Installing Sound/Audio Cards and Drivers
Sound or audio cards, whether it is a stand-alone device inserted into an expansion slot or embedded sound controllers in the motherboard, require specific device drivers in order to function and produce sound. This low-level program is responsible for processing the data between the sound card hardware and the operating system.
Most sound cards are bundled with the appropriate installation CD when purchased. This disc contains a database of the manufacturer’s available sound device drivers at the time of purchase and includes the specific driver intended for the card purchased. Most discs have an autorun installation program that prompts users to start installation. Some only provide a database of drivers and let the Device Manager or Add Hardware applications in the operation system perform the task of installation.
If you dont know the type of driver that you have, please check the following link to help you:
