Most generally, audio problems on laptops are not hardware issues to begin with, but problems with the software that controls the audio components. Check the ObviousBefore delving into repair solutions, there is the possibility you can't hear audio from your laptop due to basic settings that have been changed. Check the volume level. If your laptop has physical buttons to control audio, make sure the mute button is off and the volume is turned up. Check the volume control on your operating system to make sure the slider corresponds to your button settings. Physical buttons on your laptop may stop working for a number of reasons, so be sure to confirm your software audio settings using the audio controls found in your operating system. Also, make sure nothing is plugged into the headphone jack. Headphones or any other audio device plugged into the headphone jack will mute your laptop speakers. Reinstall the DriverA driver is a program that controls the hardware of your computer. Rule out file corruption of the audio device driver on your laptop by reinstalling the driver. This can be accomplished by locating the device in your operating system control panel and uninstalling the driver. When you reboot your computer, the operating system will search for available drivers for your audio device and install them. Upgrade the DriverHardware manufacturers for devices on your computer frequently update drivers to resolve issues discovered after the original drivers were released. These updates could contain fixes to the very problem you have encountered that prevents the audio device from working properly. Just as you located your audio device to re-install the driver, use the device manager in your operating system to identify the specific sound device used by your laptop. Go to that manufacturer's website and locate the latest driver for this device. Download the most recent driver release and install it on your computer. Check the Headphone JackThe most common point of failure in laptop audio hardware is the jack that connects your headphones or external speakers to your laptop. When this jack fails, it could mute the sound to your internal speakers as well, but more commonly it affects only the audio heard when you try to plug in your headphones. If you suspect the headphone jack is the problem, you should take your laptop to an authorized repair center for service. Depending on your model, you may have to replace a single inexpensive component or your entire computer main circuit board to remedy the problem.
