There could be several reasons why you are not hearing any sound from your Windows laptop.
1. Check the Volume and Mute Settings: The first thing to do when you can’t hear any sound from your machine is to check the volume settings. Ensure that the volume bar is not at zero (which would mean that it is muted) or that the volume slider has been moved down. If it is, move the slider up and test whether any sound can now be heard.
2. Make Sure That the Speakers Are Turned On and Connected: If the volume settings are correct, then it may be that the speakers themselves are switched off or disconnected. Make sure that the power switch on the back of the speakers is switched on and that any cables connecting them to the laptop are properly connected.
3. Ensure That Your Sound Card Is Functioning: If the speakers have power and are connected, then it may be that the sound card itself has become faulty. To test this, go to “Control Panel” and select the “Sound” icon. On the top left side of the window, select the “Playback” tab. If there is a device that is highlighted in blue, then it indicates that the sound card is functioning correctly. If no device is listed here, then it indicates that either the sound card drivers need to be reinstalled, or that the sound card itself has become faulty.
4. Reinstall Audio Drivers: If the sound card appears to be working correctly, then it may be that the computer’s audio drivers need to be updated or reinstalled. In Windows 10, you can search for ‘Device Manager’ within the Cortana search box. Once in Device Manager, expand ‘Sound, video and game controllers’. Right-click the audio device, select ‘Update Driver Software’, then follow the on-screen instructions to complete the process.
5. Check Your Cables: If the above steps did not fix the issue, then it could be possible that the issue is being caused by either a faulty or broken cable. Make sure that any cables connected to the laptop such as headphones or an external speaker are in good condition. If the cable is broken, then replacing it should solve the issue.
6. Try a Different Pair of Speakers: If all of the above steps have failed, then it may be possible that the speakers themselves are faulty. Try connecting a different set of speakers to the laptop and testing if sound can now be heard. If sound can be heard when using a different set of speakers, then it could indicate that the original speakers may need to be replaced.
If none of the above steps help to resolve the problem, then it is likely that there may be a more serious issue with the laptop’s hardware. In this case, it is advisable to take the device to a certified technician who can diagnose and repair the issue.
