Hi, How odd--I just experienced the same problem today. In my case, I'm pretty sure it's because my BP had a weak headphone jack. The headphones have always been loose in the jack for my machine. I have experimented with about 15 other Book Ports through my work, and mine is the only one that seemed to have this loose headphone jack issue. Anyway, I think the jack in mine just gave out. I guess it's back to APH for repairs for my BP...
