I just got a Hp Envy laptop and I can't plug my headphones into the headphone jack. I've never plugged them in before which is why I'm confused. Right now, when I try to plug my apple headphpones in, only a small part goess in and then they don't go any further. I think there may be something stuck inside the jack. It looks like there may be a small clear ball in there, but I've never seen it before. Am I just using the wrong type of headphones? Or is the ball supposed to be there and I'm supposed to take it out somehow? ANd if there actuallly is something stuck in there, any suggestions as to how to take it out? Thanks in advanced!
