If not, then you might want to consider purchasing a new headset or separate microphone. Test if you get similar noise with a different headset. Are you using onboard sound? or do you have a soundcard installed? EMI noise can originate from your soundcard or cheaper headsets. What should I do ?Įarthing should not matter. I just wanted to know that does it matter if there is no proper earthing of electricity in the house, could that be the reason. Good way of ruling out if it is a headset or a pc/settings problem. Do you have a laptop or someone else's computer you can plug your headset into to try.
