I've got a Samsung HDTV 30" widscreen. I love the TV. The only problem I have is that I'm trying to get the digital audio out to work. I plug the fiber optic cable into the tv, and then to my receiver, but for some reason in the menu of the TV it won't let me enable it. I'm not sure what I'm missing. I thought it had to do with the signal I was sending to the tv from my different sources, which are a DVR cable box (using an HDMI cable), a PS2 using component cables, and an Xbox (also using component cables). But I've tried all sources and cannot enable the digital out. Can you guys give me a hand?
