Lg sk8000, Samsung k850, Dolby Atmos troubleshoot

[shaunmartinez121]

Hello all, I recently purchased a 65” lg sk80 and a Samsung sk850 Dolby Atmos soundbar. My problem is when connected via arc I cannot get Dolby Atmos out of my soundbar with known Dolby Atmos content, with Dolby Atmos enabled on the tv and running internal tv speakers I can get “Dolby Atmos”. My question is what am I doing wrong to get Dolby Atmos through my soundbar?
