Why sound is not coming in my laptop

Let's take a look at what the issues might be. When laptop speakers are not working, it can be due to a problem with the sound settings or configuration, device drivers , or even physical defects in the speakers or wiring.

Here are the most common issues which may be behind your laptop speakers not working:. Some laptop speaker problems can be fixed at home without any special tools or expertise, and others require more in-depth diagnostics and repair work.

If you hear sound from your headphones, then there is either a problem with the software or driver responsible for switching outputs, or there is a physical problem with your laptop speakers.

Make sure the audio sensor isn't stuck. Laptops use a sensor to tell whether or not you have plugged headphones into the audio jack. If your computer thinks headphones are plugged in even when they aren't, it won't send sound to the speakers. Try plugging and unplugging your headphones and twisting the plug as you insert and remove it.

You may also be able to carefully trigger the sensor with a toothpick, but be aware physically breaking anything inside the jack may void your warranty.

If the problem is your audio input sensor, you will have to take your laptop in for service. Check your playback device.
