To change the default speakers on your computer, first right-click the speaker icon on your taskbar and select “Sounds” from the menu that appears. In the “Sound” window, click the “Playback” tab. You can then click the “Default Speakers” drop-down list and select a different set of speakers to be used as your default. Note that you can also use the speaker icon in your system tray to quickly change your default speakers without opening the Sound window.
