load-module module-echo-cancel
Gday @sma_coding, Welcome to the community!
A faulty/weak/bad battery can cause a static/hum/squealing noises.
Also a faulty charging board, due to faulty battery/etc.
If the battery is ok, try recording without the charger plugged in, Or try removing the battery & run on AC only.
Also double check the plug on the microphone is fully pushed in.
Let us know how you go.
thanks Ocka
yesterday I tried the same mic on H.P ELITE Book it worked will
today when I get home I shall try to stop using the AC cuz the battery is built in the laptop I hope it works
but what else can I do if it doesn't work
Is the 3.5mm jack on the Dell dual purpose mic+headphone?
You could from terminal run alsamixer
have a play with the "loopback" channel setting i.e. try both enabled or disabled.
Also try
sudo ubuntu-drivers autoinstall
then
reboot
Just a follow up on Ocka's post.
Make sure your Software Updater points to "Main Server" not a local/regional server for best results.
Made me think,
Also look in alsamixer or audio pulse, & turn down the " Boost " on the mic, then adjust the mic level to suit.
Hope this may help
I'm offline, Bed time 
I tried everything nothing new
Could you please tell us the spec's & age of the laptop?
Are you dual booting or clean install?
Do you have another mic to test with?
If so try the 2nd mic in the laptop concerned.
Do you have a usb/3.5mm adapter to test for a faulty port?
Please open HDA jack retasker, set the port to Override.
First thing first thank you from the bottom of my heart that you try to help me
secondly sorry for my weak English
Thirdly about the laptop..
it's August 2020 production
Dell latitude 5480
core i 5 Gen 7th HQ
8 Giga ram ddr4
it has type c port (I don't know what does it mean)
three 3.0 USB ports
it's built in microphone, I tried it there's no noise with it but the sound not professional as Boya by-m1 microphone
about the 3.5 adapter or USB I don't understand it (sorry for my weak English)
P.S..
I use Boya by-m1 microphone on hp elite book 6930 15 yrs old laptop with no problems

Dell website states the 3.5mm jack is "Audio Combo Jack", so answer = Yes.
So where's the answer to the problem
I know the audio socket is used for both mic and hand free
In your Zorin>Settings>Sound. What do you see there for input device/s when mic plugged in. Post a screenshot.
Also a screenshot of your alsamixer would be of interest, but hit [F5] to show all sound channels first.
I am wondering ifjackretasking would do the trick for you, but I have never used that myself. Maybe someone else on the forum can help.
All of that has no use
But thanks alot
could any one help in plain words plz
From that screen in terminal, can you please tap the F5 key?
