your computer, but each input can be
turned up or down individually by
adjusting the sound/mixer settings. To adjust
these settings, double-click the Volume icon on
the taskbar.
Your audio system may be muted. Press the Mute
button on the keyboard. If the message Mute Off

the keyboard. If they are, sound goes to the
