I have a Compaq Presario with front inputs for headphone, mic and input. My 18 month old (gotta luv 'em) broke the tip of my headphones off inside the headphone input jack and now the speakers won't work because the computer thinks that there are headphones plugged in and won't put sound out to the speakers. I went inside the box and unplugged the front inputs thinking that would solve the problem until I can buy new jacks to install. After disconnecting them there is still no sound from the speakers. Is there a way to turn off the front inputs so I can get sound from my speakers again?
