Arc with LG B7 - no Atmos

I just swapped out my playbase with an Arc.  It sounds great, but I am trying to get it to play Dolby Atmos content.  I have a 2017 LG OLED B7 TV that has an ARC output (not eARc).  I have found a few streaming sources with Dolby Atmos content, but it will only play through the TV speakers (when switches to internal speaker). Any help would be greatly appreciated.

Checked everything and still no Atmos.  Not sure if the surround speakers are having an effect or that I had a Playbase connected before.  Just grasping at straws at this point.

What source are you using to send atmos?

I have tried Netflix (internal app), Disney+ on 4k Firestick and through Xbox - 4k discs.  I have tried a different HDMI cables for the Arc.  I just tried removing the surround speakers as well.  Still no luck.  I can get Atmos to play through the TV speakers, but that kind of defeats the purpose.

Did the Sonos app say that the arc was working when you set it up?

I don't recall, but I  would assume so.  It sounds great, but would love to hear how much better it sounds with Atmos.

Ok, I figured out the issue.  I was actually expecting the TV to display Dolby Atmos on the screen when content starts playing.  If you are using the internal speakers, it will do that.  I checked via the app and it says it is playing Atmos.  Although it sounds really good, I was actually expecting more height effects.  I also tried the opening scenes in John Wick 3 (4k Blu Ray) with the rain falling and again a little disappointed but obviously much better sounding than the Playbase.  I do also notice slight audio hiccups while playing John Wick 3 that I don’t hear with streaming apps.

Very frustrating.  All settings seem to be correct, but neither native apps nor apps on 4k firestick will play atmos.  TV firmware is up to date.  I am using the hdmi cable that came with the sound bar which I assume supports ARC but will try another cable.

me too with your same problem

I had to do the setup in the Sonos app and it told me I didn’t have Simplink turned on, after that it was fine. Checked I was getting Atmos with Roma on Netflix. All good. Sounds fantastic!

What did you change to get it to recognise simplink was turned on?

my guess from @Andrewnoob’s description is the “TV Setup” in the Sonos app:

Settings>System>(choose room with Arc)>(scroll down to Home Theater section) click on TV Setup and follow the directions.
