Using the Integrated Audio Controller: Dell Precision™ WorkStation 620 Systems
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
).

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.
