Yes, I can get Atmos from my LG 4K TV HDMI eARC to my Denon AVR, but only with certain apps, such as Disney+, HBOMax, etc. Atmos does not work with the Apple Music app loaded to the TV (for that you need the Apple TV 4K player). I cannot test Tidal since I do not have a Tidal subscription.I do not have a subscription to Tidal or any other streaming service except a free account at Spotify.
I did buy a TV late last year that was touted as being Dolby Atmos capable. All I can find in the setup and the meager manual is how to turn it on
Skimmed through the posts but not sure I saw anything specifically about streaming Atmos (through the tv) except with Apple TV.
Wondering if others whose tv is "Dolby Atmos" capable are having any luck with it and Arc or eArc connected with their AVR getting it over their HT?
Barring that do Tidal ever offer trial periods? (Dolby Atmos content)
