Standard audio CD's? Did it work before? Has anyone been inside the computer lately. Have you checked all the volume properties to make sure the CD volume is not turned down or muted.<br><br>Double click the speaker icon in the tray to see the volume properties and make sure the CD volume is up and not muted.<br><br>If the computer has been opened recently then I would check the audio cable from the Cdrom drive to the audio card or motherboard...whichever is the case.<br><br>If all other sounds are working then the audio drivers, sound card, and resources should be Ok.<br><br>You may also want to go into the Multimedia applet in the Control Panel under devices....Media Control Devices/ CD Audio and make sure it is seleceted to use this device.<br><br><br>dxd
