No matter what speakers you have plugged in, Windows lets you adjust the master volume control. Depending on your sound card, you may adjust other options that enhance the sound as well. One example is the bass adjustment. You need to find out first if you can adjust the bass on your computer by exploring the possible areas where you can do so.
Load the “Volume Control” from the Start menu. Click the “Advanced” button and adjust the bass slider. This step only applies to Windows XP users.
Click the speaker icon on the notification tray (next to the taskbar clock) and click the “Mixer” link to load the “Volume Mixer”. Click on the speaker icon above the Master volume. Click the “Enhancements” tab and check the “Bass Boost" option. You can only perform this step if you are using Windows Vista or 7.
Go to the Control Panel and switch to the “Classic View” regardless of your Windows version. Look for any Control Panel icons that are linked to your sound card and double-click them. See if there are any special bass adjustment settings and adjust any sliders or check any boxes related to the bass. Some examples of these items are the SoundMAX and Realtek control panels.
