How can I achieve a sorround sound on my PC connecting to a DVD Home Theater using the Home Theater's connection? Does it need to be connected to the RCA? Can I use the digital in of the Home Theater and does it enable sorround? Please help. My PC only has the analog sound card for now. I'm planning to buy a sound card or TV tuner if that helps. I have a Samsung HT-D330 without the HDMI connection. I use my Samsung LCD TV as my monitor with just one HDMI slot on it. What to do?
