Question USB microphone started to buzz after 2 months

Dec 4, 2019
(Sorry for my English. If you don't understand something you can ask)
I'm using Auna 900b (USB mic) for something like 3 months. Everything was great, i mean no noises no buzzing no nothing. My voice was clear af. So after something like 2 months my mic started to make some noises like buzzing (

I tried:
-switching USB from 2.0 to 3.0 and from 3.0 to 2.0
-another PC
-unplugging another USB cables and leaving only mic
-using audacity (maybe it's because OBS but.. No)

While using Team Speak 3 my voice is like quieter (i mean VERY VERY quieter) but still sounds very good.

I made a video (in case u don't understand me at all hehe)
Video: link

My mic. is setted up like this (while making this video i changed it to 100. But still... it never happened even with 100)

Problem can be that i don't have Audio Manager (like realtek somenthing)
But i installed it like 3 times


I mean. This thing

It is possible that some Windows Updates made this happen?
What should i do?

Like... I don't want to buy another mic after every 3 months
