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 applications are used.

Solution: It is normal for the sliders to change position when certain sound applications are used. The applications are aware of the Volume Mixer window (in Windows XP, Volume Control 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 application.

•Problem: The volume sliders do not all fit in the Volume Control window in Windows XP.

Solution: Press Ctrl+S keys while the volume control is in focus, and toggle to a smaller size.

•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 on the Volume Mixer window (in Windows XP, Volume Control window).

Solution: Use the hardware volume control. In Windows XP, use the hardware volume control or the Wave volume control on the Volume Control window. 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 Master volume control at minimum.

Solution: You can still 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 (in Windows Vista and Windows XP, Mute).

•Problem: Sound does not come from a headphone or a speaker, or your computer cannot record sounds when the SmartAudio is set to MULTI-STREAM mode (Windows Vista).

Solution: To switch from one device to another (for example, from a speaker to a headphone, or from an external microphone to a built-in microphone), do as follows:

1.Click Start ➙ Control Panel ➙ Hardware and Sound.

2.Click the SmartAudio icon. The SmartAudio window opens.

3.Make sure that you are in MULTI-STREAM mode in the Audio Director window.

4.In the Volume Mixer window, select the device you want-for example, speakers. If your computer is attached to a ThinkPad Mini Dock Plus or a ThinkPad Mini Dock, you can also select a device from them.

5.Play any sound via a music program (for example, Windows Media Player). Make sure that sound comes from speakers now.

6.Then, if you would like to switch to a headphone, close the music program.

7.Go to the Volume Mixer window. Then select another device, which is now the headphone.

8.Play any sound via the music program. Make sure that sound comes from a headphone attached directly to the system.

For details, refer to the Help for SmartAudio.

Note: In the Volume Mixer window of SmartAudio, a check mark by the entry for a device, such as speakers for a playback device, or a built-in microphone for a recording device, shows that the device has been selected.
