Hi everybody, I've got the old Macbook model, circa 2006. My audio port's been broken for awhile now, and I recently got a 5.1 surround sound system. I've been playing music through my iPod, of course not getting the full surround effect, but would love to be able to hook the Macbook up to this system, be it in full surround or not. I've gotten the runaround from people at Radioshack, Best Buy, and was even led to buy this silly part which has done me no good: http://www.amazon.com/USB-Auxiliary-Audio-Input-Jack/dp/B002ZNXX7C Is there any way I can hook up my speaker system to the laptop via USB? and if so, can you walk me through it with which product(s) I need as I'm really just exhausted over this issue.
