When I was digging out few things, found an unused Acer speaker pair. I have a Compaq Evo. Tried to plug the speakers. The sound from the PC goes off but nothing comes out of the speakers. I think I am missing something. Is it the power for the speakers? There is an outlet in the back of one of the speakers. Not sure if that is to be connected somewhere in the PC.

Power outlet is supposed to be connected to a power outlet..... to power on the speakers.. unless they are those "portable usb powered ones" ...
