Static headphones on Blade 17

Hi,

After years wanting to buy a Razer laptop I finally acquired a Blade 17 and I'm experiencing an issue.

When using headphones plugged into the 3.5 jack I can ear static.
When no sound is playing for a few seconds it disappears but whenever any sound is playing again it comes back and it is highly annoying.

I've plugged the headphones on my phone an there is no static.

I'd appreciate any help.

Regards, killy.
