I'm checking the Dolby Atmos support with the official demos from the usb, and only 2 out of 10 actually give any sound at all! Only one showed "dolby atmos" on the q70t soundbar. All the other files showed the message that audio is not supported. I checked those on my pc, and all of them had dolby trueHD with dolby atmos audio.
Next I tried demos with several audio tracks, in most cases only usual ac3 is played.
I found out that Dolby Digital Plus with Dolby Atmos in the format of E-AC-3 JOC were played well, while Dolby TrueHD with Dolby Atmos in MLP FBA 16-ch where not. The first one is lossy, and the second one lossless.
So I'm feeling frauded by misleading advertisements as almost nothing claimed actually works!
I'm getting really disappointed with Samsung!
