I have a 720p Panasonic plasma TV from 2006 or so, but my audio runs through a new Atmos-enabled soundbar (Samsung Q70T). If I were to connect either a Roku Premiere or Ultra directly to the soundbar, would I be able to get Atmos audio on movies/shows that offer it? Or would the old TV cause prevent me from getting Atmos audio? I tried a Fire Stick 4k today, expecting it to work, but apparently that only plays Atmos audio when connected to a 4k TV, which was unexpected.
