The most common audio frustration seems to be not being able to get any audio at all. Unfortunately, there are many sources of this problem, from the embarrassingly obvious to the most technically daunting. First, check your hardware: Make sure that you've correctly connected the speakers to the audio outputs of the computer and that you properly power up the entire set. Most external PC speakers require their own power source that you need to plug in and turn on. After power outages, for instance, when you turn your computer back on, your speakers may not power back up unless you do so manually. Also, make sure that you turn the speaker volume back up to audible levels. These may seem like painfully obvious solutions, but in our experiences we can trace back many “no sound” problems to the simplest oversights. Next, check to make sure that Windows recognizes your audio hardware. Click the Start menu, select Settings, and click Control Panel. In the Control Panel window, double-click the System icon. In the System Properties window, click the Hardware tab and then under Device Manager, click the Device Manager button. This window shows an outline of your hardware and the software drivers that make them work properly with Windows. Double-click Sound, Video And Game Controllers to check to make sure none of your audio devices has a red X on it. If you see a red X, this means that your computer recognizes the audio hardware, but the drivers are not properly installed. In this case, you’ll need to re-install your audio controller drivers.
