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 program 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 completely even if you set the Volume Mixer at minimum.

Solution: You still can hear some sound even though you have set the Volume Mixer at minimum. To turn off the sound completely, go to the Volume Mixer by clicking the speaker icon in the taskbar, then click Mixer. Click the Mute speaker icon.

•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. For details, refer to the help information system for Realtek HD Audio.
