I bought a Dolby Atmos compatible soundbar, but I can't seem to get it to work with my external Apple TV input.
When I play a Dolby Atmos movie straight from the TV, it shows "Dolby Digital+" in the sound settings of my TV (which supports Atmos if I understood correctly), but when I play a Dolby Atmos movie from my Apple TV in only shows "Dolby Digital" in the sound settings.
Can this have something to do with my TV not supported eARC (and therefore doesn't allow for Dolby Atmos passthrough from Apple TV to the Soundbar?), or what else can it be?
