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.

Here are my settings:
SOUND:
Dolby Atmos ON
Smart Sound Mode OFF
Sound Out Audio Out (Optical/HDMI ARC) You have to click in here and turn Digital Sound Out = Auto and SIMPLINK (HDMI-CEC) On
Magic Sound Tuning OFF
DTV Audio Setting AUTO
AV Sync Adjustment OFF
Did you set the Arc up with Simplink in the Sonos App?

Yep - I got my Arc yesterday and it works on my B7.
Have you double checked that you’ve unchecked the ‘HDMI Deep Colour’ setting on the HDMI channel the Arc is connected to? You need to set the TV to HDMI 2 to do this, and go to Setting - General - HDMI Deep Colour if I recall correctly.
Just to check with your B7V - did you get sound immediately on plugging in the HDMI2 as well or have to fiddle with settings? No sound at all for me as yet! On the plus side the more people it seems to be working easily with the better case I have to say to LG that they need to fix my TV for me I guess!
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!
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.
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.
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

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

my guess from
Settings>System>(choose room with Arc)>(scroll down to Home Theater section) click on TV Setup and follow the directions.
LG have finally got back to me and apparently they think its a faulty motherboard which they will replace at £399!
Fortunately I bought the TV from Richer Sounds who will collect tomorrow to repair for free!

Hi. I fixed the issue by
Go to General options and switch off Simplink
then go to sound and switch back on hdmi arc and then the Sonos app showed atmos
Tv LG B8 STB
That may well work for some... In my case it was a new motherboard (thankfully richer sounds did 5 years warranty!)

When you say no Atmos..Is there no sound coming from Arc when you choose Sound out - HDMI ARC ?
Hi. Just got my arc and set it up with a lg b7v. One thing I noticed is that netflix native app only shows atmos with original english sound track. If i switch to my native tongue i get dd+. I don’t know if that explains some of the observations made in this thread.
I read on the Tidal support page that it must be eARC for music Atmos. I also have a 2017 Oled and a Sonos Arc. Netflix and Prime Atmos works, however.
