    Hi Trish,

    I can see that the previous steps suggested by the Q&A Assist have already covered the essential checks. If the issue still persists after trying them, there are a few additional things you can try that are often helpful in this case:

    1. Restart Windows audio services

    Sometimes the audio service may stop responding during a call, which can make Windows behave as if no audio device is installed.

    -Press Win + R, type services.msc

    -Restart both Windows Audio and Windows Audio Endpoint Builder

    2. Perform a full power reset

    Hold the Power button for ~20 seconds until the device fully restarts This can reinitialize internal hardware (including audio components) if they temporarily stop responding.

    3.Test outside of Zoom

    Try using Voice Recorder or another app to confirm whether the microphone works at the system level. If it doesn’t show up there, the issue is likely at the Windows or driver level rather than Zoom.

    If the microphone still does not appear after these steps (for example, it no longer shows in Device Manager at all), please let me know what you’re seeing. In that case, it may require further driver or firmware-level troubleshooting.

    I hope this helps isolate the issue a bit more. Feel free to share what you find and we can continue from there.

    Use the following steps on the Surface Pro to restore the microphone and audio device.

    1. Check microphone privacy settings
      1. Select Start > Settings > Privacy > Microphone.
      2. Under Allow access to the microphone on this device, select Change and make sure the toggle is On.
      3. Make sure Allow apps to access your microphone is On.
      4. In Choose which Microsoft Store apps can access your microphone, ensure the toggle for Zoom (if listed as a Store app) or other calling apps is On.
    2. Make sure apps have access to the microphone (Windows 10/11)
      1. Select Start, then Settings > Privacy > Microphone.
      2. Turn on Allow apps to access your microphone.
      3. If using a classic desktop Zoom client, scroll down and make sure Allow desktop apps to access your microphone is set to On.
    3. Verify the correct input device and test the mic
      • On Windows 10:
        1. Select Start > Settings > System > Sound.
        2. Under Input, make sure the Surface internal microphone (or desired mic) is selected in Choose your input device.
        3. Speak into the mic and check Test your microphone to confirm Windows is receiving audio.
      • On Windows 11:
        1. Select Start > Settings > System > Sound.
        2. Under Input, go to Choose a device for speaking or recording and select the correct microphone.
        3. Select > next to the device, then use Start test under Microphone test, speak, then Stop test and Play the sample.
    4. Increase microphone volume (if very low or appears off)
      • On Windows 10:
        1. Go to Start > Settings > System > Sound.
        2. Under Input, select the microphone, then Device Properties.
        3. On the Levels tab, raise Microphone and Microphone Boost as needed, then select OK.
        4. Use Test your microphone again to confirm.
      • On Windows 11:
        1. Select Start > Settings > System > Sound.
        2. Under Input, select the microphone.
        3. Under Input settings, use Start test, speak normally, then Stop test and Play. Adjust the Input volume slider if needed.
    5. Run the built-in audio/microphone troubleshooters
      • Windows 10 Recording Audio troubleshooter:
        1. Select Settings > Update & Security > Troubleshoot > Additional troubleshooters.
        2. Select Recording Audio and run the troubleshooter.
      • Windows 11 sound troubleshooters:
        1. Select Start > Settings > System > Sound.
        2. Scroll to Advanced and choose Input devices under Troubleshoot common sound problems.
        3. Optionally select All sound devices under Advanced for more options.
    6. If Windows shows “no audio device” or does not detect the microphone at all
      1. Right-click Start and select Device Manager.
      2. Expand Sound, video and game controllers.
      3. For each audio device listed, right-click and select Uninstall device.
      4. Check Attempt to remove the driver for this device (or Delete the driver software for this device), then select Uninstall.
      5. Restart the Surface Pro. Windows will attempt to reinstall audio devices and drivers automatically.
      6. If nothing appears, open Device Manager again, right-click Sound, video and game controllers, and select Scan for hardware changes.
      7. After devices reappear, right-click the audio driver and select Update driver.
    7. If the microphone still does not appear
      • Confirm the internal mic is not disabled by privacy or sound settings as above.
      • If only external devices work, repeat the driver reinstall steps and recheck the Input device list.

    These steps typically restore the internal microphone and resolve “no audio device” symptoms on Surface devices after calls or driver changes.
