4 Turn on the audio source, then adjust the volume to a comfortable level.
Troubleshooting
Checking your sound source
You may believe that the speakers are not working, when, in fact, the
sound source may be the problem. When connecting to a computer,
the most common problem is an incorrect connection. Make sure
that you are connected to the audio output jack from your computer
sound card (usually green). Also, make sure that your CD or DVD drive
is playing and the volume settings are turned up and not muted. If
you still have problems, disconnect the speaker source cable from
your computer and connect it to any device with a mini headphone
jack, such as a digital music player. If your speakers work on the other
source, the speakers are functioning correctly and the problem is in
your computer or the connections.
