Turtle beach sound card

When I plug in my headphones or any other , I hear this weird buzzing noise while listening to music,etc.
How do I fix this

Beside letting us know which TB soundcard you are using let us know where are you plugging your headphone in at?

the green circle in the back of the computer , it is near the wi-fi and graphics card

if there's no solution to this then can you link me a decent cheap sound card off newegg that will work on a desktop computer?

Thanks
