SYMPTOMS

When you put a CD-ROM in a CD-ROM drive that you usually use for data CDs, you may notice that the CD-ROM drive plays the sound files on that CD even though there is not an audio cable attached to that CD-ROM drive.

CAUSE

This behavior may occur if your sound card driver supports Digital Audio Extraction functionality.

WORKAROUND

To work around this behavior, disable the Digital CD Audio feature in the properties of the CD-ROM drive:
  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System, click the Device Manager tab, and then double-click CDROM to expand the branch.
  3. Click the CD-ROM drive, click Properties, and then click the Properties tab.
  4. Click to clear the Enable Digital CD Audio check box, click OK, and then click OK again to close the System Properties dialog box.

Steps to Reproduce the Problem

  1. Install 2 CD-ROM drives. Configure one with an audio cable, speakers, and so forth. Configure the other CD-ROM drive up to handle only data CDs.
  2. Install Millennium.
  3. Put an audio CD in the data CD-ROM drive and listen to the music.

Community Feedback System

Very often, it takes hours to solve a problem. Very often, you've looked high and low, and have tried a lot of solutions. When you finally found it, chances are, it was because someone else helped you. Here's your chance to give back. Use our community feedback tool to let others know what worked for you and what didn't.

Please also understand that the community feedback system is not warranted to be correct, it's simply a system that we've built to let people try and help each other. If something in a feedback response doesn't make sense to you, or you're not comfortable making changes that the feedback talks about (like registry edits), please consult a professional.
