I have HP j120 TX model. It has only one jack for the headphones. But most of the 5.1 headphones (e.g Roccat Kave) has 3-4 pins.
So please tell me how to configure such headphones with my hp notebook. Any suggestions on the model/brand of headphones giving 5.1 output (under $150) wich are compatible wih single jack hp notebooks.
