Hello, I've recently bought the Samsung Js9000, and connected everything up fine using the one connect box. The only issue is that when I've used the Av adapter leads to connect my ageing Sony amp via the red and white leads it doesn't work. Is it time to invest in a new amp with USB? Or Digital optical? Or is it a setting on the TV that I need to change? Anyone that has an idea, or has solved this please let me know. I'd rather not have to fork out for a new amp, as I love my old Sony. But if needs must.... Thanks!
