are you talking about the headphone on the CD drive? If so, you need to hook the cable up from the back of the drive to the sound card or the CD-IN on the MBD if onboard audio (probably CD-IN on the sound card, too). Its usually 3 little wires.
If you argue with an idiot he will drag you down to his level and beat you with experience.
