This chapter describes how to connect your computer system to external audio devices that use the 16-bit integrated audio controller on your computer’s system board.

The integrated Crystal 4237B controller is Sound Blaster Pro-compatible and supports the Windows Sound System. The 4237B controller has a Sound Retrieval System (SRS) 3D stereo digital signal processing (DSP) engine that retrieves and restores spa- cial sound information, directional cues, and other sonic nuances that are typically missing or are altered by electronic reproduction of stereo sound.

This chapter also describes the audio application programs that Dell has installed on your hard-disk drive, and it tells you how to reinstall audio drivers if necessary.

NOTE: The instructions in this chapter apply to systems using the integrated audio controller. If you are using a sound card, use the connection instructions in the docu- mentation that came with your sound card.
