Resolving sound issues
If you do not have sound from the speakers, try the following:
Check the volume and mute settings. See “Connecting Headphones.”
Use active (powered) speakers, or speakers with an amplifier.
Check the sound cable connections.
Ensure that the software program and sound software are properly configured.
Some software programs may result in low volume, even when the Volume is turned to the maximum value. If this is the case, click the Volume icon on the taskbar, and increase the system volume.
Reconfigure the sound software for surround sound.
Reinstall the audio card drivers by using application reinstallation program; refer to the Troubleshooting and Maintenance Guide that came with the computer.
