I'm considering buying the new Apple TV. Is it possible to be sure it will pass Dolby Digital 5.1 through my TV to the Playbar before I buy? The TV is a Sony 55w828b. When using the Netflix app in the TV I get DD on the playbar, but using the Chromecast from the Netflix app on my phone I get stereo. I’m not sure if this is equal to the TV will not pass DD through the HDMI to the toslink. PS. I know that TV can not display 4K or HDR and the Chromecast is the first generation, not the round one.
