Hi, new here and looking for some help. Have an LG SN7CY Soundbar, dolby atmos capable. Have my sony ubp-x700 4k player connected directly to it. Tv and 4k player both have sound output set to auto rather than pcm. All should be ok? But no atmos when playing 4ks.? No atmos logo pops, just the dolby vision. Get atmos through the likes of Netflix fine. What am I missing?
