Hi, I'm Bernard. I'm happy to help!
To confirm, is this a built-in laptop microphone or an external Microphone? Have you noticed any changes before the issue started? And have you installed any hardware or software that may trigger the issue?
While waiting, I recommend running the Audio Troubleshooter and rolling back the driver first to check if there are any incompatibility issues. Kindly follow the steps below:
Method 1. Run the Audio Troubleshooter:
Press the Windows Key + R, then type in:
msdt.exe /id AudioPlaybackDiagnostic
Then hit OK and follow the prompts to run the Audio Troubleshooter.
Method 2. Roll back the Microphone driver:
-Press the Windows key + X
-Go to Device Manager
-Expand the Audio inputs and Outputs
-Look for your Microphone
-Right-click and click Update Driver
-Select Browse my computer for drivers
-Click Let me pick from a list of available drivers on my computer
-Choose an old driver or another driver name, then select it and hit Next until it installs.
Method 3. Roll back the audio driver:
-Press the Windows key + X
-Go to Device Manager
-Expand Sound, video and game controllers
-Look for Realtek (R) Audio or High Definition Audio
-Right-click and click Update Driver
-Select Browse my computer for drivers
-Click Let me pick from a list of available drivers on my computer
-Choose an old driver or another driver name, then select it and hit Next until it installs.
Note: If the issue persists, please download and install a Microphone and Audio driver from your manufacturer's website.
