Problem
: A volume or balance slider cannot be moved.
Solution
: The slider might be grayed out. This means that its position is fixed by the hardware and
cannot be changed.

Problem
: The volume sliders do not stay in place when some audio programs are used.
Solution
: It is normal for the sliders to change position when certain sound programs are used. The
programs are aware of the settings in the Volume Mixer window and are allowed to change the settings

control the sound from within the program.

Solution
: The control is designed to compensate for minor differences in balance and does not
completely mute either channel.

Solution

To turn off the sound completely, press the speaker mute button.
