In many cases one can manipulate the file extension on any given file independent of the container to get any given media player to see (get fooled by) the file and play it when it otherwise wouldn't recognize the file type/extension. Mediainfo ID's the container of this this file you created as MPEG-4 and the codec as E-AC3.
Related to all this is the concept of codecs vs containers vs file extensions in terms of what's going on here. I'm sure many other platforms and players would do the same. I played this file in Kodi on my Nvidia Shield TV connected via HDMI to my Denon AVR-X3200 receiver and got Atmos audio with no video.
If you have a Dolby Atmos capable receiver try to bitstream this. ac3 file with Dolby Atmos based on the Dolby Digital Plus codec. So I want to prove that you can wrap E-AC-3 JOC inside a. E-AC-3 is 'Dolby Digital Plus' and E-AC-3 JOC is 'Dolby Digital Plus with Dolby Atmos'.
