so I saw today that tvos now supported Dolby Atmos, so I decided to buy another apple TV for the living room - my wife has been using one in the workshop for a while now.
I have a load of movies on my server and want to be able to stream them - a lot have Atmos.
I saw this video
but when I enable passthrough on the audo for Infuse 5 Pro I do not get Atmos or even 7.1 from my 4k HDR Atmos ISOs
Can somebody please explain what is happening.
