Hopefully someone can help me here. I have a Gateway GM5474 with ntegrated 8-Channel (7.1) High Definition Audio. How do I use it? What kind of cables do I use to hook my speakers up to it? Do I use 3.5mm mono or stereo plugs for each input directly to my speakers or do I need some kind of mixer? Can I simply plug my subwoofer into the subwoofer jack and so forth? I can't find anything on the web to explain this to me. I want to use my speakers from my 7.1 home theater system that no longer works and plug them into my computer for surround sound. Any help would be appreciated.
