•

Problem

: I cannot move the volume slider or balance slider.

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 enabled to change the settings
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 Speaker/HP

•

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.

•

Problem

: Sound does not come from a headphone or a speaker, or the computer cannot record sounds.
