Chapter 5: Customizing Your Computer’s Hardware Devices
Configuring the device driver for your mouse
All input devices, including mouse and trackball devices, have associated device driv-
ers that you can manage. To view or work with your input device’s driver, complete
the following steps:
1. In the Control Panel, click Hardware and Sound and then click Mouse.
2. On the Hardware tab, click Properties.
3. In the Mouse Properties dialog box, click the Driver tab.
4. Using the buttons provided, you can view driver details, update drivers, roll back
drivers, and uninstall drivers as necessary.
Optimizing Your Audio Settings
Most computers these days have sound cards as well as built-in, attached, or sepa-
rately connected speakers. Your computer may also have an audio input device such
as a microphone. Windows Vista handles sound a bit differently than its predeces-
sors. In Windows Vista, you can configure the computer’s main volume and the vol-
ume for running applications separately. By default, the volume level for running
applications is set relative to the main volume. Because of this, if you increase or
decrease the main volume, the volume of running applications is increased or
decreased as well relative to its initial value.
Controlling your computers master volume and application volume
You can control the master volume and application volume for your computer using
the following steps:
1. Click the Volume icon in the System Tray to display the Volume control.
2. With the Volume control displayed, you can adjust the main volume as neces-
sary and the volume of running applications will be adjusted as well.
3. To adjust the volume for running applications, click Mixer and then use the
Applications sliders to adjust the volume of running applications that have pro-
grammable audio input levels.
The main volume must always be at least as high as the application
volume. If you increase the volume of an application past the main
volume level, you will increase the main volume as well.
Setting audio playback levels
For more advanced control of audio devices, you can use the Sound utility. In the
Sound utility, playback and recording levels for sound are controlled separately. You
can set the output levels for audio playback by completing the following steps:

then click Configure. This displays the Speaker Setup Wizard.
3. On the Choose Your Configuration page, use the “Audio channels” list to select
the speaker setup that is most like your computer’s configuration. You can use
the options available as follows:
Mono
Select this option if your computer has a single speaker (or you want all your
speakers to be used as mono speakers).
Stereo
Select this option if your computer has one left speaker and one right
speaker.
Quadraphonic
Select this option if your computer has two pairs of speakers: front-left,
front-right, rear-left, and rear-right.
5.1 Surround
Select this option if your computer has surround sound with front-left,
front-right, rear-left, rear-right, and center speakers.
4. Test the configuration by clicking the Test button. Click any individual speaker
depicted to test its playback. Click Next when you are ready to continue.
5. If you previously selected 5.1 Surround, you’ll see the Customize Your Configu-
ration page next. As necessary, disable the center, subwoofer, rear speaker pair,
or any combination thereof by clearing the related checkboxes. Click any
speaker to test it. Click Next to continue.
