Speakers and sound
Symptom Possible solution
Volume is very
low or
unsatisfactory.
Ensure that you connected the speakers to the Audio Out (lime green) connector on the back
of the computer. (Additional audio connectors are used for multiple-channel speakers.)
Detached non-powered speakers (speakers without a separate power source, such as
batteries or a power cord) do not produce satisfactory sound. Replace the non-powered
speakers with powered speakers.
No sound is
produced.
For Windows 7:
1. Click Start, click Control Panel, click Action Center, and then click Troubleshooting.
2. Under Hardware and Sound, click Troubleshoot and audio playback.
If you use an High-Definition Multimedia Interface (HDMI) connector on the graphics card
(select models only) to connect your monitor to the computer, you should also connect
analog speakers to the computer Audio Line Out connector if you want to hear sound during
the initial setup of the computer. Refer to the Setup Poster to connect analog speakers.
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 on-screen display (OSD) and ensure
that audio is enabled and that the volume is set appropriately.
Ensure that you connected powered (active) speakers and that they are turned on.
Turn off your computer, and then unplug and reconnect the speakers. Ensure that the
speakers are connected to an audio connector, not a Line In or headphone connector.
To resume from Sleep mode, press the Sleep button (select models only), or press Esc.
Unplug headphones if they are connected to your computer (or speaker system).
