About sound cards

Some IBM Aptiva PCs come with a sound card already installed.

Many software programs use the sound card for sound effects and music.  The
sound card works with the CD ROM drive to play audio compacts discs and to
process audio data files.

Most sound cards have the following connections:

Line in      This connector is designed to receive the output from another
             device such as a stereo receiver or tape recorder.

Mic          This connector is designed to receive input from an external
             microphone.

Line out     This connector is designed to transmit audio output from the
             sound card to another device such as amplified speakers, a
             stereo, tape recorder, or headphones.

MIDI         This connector is designed to receive or transmit MIDI
             (Musical Instrument Digital Interface) signals from devices
             such as a keyboard.  This connector may also be used with
             input devices for games such as a joystick.

If you need more information about the sound card that came installed in

NOTE:  The documentation that came with your sound card may either be
