Hey I know this is more than 2 years later, but I was having the same problems until a couple minutes ago, but then I realized that the problem is setting the TV's input source correctly. I had my TV (Samsung, if it matters) source set to DVI PC, and it didn't receive any sound signal. I've then set it to BLU-Ray, I did get sound, but sharpened image. And then I've simply set it to PC, my image settings are back, and now I have sound as well! My problem initially started from my onboard soundcard swapping the left/right channels and having issues with the 2.1 system that I installed after my old receiver died recently. Hey, hope you solved your problem by now, anyway!
