Realtek is a computer hardware manufacturer that specializes in designing audio and network chips for computer manufacturers to use in their products. If you have a notebook computer running Windows, there is a good chance that the sound chip is designed by Realtek. If you have reinstalled Windows on your computer and find that it is unable to produce audio, you may not have the drivers for the Realtek sound chip installed. Obtain the drivers from the computer manufacturer or Realtek's website.
