Did you ever get this issue resolved or answered? I have the same issue and don't know if I am getting Doby ATMOS from the speakers. Please advise if you were able to find an answer. thanks.
Will someone help us with this! I call samsung they tell me to call lg. I call lg they tell me to call samsung.
When I connect q950t soundbar to samsung tv it produces atmos. When I connect to lg cx it says it's producing earc. Can we get a tech on this please?
That's not a solution thought. Passthrough is how it SHOULD work (and does for LG sound-bars like the SN11RG). Auto adds signifiant TV-side processing and will introduce severe lag to the sounds (i.e. the picture will arrive 'before' the sound) that cannot be fixed as all delays are sound-based.
AUTO is not a solution - there needs to be a firmware upgrade that ensures Samsungs' SBs work with LG's (wonky) EARC implementation. Disable EARC (to ARC) for a minute on the TV, and select Passthrough again - you'll see that Atmos again works in Xbox (Apple TV 4K has the same issue).
I have the same problem. I'm using an LG OLED77CXFNA + HW-Q950A and I'm having trouble activating Dolby Atmos on my Apple TV 4k and Xbox Series X via eARC connection. Which one is responsible, LG or Samsung? It seems that both companies don't like to work together, seeing that this has been an issue that has been neglected for quite some time.
