Troubleshooting Sound
Sound and sound cards have advanced tremendously since
the early days. Unfortunately, the problems and conflicts are
still about the same. Following are common problems and
possible solutions.
• IRQ (interrupt request) problems. Typically, you move the
mouse and sound turns off. The sound card can use two
or three IRQs. This isn’t a problem on OS’s, such as XP,
which have almost unlimited IRQs or IRQ sharing. You
can sometimes alleviate an IRQ problem by assigning other
IRQs in the Device Manager.
• The overloaded system doesn’t have enough memory
• The sound channel has already been taken (allocated)
by another application that’s playing sound. Check in
Task Manager.
• Using utilities such as XP Sound Troubleshooter or
Mplayer2, you may be able to address the following
common situations:
1. You don’t hear sound coming from your
computer’s speakers or headphones.
2. A sound seems to be playing, but you don’t
hear anything.
3. A sound is playing but stops suddenly.
4. A sound skips or misses in some areas.
5. A sound is distorted or scratchy.
6. The computer stops responding (hangs) when
a sound is played.
7. The computer automatically restarts when a
sound is played.
8. You receive an error message on the screen
when you attempt to play sound.
• For Windows Vista and Windows 7, if you have an Internet
connection, connect to the following URL and use the
online Sound playback Troubleshooter:
• Make sure the sound cards are seated properly and that
sound cables are connected (such as from the CD-ROM
drive). Also, make sure that cables match their appropriate
• Make sure onboard sound is working. If it isn’t, turn it
off in CMOS and add a sound card. Maybe the onboard
sound works fine, but you want to add a newer, better
card; onboard sound must be disabled before the installed
sound card can work.
• Verify that the right driver has been installed. If not,
• Static or choppy sound may be the result of the video
card taking most of the bus resources (PCI sharing).
