The Vertex2 can’t do any re-encoding for the audio part, only send some custom EDID table if required.
What comes in, goes out un-touched...

When the Apple TV 4k was set to output Dolby Atmos, the HD621/861 did not switch to Cinema mode or anything. When Dolby Atmos was disabled, one of the movies I tested with Dolby Atmos gave me 7.1 surround and was ok for me wink

I’ve watched lot’s of movies with Atmos sound on my LG SL10YG soundbar with the optional rear speakers. Really impressive audio mixing and how this soundbar performs. But, of course at my friend place with full 7.1 Meridian system, I really enjoy 7.1/5.1 surround.

Hopefully for the 7.1/5.1 surround owners, they still will make a 7.1/5.1 soundtrack on movies in additional to the Atmos soundtrack in the future grin
