User's Guide

Overview

This section describes how to connect your computer system to external audio devices that use the 32-bit integrated audio controller on your

computer's system board.

The integrated Crystal SoundFusion CS4614 Peripheral Component Interconnect (PCI) audio controller is Sound Blaster Pro-compatible and

supports Microsoft

DirectSound, DirectSound3D, and wavetable synthesis. The CS4614 controller has a Sound Retrieval System (SRS) 3D

stereo digital signal processing (DSP) engine that retrieves and restores spatial sound information, directional cues, and other sonic nuances that

are typically missing or are altered by electronic reproduction of stereo sound.

This section 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.

Connecting Audio Devices

You can connect a variety of audio devices to your computer. Use Figure 1 to locate the audio connectors on the input/output (I/O) panel on the

back of your computer.

Figure 1. Audio Connectors

Before you use any audio device, be sure that Sound in the System Setup program is set to On (the default).

Speakers

Your computer system supports most standard speakers that have integrated amplifiers. You can purchase speakers separately from Dell.

Connect the audio cable from the speakers to the audio line-out jack (see Figure 1).

NOTE: The instructions in this section apply to systems using the integrated audio controller. If you are using a sound card, use the

connection instructions in the documentation that came with your sound card.

Microphone jack

Audio line-out jack

Audio line-in jack

NOTES: The audio line-out jack has a mechanical switch that detects when external speakers are plugged in. If no external speakers

are plugged in, then all sound, including sounds from the operating system, is routed to the internal monophonic speaker. If external

speakers are plugged in, then all sound, including the PC beep, is routed through the audio line-out jack to the external speakers.

Sound is never routed to the internal speaker and external speakers simultaneously.

The Sound option in the System Setup program turns the audio controller on and off. When Sound is set to Off, neither the external

speakers nor the internal speaker produce sound.

The PC Speaker option in the System Setup program enables or disables the legacy PC beep. It does not turn the internal

monophonic speaker on or off. The basic input/output system (BIOS) beep codes are always audible regardless of this option setting.
