[HP Compaq dc7700 Small Form Factor, Realtek ALC262, Black Mic, Front] Sound is distorted

[alex]

The microphone inputs dont work, what sound i can get out of them is very over driven and cracks. same with the speaker output in the back of my computer, I'm using version 14.04. I can get perfect sound out of the headphone jack though.
