Reply to Headphone setup mixtrak pro

Hi everyone

I am sorry if this has been posted before. Here is my scenario.
I bought a Mixtrack Pro it came with a usb cable and a disk that only had asio4all sound drives plus the actual midi device. The set up was relatively easy just install traktor 2.6 and select Mixtrack Pro as my midi controller. It was smooth the hardware and software are working perfectly. Now the problem comes with setting the headphones. I have looked at all sorts of youtube videos and still no luck. My setup is this,

Laptop: HP Compac Presario CQ57
Controller: Mixtrack Pro
Sound: I am using my soni creative speakers plugged to my laptop.

I need help what am I missing? Is there a simple step by step guide for dumies. I am a noob
