Adjusting Sound Volume:
You can adjust sound volume by moving lever.
Also you can mute sound by pressing the
"mute button".
If there is only Line-in device plugged, UAJ will
remind you there is no any Line-out device
plugged in.
Note:
If you want to use AUX IN function, you must disable UAJ function from the Speaker Configuration
item in the AC97 Audio Configuation menu. After that, you'll have to use the Line-In volume lever
in the "Volume Control" menu to adjust the volume because AUX IN and Line-In functions are
controlled by the same audio signals.
