Realtek HD Audio Drivers is a tool that allows you to listen to audio in HD on your PC.

Drivers are generally lightweight software programs that communicate with your PC's operating system and other complimentary software in order to make a piece of hardware work.

In this instance, Realtek HD Audio Drivers communicate with the Windows 2000 or XP operating systems so you can listen to music from your speakers. They translate data into audio signals that allow speakers to play audio externally.

Realtek HD Audio Drivers can be centrally managed from your Windows Device Manager. To access your Windows 2000 or XP Device Manager, right click on My Computer while you're on the desktop. Either click the Properties tab or open the Control Panel and double click on the icon that says System. In the System Properties window, click on the tab that says Hardware. Once there, you can click the Device Manager button in order to access and manage Realtek HD Audio Drivers.

Alternatively, you can go to your Start Menu, click Settings, then Control Panel, double click the icon that says Systems, click on the tab that says Hardware in the System Properties window and then click the Device Manager button in the Hardware tab. Either path will allow you to manage Realtek HD Audio Drivers.

Realtek HD Audio Drivers can be a little tricky to access and manage, but these drivers will allow you to listen to audio in HD.
