themselves. An example is the Windows Media Player program. 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 even if I 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 I connect headphones to my computer while playing sound, a speaker does not
produce sound.
Solution: When the headphones are attached, the streaming is automatically redirected to it. If you want
to listen to sound from the speakers again, ensure that you set those speakers as the default device. For
more information, see the help information system for Realtek HD Audio Manager.
