1] Basic Troubleshooting to fix the Microphone

Restart PC

Try restarting your PC, as this simple step sometimes solves most issues in Windows.

  • Is your Microphone connected to the PC?

    Check whether the microphone you are using is connected to the PC. Select Start > Settings > System > Sound. In Sound settings, check on your connected microphones. Ifit is a Bluetooth microphone, select Add device next to Pair a new Bluetooth device. Bluetooth devices are known to disconnect after being idle, which can be the case here.

  • Check Microphone access to apps and Windows (Privacy Settings):

    Select Start > Settings > Privacy & security > Microphone. Next, go to Let apps access your microphone. Once you have allowed microphone access to your apps, you can change the settings for each app.

  • Check if you have access to Mic in the app:

    It will vary from application to application. If you are facing an issue in an app, go to the app’s settings and then locate the audio and microphone settings. Check if the correct microphone is selected.

  • Check Volume Bar:

    Make sure your microphone is connected to your PC. Select Start > Settings > System > Sound. In Sound settings, go to Input and, next to Volume, look for the blue bar that rises and falls as you speak into your microphone.

    Alternatively, you can also use the sound recorder in Windows to check if you can hear anything once you record the audio. If you can see waves as you speak on the sound recorder, it’s a sign that the microphone is working.

  • Use System Restore:

    You will need admin permission to ensure a system restore is in place. If the drivers cause an issue, you can always restore the PC to the previous state.

    If the problem persists after performing the basic troubleshooting, follow the advanced troubleshooting guide to solve the problem of the Realtek Microphone not working on Windows.

    If the microphone still doesn’t work?
