I have a Buzz TV XRS4500 connected to a Denon X3400H receiver which supports ATMOS. I have a 5.1.2 setup. When I look at the source info from the BuzztV it alwas shows up as stereo only. No matter what I play. Even If i play a local file/movie which is either 5/1. 7.1 or ATMOS - the input to the receiver always states stereo and then my stereo upmixes this to ATMOS.
Does this box not support multichannel audio natively?
