This article was previously published under Q105292 SYMPTOMS
When you play a .WAV file on a Sound Blaster 2.0 sound card (or a
compatible card, such as Media Concepts), repeating sounds may occur.
CAUSE
If the driver settings for the sound card are known to be correct but
.WAV sounds still repeat, the problem may be caused by a defective
parallel port card.
If the repeating sound occurs after the sound card has been used
several times, a defective parallel port card is a likely cause. With
a defective parallel card, the IRQ conflict arises because the
interrupt lines are locked by the defective card so that the
controller cannot correctly receive interrupt signals from the sound
card. Other peripherals (such as serial ports) may be affected as
well. The defect shows as an inability to properly use devices that
require interrupt control (for example, modems) under Windows 3.1.
NOTE: The interrupt settings on the parallel port card do not have to
be the same as the Sound Blaster settings for this problem to occur.
The defective parallel port card may or may not affect Sound Blaster
from an MS-DOS-based program.
The same repeating sound problem occurs when the sound card interrupt
setting and the interrupt chosen when setting up the sound card driver
in Windows 3.1 are not the same.
