Solution: The slider might be grayed out. This means that its position is xed by the hardware and
cannot be changed.
• Problem: The volume sliders do not stay in place when some audio applications are used.
Solution: It is normal for the sliders to change position when certain sound applications are used. The
applications are aware of the Volume Mixer window (in Windows XP, Volume Control window) and are
allowed to change the settings themselves. An example is the Windows Media Player. Usually the
application has sliders available to control the sound from within the application.
• Problem: The volume sliders do not all t in the Volume Control window in Windows XP.
Solution: Press Ctrl+S keys while the volume control is in focus, and toggle to a smaller size.
• Problem: The balance slider cannot completely mute one channel.
Solution: The control is designed to compensate for minor differences in balance and does not
completely mute either channel.
• Problem: There is no volume control for MIDI sound on the Volume Mixer window (in Windows XP,
Volume Control window).
Solution: Use the hardware volume control. In Windows XP, use the hardware volume control or the
Wave volume control on the Volume Control window. This is because the Built-In Synthesizer Software
does not support the control.
• Problem: The sound cannot be turned off completely even if you set the Master volume control at
minimum.
Solution: You can still hear some sound even though you have set the Master volume control at
minimum. To turn off the sound completely, go to the Master volume control and select Mute speakers
(Mute in Windows XP ).
