Windows 10: Random Echo Noise

Hello Microsoft, I've been having this problem for awhile now, and I can't seem to fix the issue, I've tried a lot of tutorials but they don't seem to work out, for some reason my mic keeps picking up noises, Example : Random fan noises that's louder then my voice, Crackling noises, and scratching noises, it also picks up air noises, I just can't find where these noises are coming from, If you have any suggestion please send a text massage, thank you!

Random Noise

My computer has been making a random noise since I first got it (yesterday). I found the noise and turned it off, but it is still making the noise. It's really annoying when I'm trying to do things that require my focus. How can I fix this?

 

Echo/Noise during calls.

Hello dear community,

I have a problem with my Lumia 950 DS, when people are calling me they hear some kind of echo or noise. Ive tried to make speaker sound to 7 or even less it doesnt help. I have also removed my protection case from phone - no profit. One thing which helped
me - factory reset, but after some time, with installing some "updates" that problem appeared again.

Has anyone had this problem aswell?

 

Random Alert Noise from Windows 10

Please tell me someone here can help with this I am going to lose my mind...

I have a new Alienware laptop. I am dual booting with linux and windows 10. The windows side is constantly throwing random alerts. The noise is the same one you get when you adjust the volume bar.

Steps I've Taken:
- Ran all the troubleshooters, The audio one does throw me a warning about enhanced settings not working right and should be disabled but does not fix the problem.

• Checked drivers across the system everything seems ok
  

-Clean install

-CC cleaner reg repair

-malwarebytes scan

• Followed the advice presented Here Which talks about downloading the process monitor tool and then parsing for .wav files. Great plan!!!! But... Whenever I run the tool the sound will not happen. Often it will happen just before and immediately after but it WILL NOT detect anything.
  

I finally gave in and decided to just disable all system notifications. But what do you know it still happens.

Im straight out of of ideas. Please someone help.
