[AC Question]

Earlier in the day I posted this, my Alcatel OneTouch Oixi 7 played audio thru headphones just fine. However, this evening, I went to go watch some Youtube and only the speakers would play, despite the fact that I had pligged in the headphones and the symbol had popped up, albeit a few seconds.

Any ideas? I need headphones because I tend to sit in wi-fi cafes the better part of Mondays and I doubt any want to hear the same things I am watching.
