of the Desktop screen.
Audio is hidden in Computer Setup. Enable the audio in Computer Setup: Security >
Device Security > System Audio.
The external speakers are not turned on. Turn on the external speakers.
The audio device may be connected to the wrong jack. Ensure that the device is connected to the correct jack on the
computer. The rear audio jack output is the green receptacle.
The speakers should be plugged into the line-out jack and
