So, I've been looking at sound cards for awhile trying to figure out how the hook-ups work. I only know what the green (speakers) and pink (mic) do, but on a sound card I see orange and blue and a few others, so what are they used for? Does each channel (speaker) get its own jack? Also, I have a motherboard with build in 5.1HD audio, but it only has a green, pink, and a blue jack? I have a 3.5mm to RCA running from the computer to an only Sony 5.1ch surround amp, so does this mean I'm getting TRUE surround? Or is the computer sending a basic signal to the amp then the amp just boosts it? My control panel says I only have a 2 speaker set up and no other options to change to 5.1ch to match the amp. I'm a pretty big audiophile, accept when it comes to computer audio so any help or answers would be appreciated!
