How to remove the background noise of the PC microphone?

Question

Iron

Interested in the issue of eliminating background noise.
I think many people have come across a situation, for example, a Skype conversation is accompanied by background noise, or just recording audio on a PC / laptop microphone.
For example, there is a PC and a laptop, when using the connected microphone, a hiss is heard and there is no difference in the quality of the device itself, that is, when communicating through a cheap Sven ~ 5-6 $ or a more expensive Olympus ME-32, the noise is absolutely the same, straight 1 in 1. The difference is only in the quality of speech, on the Olympus it is more natural. The same situation when connecting via ASUS xonar U3 card. But if you use Zoom h1 as a card, there is no noise, the microphones work perfectly.
From which I conclude that the audio path itself is noisy in the PC and Sony laptop. The PC has a good Seasonic power supply, the jamb is not in it, the laptop also makes noise when running on battery power.
Interested in the possibility of correcting the jamb hardware, not software. Buying an external ZK will solve the issue, but this is already a very radical method.
Regarding grounding, I'm not sure if it exists, so I want to ask people who have encountered and solved similar issues.

Answer 1

If this is path noise, then you need to use an external sound card.
Usually, there is always noise and it is cut with noise reduction.

Answer 2

Maybe it's the grounding of your computer, is it just grounded?

Answer 3

I installed Realtek in the settings, checked the "noise suppression" "echo suppression" checkboxes and that's it, the sound is the purest, not the slightest background noise.

Answer 4
