Most Windows 8 laptops are in warranty. I'd call it in for repair if the short blast of canned air on the jack port doesn't help.

I have a Dell Inspiron 3521 running Windows 8. Recently, my headphone jack stopped working. My speakers work fine, but every time I plug in my headphones, my computer doesn't recognize them and the sound comes from the speakers instead of the headphones. I tried various headphones and even bought new ones, but none of them work. I've checked for updates, and tried troubleshooting, but no problems are detected. Sometimes, the I get spam notifications of my headphones being plugged in and unplugged. I think the problem might be my headphone jack as, if I put the headphones a certain way, they temporarily work. PLS HELP!
