OK, I have my TV on one wall and the components on a shelf hidden on the other side of the room. Now, I have one HDMI calbe running from the TV to the surround sound input. I use that one cable to switch between the DirecTV, Blu-Ray and radio/iPod. The TV is a Samsung UN55D7000 and I have it connected to my network. So, the question is, when I want to watch a movie that's on my PC through the TV I can't get any sound. I have to listen through the TV's speakers instead of the surround speakers. Can anyone please help me here and let me know what I need to do to get the sound to come through the surround speakers please. THANKS!!
