Hey all, I know this question has probably been answered before but unfortunately I don't have time to go through this whole thread so I'm hoping one of you can help me out. I'm having trouble getting sound from my viera apps (netflix, youtube, etc.) to play through my home theater. I have an optical cable hooked up through the back of my tv and into the receiver. When switching the receiver to tv audio I still don't get any volume. I tried going through the settings, but I couldn't get any results. Can somebody please tell me I need to change? Thanks!
