I'm having a problem with hy laptop computer. I've plugged my headphones into one of the two headphone jacks on the side, and now, even with nothing in it, one of them doesn't show as Unused (and therefore, no sounds play from the speakers). Nothing broke in it, the sound even comes back SOMETIMES for a very few seconds where it stops recognising the headphones as being plugged in (even if there's nothing in it!) but goes back out after.
Anything to suggest?
