Speakers do not work but rearly they will?

What type computer? Vista or XP? I take it you have X-530 speakers?

Go to control panel,and check device manager to see if you have any problems. If not, click on Hardware and Sound, then on Sound, and you will see the "Playback" tab. Highlight "speakers" by clicking on it, then click on "configure" to see how your laptop speakers are configured. If you have a laptop, your internal laptop speakers should be turned off. Configure them for your external speakers and test the sound there. If you need to use your laptop speakers (say you take your laptop somewhere without your external speakers) you will need to reconfigure your sound to the laptop speakers. Let me know if you have further problems--you may need to update your sound driver.

Have you done maintenance on your computer, such as getting rid of unnecessary files and defragmenting the hard drive? If not, go to "applications" in your program files to do so.
