Recently I've experienced something I find pretty weird. Sometimes when I take out my headphones from my MBP, there suddenly is no more sound. I have to reboot the computer for it to work again. I have the same problem with external speakers as well. I've thought about it and guessed the problem was in the jack. Maybe the computer does not fully recognize that the headphones have been taken out so it "thinks" that the internal speakers should stay off. Btw, it doesn't happen all the time but since I regularly switch from headphones to external speakers it is pretty annoying. Has anyone else experienced this? Have you heard of anyone experiencing this? Any fixes? Advice? Anything? Thanks!
