    Hi,

    1. What is the make and model of your device?

    In the search bar, type MSINFO32 and hit Enter.

    Please share a screenshot of that window.

    1. Are you using a built-in Microphone or external one connected via Bluetooth, USB, or Jack?

    In the meantime, please try the following:

    Press the Windows key + R, type mmsys.cpl, and click OK.

    Go to the Recording tab.

    Right-click the microphone and select Enable.

    Right-click it again and choose Set as Default Device.

    Right-click the microphone once more and select Properties.

    In the Levels tab, adjust the volume slider to the maximum value, then click OK.

    Next, go to the Advanced tab and uncheck the box that says 'Allow applications to take exclusive control of this device.'

    Try these steps in order on Windows 11/10 to restore the missing input device:

    1. Check the physical mic/headset
      • If using a wired or USB headset/mic, unplug it and plug it back in firmly.
      • If using Bluetooth, make sure it is paired and connected.
    2. Make sure apps are allowed to use the microphone (Windows 10)
      1. Select Start > Settings > Privacy > Microphone.
      2. Select Change, then turn on Allow apps to access your microphone.
      3. Under Choose which Microsoft Store apps can access your microphone, turn on access for the apps needed (for example, Zoom if installed from Microsoft Store).
      4. Ensure Allow desktop apps to access your microphone is set to On.
    3. Confirm the correct input device and test it
      • Windows 11:
        1. Select Start > Settings > System > Sound.
        2. In Input, go to Choose a device for speaking or recording and select the microphone or headset to use.
        3. Select > to the right of the device. On the properties page, select Start test under Microphone test and speak into the microphone. Select Stop test and choose Play under Recorded sample to hear what it sounds like.
      • Windows 10:
        1. Select Start, then Settings > System > Sound.
        2. In Input, ensure the microphone is selected under Choose your input device.
        3. Speak into the mic and check Test your microphone to confirm Windows is hearing audio.
    4. If no input device appears at all, reinstall audio drivers
      1. Right-click the Start button and select Device Manager.
      2. Expand Sound, video and game controllers.
      3. For each audio device listed, right-click and select Uninstall device.
        • If shown, check Attempt to remove the driver for this device or Delete the driver software for this device, then select Uninstall.
      4. Restart the PC. Windows will attempt to reinstall audio devices and drivers 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.
    5. Run the Recording Audio troubleshooter
      • Windows 11:
        1. Select Settings > System > Sound.
        2. Scroll down to Advanced and choose Input devices under Troubleshoot common sound problems.
        3. Use All sound devices under Advanced for additional options.
      • Windows 10:
        1. Select Settings > Update & Security > Troubleshoot > Additional troubleshooters.
        2. Select the Recording Audio troubleshooter and follow the prompts.

    If after these steps there is still “No input devices found,” install the latest audio drivers from the PC or motherboard manufacturer’s support site, then reboot and recheck Settings > System > Sound.
