Built-In Speakers Sound Output Missing.

I currently have no sound from my macbook pro's built in speakers. When I try pressing the volume buttons on the keyboard, a small "blocked" sign comes up (like on no smoking signs, the circle with a cross through it). When in sound preferences, under Output, there is only "Digital Out", where there should be Built-In Speakers. When i put in headphones, sound comes through as usual, it is merely the speakers themselves which will not work.

please please help!

macbook pro 17", Mac OS X (10.6.5)
