How to fix No Audio issue on my laptop

To troubleshoot the "No Audio" issue on your brother's laptop, consider the following steps:

1. Verify Audio Services: Make sure that the Windows Audio and Windows Audio Endpoint Builder services are running. You can do this by pressing Win + R, typing services.msc, and checking the status of these services.
2. Check Device Manager: Open Device Manager and look under "Sound, video and game controllers" to see if the audio device is present. If it shows a yellow exclamation mark, it indicates a driver issue. You can uninstall the device and restart the laptop to let Windows reinstall the driver automatically.
3. Install Driver Using PnPUtil: If you have the driver files, you can use the PnPUtil command to install them. Open an Administrator command prompt and execute the command: pnputil -i -a tabletaudiosample.inf (make sure to use the correct driver file).
4. Set Default Playback Device: Right-click the speaker icon in the taskbar, select "Playback devices," and ensure that the correct audio device is set as the default.
5. Try Different USB Ports: If you're using a USB audio device, try connecting it to a different USB port, as the issue might be related to the specific port.
6. Update Windows: Ensure that Windows is fully updated, as updates can include important fixes for audio issues.
7. Check for Driver Conflicts: If a device-specific driver was recently installed, it may conflict with the default USB audio driver. Uninstall the device-specific driver to see if that resolves the issue.

If these steps do not resolve the problem, consider referring to specific troubleshooting articles regarding USB audio devices or driver installation issues for more detailed guidance.

Hello,

I'm so sorry that you're having this problem. To fix the no-audio problem, you need to do more than what was already said. if you're still having problems You can also give this a shot.

First, run the built-in Windows Audio Troubleshooter. It may often find and correct common problems that simple tests don't find. To do this, right-click the speaker icon and choose "Troubleshoot sound problems." Next, you may check and fix any damaged Windows system files that might be causing audio problems by using the System File Checker (SFC) program. To do this, open Command Prompt as an administrator and type sfc /scannow. If none of the software options work, the problem is probably with the hardware. You may check this by connecting in headphones or external USB speakers. If these make sound, the laptop's internal speakers are broken and need to be fixed by a professional. Lastly, you might want to execute a System Restore to go back to a time when the audio was operating properly. This can undo modifications or conflicts that happened after you installed or updated something.
