Install the right audio driver for your computer
If for any reason it’s hard to get the official driver and the one you have installed isn’t working correctly, please follow these steps in order to adjust the default driver:
First, disconnect any other connected device as much as you can and leave only your microphone or headset connected.
Right-click on your Start button or press Windows logo key + X and select Device Manager.
Expand Sound, video and game controllers, right-click on High Definition Audio Device and select Update driver.
Select the second option: Browse my computer for driver software.
Click this option at the bottom: Let me pick from a list of available drivers on my computer.
Select High definition Audio Device and then click Next.
A warning will pop up confirming that you are making a change to this driver, please click Yes.
Now reboot your computer and check if the microphone works.
