Try inserting the headphones again. Give it a little wiggle back and forth (don't go nuts and really wiggle it enough to break it off). Might have to do it a couple of times. The notbook uses an IR light to know when something is plugged into the jack and for whatever reason it still believes there's something plugged in. Might even try a different set of headphones if you have some.
I'm having a similar problem -- the internal speakers are not working. It shows "No" sign (i.e. a circle with a slash through it) when I press the volume up or volume down buttons -- and there's no change in the level of sound graph on the screen.
I can use my headphones just fine, but when I unplug them, it's like the MacBook can't find the sound card or speakers. Also, the red IR light is shining from the headphones jack.
I tried wiggling the headphones in the jack -- no dice...
i believe the "IR" light is actually the digital optical output light (hint: you can't see InfraRed aka IR). I inserted a digital optical cable into the jack, waited a few seconds, and removed it. This solved the problem for me.
