Possible Causes and Solutions
Application Does Not Use CD-Audio
There are two types of audio you may encounter when using CD-ROMs:
1) Soundcard 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 soundboard into sound. If you do not have a
soundboard 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-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
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 soundboard is required. These discs use only soundcard audio,
not CD-Audio.
To help you determine if you are having a soundboard problem or a CD-Audio
problem, try playing an audio CD in your CD-ROM 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 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.
