Sound and Speaker Problems
Basic Checks:
•
If using external speakers:
– Make sure that the speaker cables are firmly connected to the
computer.
– Test the electrical outlet: verify that the speakers are connected to
a working electrical outlet.
– Ensure that the speakers are turned on.
•
If using a sound card, make sure external audio devices are connected
to the sound card’s connectors and not to the microphone, line-out, or
line-in connectors on the computer's front or back panels.
•
Adjust the volume.
