Audio problems
• Problem: Wave or MIDI sound does not play correctly.
Solution: Make sure that the built-in audio device is configured correctly.
1. Go to Control Panel and click Hardware and Sound.
2. Click Device Manager. If you are prompted for an administrator password or confirmation, type the
password or provide confirmation.
3. Double-click Sound, video and game controllers. Make sure that the Dolby Advanced Audio
v2 driver is enabled and configured correctly.
• Problem: Recordings made using the microphone input are not loud enough.
Solution: Make sure that the Microphone Boost function is turned on and set by doing the following:
1. Go to Control Panel and click Hardware and Sound ➙ Sound.
2. Click the Recording tab in the Sound window.
3. Select Microphone, and click the Properties button.
4. Click the Levels tab, and move the Microphone Boost slider upwards.
5. Click OK.
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.
