Use the built-in audio troubleshooters and then fix the “no audio device” / microphone issue with Device Manager.

1. Run the Recording Audio troubleshooter (for the microphone)
   1. Select Start > Settings > System > Sound.
   2. Scroll down to Advanced and under Troubleshoot common sound problems, choose Input devices.
   3. Select the microphone device if it appears, then run the troubleshooter and apply any fixes it suggests.
   If using the older layout (Windows 10 style):
   1. Select Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters.
   2. Select Recording Audio and run the troubleshooter.
2. Run the Playing Audio troubleshooter (for speakers)
   1. Go to Settings > System > Sound.
   2. Under Output, choose Troubleshoot (or Output devices under Troubleshoot common sound problems) and follow the steps.
3. Make sure the microphone and speakers are selected
   1. In Settings > System > Sound:
      • Under Output, ensure the internal speakers are selected.
      • Under Input, ensure the internal Realtek microphone is selected (if it appears).
   2. For the microphone, select the > next to the device, then use Start test under Microphone test and play back the Recorded sample.
4. If Windows reports “no audio device installed” or no Realtek device is listed
   1. Right-click Start and select Device Manager.
   2. Expand Sound, video and game controllers.
   3. If an audio device is present (e.g., Realtek):
      • Right-click it and select Uninstall device.
      • Check Delete the driver software for this device (or Attempt to remove the driver for this device), then select Uninstall.
   4. Restart the PC. Windows will attempt to reinstall the audio device and drivers automatically.
   5. If it does not reinstall:
      • Open Device Manager again.
      • Right-click Sound, video and game controllers and select Scan for hardware changes.
   6. After the device reappears, right-click the audio driver and select Update driver.
5. If the microphone is detected but very low or not working
   1. Go to Settings > System > Sound.
   2. Under Input, select the microphone.
   3. Use Start test / Stop test and adjust the Input volume slider (Windows 11), or open Device Properties → Levels and adjust Microphone and Microphone Boost (Windows 10).

If after these steps there is still no audio device listed at all, the issue may be with the hardware or OEM driver package and may require drivers from the PC manufacturer.
