About The Speakers
Why is there no sound in any application?
❑ Check that the speakers are plugged into the Headphones jack.
❑ If your speakers have a mute button, verify that it is turned off.
❑ If your speakers are powered by batteries, verify that the batteries are
inserted properly and that they are charged.
❑ If your speakers use an external power source, verify that the power cord is
plugged into a grounded wall outlet or power strip.
❑ If your speakers have volume control, check the volume level.
❑ You cannot hear sound from your speakers if headphones are connected to
your computer.
❑ If the software application you are using has its own volume control, check
that the volume is turned up.
❑ Check the volume controls in the Windows® operating system using these
steps:
1 Click Start in the Windows taskbar, then select Control Panel.
2 Select Sounds, Speech, and Audio Devices, then click Adjust the
system volume.
3 From the Volume tab, adjust the Device volume by moving the slider
bar to the desired sound level. Verify that the Mute option is not
selected.
❑ Check that the Mute check box is not selected in the Windows volume
control.
✍ You may need to reinstall the sound drivers. See “Reinstalling device drivers using
Application Recovery CD(s)” for more information.
