Headphone Jack is not working when i plug in a pair of Speakers with their own dedicated 3.5" jack. It used to work before- speakers work fine with other devices. The headphone jack port in my MacBook pro is not even recognized/shown in the System preferences/Sound option (just internal speakers are shown): sound does come out of the internal speakers but my MacBookPro just does not seem to recognize that there is a 3.5" jack port. I re-set the PRAM and VRAM already to no avail. Does that mean that it is broken and needs to be repaired? does that mean that i need to change the entire logic board?

MacBook Pro, Mac OS X (10.6.8)
