How do I know if i have a sound card that will work with a 5.1 Surround sound system?





I am thinking about purchasing the Logitech X-530 5.1 surround sound system and I heard that you need a 5.1 sound card installed to make it work or sound better? How do I know if my computer has it? I have like 6 holes in the back of my computer with different colors so i dunno if that is the sound card. I looked in my drive and saw that my sound device is Sigmatel HighDef Audio Codec. Will this work? If not can i purchase any sound card as long as it has 5.1 in it? please reply asap thanks.
