First of all, sorry for the extended length of the into question, but I wanted to get more to the point from the start. Powering down power cable attached/unattached, clearing PRAM, jiggling the headphone jack. I think first of looking at the use of the jack prior to the not working experience. For myself, I use the headphone jack as a line out to my sound system, meaning that is is normally in the headphone jack mode. Now it won't change to internal speakers, and just like the others, not a visible option to change. Does anyone have any new light to shed on this issue?  It seems to be affecting many MBP users. Thanks
