Weird macbook problem

and everything works normal with headphones plugged in

try going under system preferences and then sound and see what the input source is. chances are it's still set on the headphones even when you take them out of the jack.

I think I got you here. This happened to me last year and it took me soooo long to figure out what happened. I think your problem is that you were using some program (in my case, a video player) with your headphones, and you closed your computer, pulled out the headphones, and then opened your computer again and quit that program. What you need to do is open up that specific program again, plug in your headphones, and then while the program is still running, take your headphones out so that the audio plays through the speakers. Thats what worked for me--give it a try.

Maybe try punching the shit outta the screen. That usually works like a charm.

Hit the "FN" or function button on the bottom left of ur keyboadr. At the same time hit the volume up botton.

yea if you wanna pay $200 a month fixing the pice of shit.

Yeah, I had this problem too. Turns out it's kinda common - apparently the optical sensor in the headphone jack is confused into thinking something is there when it isn't. What worked for others (and myself) was to take the wood end of a match or something like that and actually put it in the jack and poke around until you hit whatever tiny switch is mistakenly tripped.
