CHAPTER 6: TROUBLESHOOTING
Speakers
There is no sound from the speakers
Ensure that subwoofer and the speakers are turned on:
See the documentation that shipped with your speakers. If your speakers have
volume controls, adjust the volume, bass, or treble to eliminate distortion.
Adjust the Windows volume control:
Click or double-click the speaker icon in the lower-right corner of your screen.
Ensure that the volume is turned up and that the sound is not muted.
Disconnect headphones from the headphone connector:
Sound from the speakers is automatically disabled when headphones are
connected to the headphone connector.
Test the power outlet:
Ensure that the power outlet is working by testing it with another device, such as
a lamp.
Reinstall the audio driver
Run PSA Diagnostics
NOTE: The volume control in some players overrides the Windows volume
setting. Ensure that you did not turn the player volume down or off.
Game Controllers
The computer does not recognize the game controller
Check if the cable connecting the game controller to the computer is not •
