How can I make my headphone jack work on my Macbook Pro 15" Retina Display, it quit working randomly
Your speakers not working after you unplug your headphone jack is a dead giveaway that your headphone jack is full of dust or some other kind of foreign substance. Get a can of compressed air (you must be 18 to purchase compressed air, also it costs about $5 per can) from Wal-Mart or Best Buy or another retailer and use it to blow the headphone jack clean and you should find that it works again.
