Please help! My Arc is hooked up to the eARC HDMI on my Samsung TU8000, but I’m not getting Dolby Atmos. I’m trying it on Dolby Atmos supported movies on HBO Max among other things supported. My app says I’m getting Dolby Multichannel PCM 2.0 when trying to stream Dolby Atmos shows. My current Samsung settings are; HDMI eARC mode is on, digits output audio is on auto, Dolby Atmos compatibility is on. Is there something I’m missing? Support diagnostic# is 1678696515. Any help is appreciated!
