Make sure your speakers are correctly connected to your computer.
On your speakers, find the cable that plugs into your computer. Make sure that the speaker cable is plugged into the speakers and the correct jack on the computer. For example, if the cable is a 1/8 inch cable, there should be a round jack for it on the back of the computer. If it is a USB cable, it will plug into any USB port on your computer.
If the music in your library skips or the audio breaks up when you play it in Windows Media Player, there might be a problem with the audio driver installed on your computer. Typically, this type of problem only occurs toward the end of songs (in the last 20 seconds or so).
In some cases, you can work around the problem by disabling optional speaker effects that are collectively known as enhancements. If disabling speaker effects solves the problem, you might need to update your audio driver.
