out

but I think it’s all set up

Userlevel 7

Do you have the latest firmware installed?

Is Simplink turned on?

Does the Dolby Atmos option change when watching a Dolby Atmos source like a movie on Netflix?

FYI… you need a premium Netflix subscription to get Dolby Atmos audio.

So when I play a movie on Netflix with Dolby atmos

it says Dolby atmos on the sonos app

Good. That’s what you want to see. It means everything is set up correctly and you are getting the best audio that you can get from the Sonos Arc.

that dolby atmos switch is only enabled when using internal speakers, other settings appear to be fine, you should see the atmos logo in the sonos app when playing content with atmos soundtrack from internal apps like Netflix or Disney+. But keep in mind that for having atmos from Netflix you need the UHD plan

yes, but I needed to turn up the volume of the height channel in the sonos app, I have it at +3 now. In some scenes there was sounds clearly coming from the ceiling, also the overall sound seems to be more immersive

Oh is it worth me turning up the height volume on mine? 
I didn’t know what that option meant
