Just received my new Aura box and, so far, very pleased with it. However, I've connected it directly to my Denon AVR via HDMI and set the audio on the Aura to "Audio Output Home Cinema 7.1 etc" but am not getting ATMOS audio when playing back UHD/4K films from the external USB stick.
Does anyone have any ideas as to what audio setting I may have overlooked?
Thanks
