So, I own a CROSSHAIR V FORMULA-Z mobo and there are 6 audio ports... mic, left, middle, right, blah blah blah...
My question is, what kind of setup would require the use of left, right, middle, sub? Are their speakers that could be powered over these ports through just a 3.5mm jack or do these companies just think you may want to hookup multiple sets of self powered speakers to your computer? I wouldn't mind having a neat surround sound setup in my office if I wouldn't have to plug a bunch of power cables in either. Something just really interests me about these ports, as if they have some real potential by themselves instead of just being something I use input / output ports and pondering over the other 4.
