It seems to be content issue, possibly Apple pulled atmos streams for now?
I can playback Atmos in VUDU app,
you need to make sure to select UHD playback in vUDU settings, that is off by default.
also it seems a bit buggy. Rewind looses sounds sometimes, switching to other apps and back seems to restore it.
also purrchase should be done via browser, VUDU app won’t allow it on appletv
hope it helps!
When setting output to atmos, the format is switched to PCM. This means that the output is locked and the atmos receiver can only play the number of channels recorded. When going back to Dolby digital, atmos turned off, Dolby Output (bitstream).
i can’t figure out how to select atmos and not Have PCM activated. Any ideas
I have a Onkyo TX-NR656. During Beta 2, I was able to view Dobly Atmos content. Apple has seemed to pull the Atmos content back. I'm not sure why.
