HP Pavilion 17-e020dx - How do I change audio/microphone jack?

I usually connect my computer to the stereo through the headphone port for sound. My dog caught the cord and yanked it out hard, succeeding in killing the cord. Funny thing is.. the headphones still work, but I have no sound on my computer speakers now. The jack works with a little love, but is touchy and loose. I have searched and looked and found just about nothing for replacing the sound board, jack, or parts. I need help. I have tried just about every software fix including refreshing. (Win 8) 64.

I have been living with it for a couple months, but it'd be nice to have sound. A tear down guide would be good.
