Question / Help Problem with sound during livestream

[Aurenqt]

Hi guys, it's since a while that i'm streaming, and recently i've decided to use Skype too during it. But here comes the problem..Somehow there is a noize during my whole stream; and for my low experience with OBS i've no idea of how remove that background noize.
For be more detailed, here there is my last livestream with that noize:

Hoping to find a solution of this, thanks in advice :)
Best Regards

It's from the mic - do you have your mic plugged into the back of your computer or something? It sounds like general interference (though quite bad admittedly)

Actually i've my headset plugged to the back with my computer, with an USB cable that connect mic/head together in the same UBS slot

Hm, USB devices shouldn't usually do this, sounds like a motherboard quirk. Have you tried swapping it to a different port, or doing it with the other devices? That can sometimes help. (also if possible update your motherboard drivers, that can also somewhat rarely help out)
