Sound doesn't work

The sound doesn't work on my AcerAspire XC-605.  It has, for the most part, worked until just recently.  It's the speaks specifically.  Everything I've tried indicates that the sound is unplugged.  I'm new at this and technically challenged.  I see three cords plugged from my computer to the tower, and I can't see anyplace on the back of the computer to plug anything else in.  It would help if I knew what the cord looks like and where it plugs in.  My warranty is up, and it costs $100 to get support help.  Is there anyone who can help me?
