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.

•Reinstall the audio driver for your operating system.

•Check for interference: electrical appliances on the same circuit or operating in close proximity to the computer can cause interference.
