I have a wifi connected sony bravia KDL-50R550A to view Netflix
I do not get sound coming from my Harman/Kardon BDS 270 sound system when watching a movie ....I can only get sound through my tv speakers
Everything works when watching a dvd/Blu-ray or my cable..
My tv option has the option tv speakers and audio system...when it is at tv speakers it works...on audio system there is no sound
It also has the audio out option where the choices are variable and fixed
And the option Digital audio out with the options Auto and PCM
