Windows volume setting. Always check to ensure that the volume on the media
player(s) has not been turned down or off.

adjust the volume, bass, or treble to eliminate distortion.

in the lower-right corner of your screen. Ensure that the volume is turned up and that
the sound is not muted.

front-panel headphone connector.
TEST THE ELECTRICAL OUTLET —Ensure that the electrical outlet is working by
testing it with another device, such as a lamp.
