Solving Audio Problems

If the computer has audio features and you encounter audio problems, see the common causes and

solutions listed in the following table.

Sound does not come out of the speaker or headphones.

Cause Solution

Software volume control is turned down or muted.

The keyboard Mute button has been pressed.

Monitor volume control is turned down on built-in speakers.

The powered external speakers are not turned on.

The audio device may be connected to the wrong jack.

External speakers plugged into the wrong audio jack on a

recently installed sound card.

Audio is disabled in Computer Setup.

Digital CD audio is not enabled.

Headphones or devices connected to the line-out connector

mute the internal speaker.

Computer is in

standby

mode.

Headphones are overriding the speakers

Some applications can select which audio output device is

used.

The operating system controls may be set to use a different

audio device as the default output device than what is

expected.

Double-click the

Speaker

icon on the taskbar, then make

sure that

Mute

is not selected and use the volume slider to

adjust the volume.

Press the Mute button on the keyboard to see if the Mute

feature is turned on.

If you are using built-in monitor speakers, use the monitor front

panel Volume button to adjust volume. Use the front panel

buttons to enter the onscreen display (OSD) and ensure that

audio is enabled and that the volume is set appropriately.

Ensure powered (active) speakers are turned on. Active

speakers have a power cord or batteries. Speakers are sold

separately.

Ensure that the device is connected to the correct jack on the

computer. The speakers should be plugged into the rear lineout

jack and the headphones should be plugged into the front

headphone jack.

See the sound card documentation for proper speaker

connection.

Run the Computer Setup utility and enable the audio.

Enable digital CD audio. In the Device Manager, right-click on

the CD/DVD device and select

Properties

. Make sure

Enable digital CD audio for this CD-ROM device

checked.

Turn on and use headphones or external speakers, if

connected, or disconnect headphones or external speakers.

Press the power button to resume from

standby

mode.

CAUTION:

When attempting to resume from

standby

mode, do not hold down the power button for more than four

seconds. Otherwise, the computer will shut down and you will

lose any unsaved data.

Unplug the headphones from the computer to allow audio to

flow through the speakers.

Make sure the application has selected the correct audio

device.

Set the operating system to use the correct audio device.
