To enable or disable digital CD audio
Open Device Manager
Double-click DVD/CD-ROM drives, right-click the CD-ROM drive, and then click Properties.
On the Properties tab, select or clear the Enable digital CD audio for this CD-ROM device check box.
This check box enables some CD-ROM drives to digitally read the audio data from an audio CD, and send it to either a sound card or a pair of universal serial bus (USB) speakers. If you have USB speakers, you will be able to listen to CDs.
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
To open Device Manager, click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager.
You might need to restart your computer after changing this setting.
Enabling this feature can improve audio quality because Windows reads the CD directly, bypassing the CD-ROM drive's digital-to-analog converters. Directly accessing the CD improves quality because it eliminates extraneous electrical interference that can leak through the shielding on the cable that connects the CD-ROM drive to the sound card.
If you are not an administrator or a member of the Administrators group, you can use Run as to perform certain administrator functions. For more information on how to use Run as, see Related Topics.
