Hi all! So I have http://www.pioneerelectronics.com/PUSA/Home/Home-Theater-Systems/HTS-GS1 which I use for my PS3, and have recently decided life would be easier if I used it for my PC as well. My question is what sound card would be a good choice for using optical out? I want to use TOSLINK I believe, although I'm not entirely sure. Any Help would be greatly appreciated! Edit: The HTS-GS1 also has coaxial input, if that matters. I'm so confused! Edit 2: Just noticed my TV has an optical output. Since I'm using HDMI input from my video card, is it possible to simply hook up the surround system to this optical out from the TV?
