In other words, the Atmos extension gets folded back into the Dolby True HD 5.1/7.1 stream if the Atmos decoder is not detected/enabled in the receiver.

Sounds like you have a source issue if playing any other content seems to work.


So the display on my Denon should say Dolby True HD 7.1, and not Dolby Atmos?


Correct, if in your Denon's speaker configuration/assign mode you didn't specify at least 2 height speakers, the ATMOS and DTS:X formats shouldn't appear in the "support format" line. Is it possible you did assign your rear surrounds as height speakers?

Nonetheless, the signal dropout is likely a handshake issue between your source and the receiver (assuming that you tried playing another source an all-channel mode and got sound out of all speakers.)
