Dell keeps a master code for each of their machines. All you have to do is transfer ownership of the machine into your name, if it isn't already, and give tech support a call, and they'll give you the code over the phone. You can transfer ownership at Dell's support site, there a subcategory on the left of the screen that reads "ownership transfer". Here's a link for the tech support number.

If the speakers work, the system is OK as it uses the same amplifier. Try some more headphones and make sure you are not in the wrong socket. Easily done.
