MAC OSX Built in Speakers aren't working? But the headphones are?

Hello,

So I had a little problem earlier with my Macbook. The sound wasn't working and it showed and "x" and a full sound bar. Well I went to look up what it was and found not posts except that someone said their head phones worked, so I plugged mine in and vala! sound, but wait when I pull them out there goes the sound again. Thankfully I don't like sunlight so it was dark and I perchanced to see a red light coming out of the headphone jack, hum ahaa sensor! So I just blew it out with a can of air duster and "poof" the sound was back on. So just thought I'd post just in case anyone else comes across the same problem!


Awe, speaking of my macbook, hear is a video that I made using all the cool features of imovie '09. Enjoy!
