It might be your soundcard driver issue,are you using the updated drivers?
So i bought recently whole new pc, and im experiencing this issue while on teamspeak3 or trying to record anything. It's like im barley hearable on ts. When i try to boost the microphone its getting better, but im getting along with it terrible static noise, that gets louder with each second im using mic. I'm using on board sound card included in my Motherboard Asus Z170 Gaming.
I'd like to notice that the headset is perfectly fine, it was working all good on my old pc (Asus M4A MoBo).
