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.

Exactly. It will check the TV and Soundbar are communicating correctly,

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!

    That may well work for some... In my case it was a new motherboard (thankfully richer sounds did 5 years warranty!)

    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.

    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.
