Now you’re ready to hear full-range stereo sound coming from the speakers and bass sound coming from the computer’s internal subwoofer.

To adjust the overall volume, use the sound control buttons on the front of the computer or use the Monitors & Sound control panel, which uses software inside your computer to adjust volume. (For more information, see “Adjusting Volume and Sound” in the previous section, “Using Your Computer’s Sound Features.”)

To adjust the subwoofer volume independently of the speaker volume, use the subwoofer balance control (Ï) on the back of the computer. (The subwoofer balance control works only when external speakers or a monitor with built-in speakers is attached.)
