    Since restart did not help and Windows shows no input or output device, use this order:

    1. Check the selected output device
      • Select the Speakers icon on the taskbar.
      • Select the arrow to open the list of audio devices.
      • If a speaker, headphones, or monitor audio device appears, select the correct one.
    2. Check hardware and volume
      • Make sure speakers or headphones are fully connected.
      • If using USB audio, try a different USB port.
      • If using a 3.5 mm jack, make sure it is in the correct port.
      • Make sure mute is off and volume is turned up in both Windows and the app.
      • Unplug headphones if they are connected, because some systems disable speakers while headphones are plugged in.
    3. Check whether the audio device is disabled
      • In Windows 10: right-click the Speakers icon on the taskbar and select Open Volume mixer.
      • Make sure the device is not muted.
      • Go to Start > Settings > System > Sound.
      • Select the audio device, then Device properties.
      • Make sure Disable is not selected for both output and input devices.
    4. Set the default audio device
      • In Windows 11: Start > Settings > System > Sound.
      • In the Output section, select the device to use. This also sets it as default.
      • If using USB or HDMI audio, this step is especially important.
    5. Turn off audio enhancements
      • Go to Start > Settings > Sound.
      • In Output, select the device in use.
      • Under Advanced settings, set Audio enhancements to Off.
    6. Run the audio troubleshooter
      • Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
      • Under Audio, select Run.
    7. Install Windows updates
      • In Windows 11: Start > Settings > Windows Update > Check for updates.
      • Install available updates and restart.
      • In Windows 10: Start > Settings > Update & Security > Windows Update > Check for updates.
    8. Update or reinstall the audio driver
      • Open Device Manager.
      • Expand Sound, video and game controllers.
      • Right-click the sound device and select Update driver > Search automatically for drivers.
      • If that does not help, right-click the same device and select Uninstall device.
      • If prompted, select the checkbox to remove/delete the driver.
      • Warning: save open schoolwork before restarting.
      • Restart the laptop so Windows reinstalls the driver automatically.
    9. If sound stopped after Windows Update, roll back the driver
      • In Device Manager, right-click the sound device > Properties > Driver tab > Roll Back Driver.

    If Sound, video and game controllers is missing entirely in Device Manager, or no audio device appears after reinstalling the driver, install the latest audio driver from the laptop manufacturer’s support site for that exact model.

    The battery draining quickly when unplugged is a separate hardware or battery issue and is not part of the Windows audio troubleshooting steps.
