Note: For details about controlling volume, refer to your Windows online help.
• 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
themselves. An example is the Windows Media Player. Usually the application has sliders available to
control the sound from within the program.
• 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 in the Volume Mixer window.
Solution : Use the hardware volume control. This is because the built-in synthesizer software does
not support the control.
• Problem : The sound cannot be turned off even if you set the Master volume control at minimum.
Solution : You still can 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 .
• Problem : When you connect a headphone to your computer while playing sound, a speaker does not
produce sound.
Solution : Once the headphone is attached, the streaming is automatically redirected to it. If you want
to listen to sound from the speakers again, be sure to set those speakers as the default device. The
procedure is as follows:
1. Go to Control Panel. Change the view of Control Panel from Category to Large icons or Small icons.
2. Click SmartAudio . The SmartAudio window opens.
3. Look at the playback devices. If you have attached a headphone, the headphone will be automatically
set as the default device, and the icon for that headphone will be checked.
4. To set a different device as the default, double-click the icon for those speakers. That icon will
now have a check mark.
5. Play any sound by use of a music program such as Windows Media Player. Make sure that sound
comes from the speakers.
For details, refer to the help information system for SmartAudio.
