Hi. I'd really appreciate some advise, please. I'm running a Samsung Series 4 television, Yamaha 2200 sounbar with a new Chromecast plugged directly into the sound bar. Picture and sound from Netflix are fine.....but.....whilst Netflix states the programs is broadcasted in 5.1 the sounbar doesn't appear to be receiving in 5.1. Any advice or help would be greatly appreciated. Many thanks, Ian.
