Getting Dolby digital plus 5.1 on arc but not dolby atmos
Just bought a new arc and trying to get it fine tuned. Playing Jack Ryan on Amazon prime. I am able to get Dolby digital plus but not Dolby atmos. I using Earc from LG Oled C 65” to Arc. I think I have everything switched properly. Sonos said Dolby Digital plus 5.1 is the same as Dolby atmos.
