Microphone Driver is not functioning well

Hello Jericho,

I understand your concern, and we in Community will try to help you in the best possible way we can.

I would suggest you to follow the below steps and check the status of this issue.

Check your microphone’s drivers

• Type in “Device Manager” in the Search box and select it from the list.
• Expand Sound, video and game controllers
• Right-click (or tap and hold) your microphone device and select
  Update Driver Software.
• Select Search automatically for updated driver software. This option will scan the Internet for the correct version of the driver or determine if you already have the most recent driver installed. You may be
  prompted to restart your computer to install the driver.

Manually turn up the mic gain

• Type in “Sound” in the Search box and select
  Sound (Control Panel) from the list.
• Select the Recording tab.
• Right-click (or tap and hold) on the active microphone input device and select
  Properties.
• Select the Levels tab.

Manually drag the Microphone gain to a higher level and click
Apply.

Microphone issues

Hi Michael,

Here are the possible reasons why you're getting an error "The microphone did not pick anything up" when using it:

• Incorrect settings (microphone is not set as default device)
  
• Corrupted or outdated driver
  
• Faulty device
  

For us to isolate the issue, we'd like to know the following:

• Were there any changes made to your computer prior to this issue(e.g. Windows updates)?
  
• Have you tried connecting other microphone to your computer?
  
• Have you tried connecting the microphone to the other computer?
  

In the meantime, we suggest running the Recording Audio Troubleshooter to find and repair problems with recording sound. We also suggest checking if your microphone is set as your default recording device. For troubleshooting steps, please see
Geethu B's on this
link.

We're looking forward to your reply.
