SYMPTOMS
When you insert a compact disc (CD) into a CD-ROM drive that you primarily use for data CDs, you may find that sound files are played and you can hear CD audio, even though an audio cable is not connected to your CD-ROM drive.



CAUSE
This behavior can occur if your sound card driver supports Digital Audio Extraction.



WORKAROUND
To work around this behavior, disable the digital audio playback feature of the CD-ROM drive. To do this, follow these steps:
 * 1) Click Start, click Control Panel, click Performance and Maintenance, and then click System.
 * 2) Click the Hardware tab, and then click Device Manager.
 * 3) Click the + (plus sign) next to DVD/CD-ROM drives, right-click your CD-ROM drive, and then click Properties.
 * 4) Click to clear the Enable digital CD audio for this CD-ROM device check box, and then click OK.
 * 5) On the File menu, click Exit to close the Device Manager window.
