than beep codes), but any attached external speakers do transmit these sounds. For more information, see "Sound" and "PC Speaker".

Microphones

Your computer system supports most standard personal computer microphones. You can purchase a microphone separately from Dell.

Connect the audio cable from the microphone to the microphone jack (see Figure 6-1).

Record/Playback Devices

Your computer system supports a variety of record/playback devices such as cassette players, CD players, radios, stereo systems, video cassette recorders (VCRs), and tape players.

Connect the line-out cable from any one of these devices to the line-in jack on the back of your computer (see Figure 6-1).

CD-ROM Drives

To use an internal CD-ROM drive with the integrated audio controller, do the following:

1.Install the CD-ROM drive in your computer.

For instructions on installing a CD-ROM drive that uses the computer's enhanced integrated drive electronics (EIDE) interface, see "Installing a Drive in a 5.25-Inch Drive Bay".

For instructions on installing a small computer system interface (SCSI) CD-ROM drive, see "Installing SCSI Devices".

2.Connect the audio cable from the CD-ROM drive to the CD-ROM drive audio interface connector (labeled "CD-IN") on the system board.

See Figure 9-1 for the location of the CD-IN connector on the system board.

NOTES: The integrated audio controller allows you to manipulate musical instrument digital interface (MIDI) files on your computer and to hear output from those files on external speakers. However, to communicate with an external MIDI device, such as a synthesizer or other musical instrument, you must install a MIDI-compatible expansion card. (For instructions, see "Installing an Expansion Card".) If you use a MIDI card, set Sound in the System Setup program to Off. (See "Using the System Setup Program" for information on changing System Setup settings.)

To use a joystick, install a joystick-compatible expansion card in your computer. (For instructions, see "Installing an Expansion Card".) If you use a joystick card with sound capabilities, set Sound in the System Setup program to Off. (See "Using the System Setup Program" for information on changing System Setup settings.)
