Update Your Drivers

Since this problem is usually caused by incompatible/incorrect/faulty/outdated drivers, we suggest you to update your audio and video drivers first. A graphics (video) driver is the software that allows your operating system and programs to use your computer graphics hardware. Updated graphics drivers are important and often deliver better performance. Driver updates typically provide bug fixes and compatibility. Most drivers that come with your computer or Windows (through Windows Update) are good enough, and there is no need to install or update other drivers. There is, however, an exception for graphic drivers.

The audio driver is the part of the computer’s system that takes the signals originating from the program and turns them into the format in which they can be used on speakers (or other audio devices). This allows the sound card to facilitate audio output from the computer and communicate with the speaker.

So, try to install the latest drivers (update them). You can simply go to your audio and video cards manufacturer's web page, download & install the latest drivers for your hardware from there. Or you can do this manually by using Device Manager on your Windows, or automatically by using Driver Easy software.

To update your audio and video drivers manually go to Device Manager. You can access Device Manager by typing "device manager" in Search and clicking on the Device Manager result.

update your drivers step 1
