I had my headphones plugged into my MacBook Pro and the tip broke off inside. There is no way of getting it out, I've tried everything I've read, and fixing it through apple means they will have to replace the motherboard. I've heard I could get a USB soundcard with a headphone jack and plug that into a USB port. What I'm wondering is if the computer will recognize that as where to play sound, as the headphone jack is techincally still "plugged in" and therefore it will want to play sound from that. Is there a way to override it so that it does not recognize the headphone jack and only recognized the USB port for sound?
