Hp laptop sound not working on both headphones and speakers

hello everyone, my laptop sound is not working at all.
I was playing borderlands 2 and had skype on and when i plugged in my headphones into one of the two headphone jack the sound just completely stopped working.
I have restored my computer, reinstalled the audio drivers, disable then enable the driver, check if it is on mute, turned my speaker volume all the way up and i still have the problem.
But when i play the video and go to my sounds in control panel, the green bar that shows if sound is playing or not goes up and down so i know the sound works. But i can't hear anything...
my laptop is Hp pavilion dv4-3118tx
Ive also tried putting my headphones in and out repeatedly and it does not seem to work or maybe i just havent done it enough???
I dont think the laptop is in headset mode since i cant seem to hear anything even with my headphones plugged in..
Thanks in advance.
