4. Connect earphones or headphones to the sound card’s Headphones
Jack. If there is no sound from your earphones or headphones, check
to see the CD audio cable is connected from the drive to the sound
card (refer to your sound card manual for more information). If the
audio cable is connected and there is still no sound from your ear-
phones or headphones, consult your dealer about your faulty card.
PROBLEM
Cannot detect the CD-ROM Drive (Windows 95 or Windows NT).
CAUSE
There are times when Windows cannot detect a new hardware.
SOLUTION Install the drivers manually.
• Start the Add New Hardware wizard by clicking My Com-
puter | Control Panel | Add New Hardware and then follow
the instructions on your screen.
NOTE: Let Windows detect your CD-ROM Drive. Make sure
you have installed and connected your CD-ROM Drive in your
computer before running the wizard.
PROBLEM
Cannot achieve the maximum data transfer rate performance speci-
fied for the CD-ROM Drive using benchmarking utilities.
CAUSE
Your CD-ROM Drive uses Constant Angular Velocity (CAV) tech-
nology, wherein the spindle motor is running at the same velocity,
while the drive is accessing data at the inner or outer tracks. In
this way, the CD-ROM will achieve lower data transfer rates at
the inner tracks and higher transfer rates at the outer tracks. Thus
using older benchmarking utilities, such as WinBench 96, will
give lower data transfer rates because these utilities use the drive’s
inner tracks for its performance tests.
SOLUTION Upgrade your benchmarking utility to one that supports tests on
the outer tracks of your drive, for example, WinBench 98.
PROBLEM
When playing a CD disc, there’s no image on the screen.
CAUSE
The disc may be an audio CD that does not have any screen im-
ages, or the disc may be defective.
SOLUTION Make sure the disc is not audio-only. To check if a disc is defec-
tive, examine it closely for deep scratches, pitting, or warping.
CD discs are covered with a hard coating that protects the disc,
but deep scratches, pitting, and warping can make a disc
unplayable.
