Follow these steps in order on the new Windows 11 PC:

  1. Check microphone connection

    • If using a wired headset or mic, make sure it is firmly plugged into the correct audio jack or USB port.
    • If using Bluetooth, make sure the device is powered on and in pairing mode.

  2. Make sure Windows sees the microphone

    • Select Start > Settings > System > Sound.
    • Under Input, look for the microphone under Choose a device for speaking or recording.
      • If it appears, select it and use it as the default.
      • If it does not appear, continue with the next steps.

  3. Allow apps to use the microphone

    • Select Start > Settings > Privacy & security > Microphone.
    • Turn Microphone access On.
    • Turn Let apps access your microphone On and enable access for the apps that need it.
    • If using desktop apps (like Teams, Zoom, browsers), make sure Let desktop apps access your microphone is On.

  4. Set and test the microphone

    • Go to Start > Settings > System > Sound.
    • Under Input, select the microphone to use.
    • Select > to the right of the device to open Properties.
    • Under Input settings, select Start test and speak normally.
    • Select Stop test, then Play to hear the recording.
    • If volume is low, move the Input volume slider to the right.

  5. If others cannot hear anything

    • If the headset has a physical Mute button or switch, make sure it is not muted.
    • For Bluetooth headsets, confirm they are paired and connected.
    • In Settings > System > Sound, under Input, confirm the correct device is selected.
    • Run the Input devices troubleshooter under Troubleshoot common sound problems.

  6. If Windows says “no microphone found” or shows no input devices

    • Reinstall audio drivers:
      1. Right-click the Start button and select Device Manager.
      2. Expand Sound, video and game controllers.
      3. Right-click each audio device and select Uninstall device. Check Attempt to remove the driver for this device if available, then select Uninstall.
      4. Restart the PC. Windows will try to reinstall audio devices automatically.
      5. If nothing appears, open Device Manager again, right-click Sound, video and game controllers, and select Scan for hardware changes.
      6. After devices reappear, right-click the audio driver and select Update driver.

  7. Confirm the microphone is installed and test again

    • Go back to Start > Settings > System > Sound.
    • Under Input, confirm the microphone now appears.
    • Select it, open Properties (the > button), and use Start test / Play to verify it works.

If after these steps no input device appears at all, the issue is likely with the microphone hardware or the PC’s audio hardware and may require device manufacturer support.
