12.1 PC Compatibles: Initial Installation

Symptoms
• No sound when running a
program
Possible Causes and Solutions
Application Does Not Use CD-Audio
There are two types of audio you may encounter when using CD-ROMs:
1) Sound Card Audio:
This comes from data (e.g., .WAV or .MID files) that is transferred from
your CD-ROM disc via the SCSI host adapter into your computer and
is translated by your sound board into sound. If you do not have a
sound board or USB speakers, you will not be able to hear this form
of audio.
2) CD-Audio:
This comes from audio discs (like the ones used by your home stereo)
that are translated directly by your CD-RW drive into sound. You do
not need a sound board to hear this audio. You can hear this audio by
plugging a set of headphones or powered speakers into the
headphone jack on the front of your drive.
One reason, then, that you might not hear sound when playing a CD-ROM
disc is that a sound board is required. These discs use only sound card audio,
not CD-Audio.
To help you determine if you are having a sound board problem or a
CD-Audio problem, try playing an audio CD in your CD-RW drive. If you can
hear music (through headphones or speakers connected to the headphone
jack on the front of your drive), the CD-ROM disc you are playing may require
the use of a sound board in order to hear sound. If possible, check the manual
that came with the CD-ROM disc and see if the use of a soundboard is
recommended or required.
