Speakers don't work, but head phone does

So, I have a Creative Insipre 5200 (one of those shitty 5.1), and I havn't used the speakers in a while, only a headphone though the headphone jack.  Now None of the speaker or subwoofer generates sounds at all! WTF?!?

I know that it was OK a few months back, since the subwoofer worked fine (speakers not hook up).  When I decided to hook the satelite speakers up today, nothing would work, but sound will come out through the Head phone jack of the Volume controler when pluged in.

I'm sure that everything is hooked up right, so anyone know what the hell is up with my spekaers?  Or did they simply just crap out? (unlikly, only almost 2 years, and hardly used for the past almost half year)

Thanks

Maybe you want to hook up the speakers instead of the headphones, or failing that, unhook the headphones.
