The headphones work, yes? If you unplug the headphones, and plug the speakers in where the headphones were plugged, what happens?

It seems if the headphones work but the speakers do not from the same plug, then you have a problem with the speakers. I have forgotten to plug the speakers into the wall before, and also forgotten to turn the volume on the speakers up before.
