are these analog mini-phone jack headphones, or USB headphones?

If the former, it sounds like it could be a hardware problem to me, 
maybe a mechanical issue with the headphone jack.    are you sure the 
headphones work on another sound source like a ipod ?   are you sure the 
headphone plug is fully inserted ?

the mini phone jack itself has a mechnical switch in it that opens when 
you insert a plug, this disconnects/mutes the sound from the speakers.
