Most computers have a plug on the back of the CPU designated for
speakers and headphones. If you have configured your sound card, any
system or website sounds should play through the speakers or headphones.
Your CD-ROM probably has a plug near it as well, so you can listen to music CDs
through the CD-ROM drive. See the section called Playing CDs.
Regardless of how you choose to listen to music or other sounds, you
should remember that there may be other people working near you who
aren't interested in hearing your computer. Be courteous and keep the
volume down. Even headphones can "bleed" noise and disturb others.
Add the Mixer Applet ( =>

) to your panel so you can control system
volume. Click on the speaker icon in this applet to mute or activate
sound and use the slider bar to control volume level. Note that the
CD-ROM probably has its own volume control next to the CD drawer on
your computer.
