I have a UN50NU6950F smart TV. I want to be able to use headphones at night so I don't bother others in the house. I've tried Bluetooth streaming with the digital audio out and now I have a digital to analog converter and wired headphones. Either way I can get audio from Directv but when I try one of my streaming services (Netflix, Amazon Prime, Apple TV) I get nothing. It makes no sense since they all work with the TV speakers. Any ideas on how to fix?
