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) which is transferred from
your CD-ROM disc, into your computer, and is translated by your sound-
board into sound. If you do not have a soundboard, you will not be able to
hear this form of audio.
2) CD Audio:
This comes from data that is translated directly by your CD-ROM drive into
sound. You do not need a soundboard to hear this audio. You can hear this
audio by plugging a set of headphones or powered speakers into the audio
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 soundboard is required. These discs use only sound card audio, not CD audio.
To help you determine if you are having a soundboard problem, or a CD Audio
problem, try playing a music CD in your CD-ROM drive. If you can hear music
(through headphones or speakers connected to the audio jack on the front of your
drive), the CD-ROM disc you had played may require the use of a soundboard 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.
If you have a soundboard, can hear a music CD when it is played, but cannot hear
sound when you play a CD-ROM disc, you may have configured your soundboard
incorrectly. Check the troubleshooting section of your soundboard manual for further
advice. If you have a soundboard but you cannot hear a music CD when it is played,
check the following points:
Improper/missing audio cable
If you use a soundboard, you must connect the soundboard to your CD-ROM drive
with an audio cable. See page 33 to ensure you have properly installed this audio
