You may occasionally find that when you start Media Player, the Drivers menu no longer lists your CD Audio device. When you check your MPLAYER.INI file, you may find that the CD Audio line appears as "CD Audio=0" instead of "CD Audio=17". A zero in the [Devices] section of the MPLAYER.INI file indicates that the device is not available.


To correct the immediate problem, edit the MPLAYER.INI file in Notepad and replace the "0" on the CD Audio line with "17". When you restart Media Player, the CD Audio device will again be listed under the Device menu.

To find out why this problem occurs, you may need to do some troubleshooting with the following in mind.

  1. Media Player only writes changes to the MPLAYER.INI file in the following two situations:

    - A change has been made to the SYSTEM.INI file


    - You have installed a new WAVE, MIDI, or AUX driver using the Drivers section of the Windows Control Panel.
  2. If a device listed in the [MCI] section of SYSTEM.INI cannot be loaded while Media Player is writing to the MPLAYER.INI file, Media Player will set the parameter for that device to 0.
  3. Some reasons why the CD Audio device driver (MCICDA.DRV) might not be able to load include the following:

    - MSCDEX is not installed
    - Another application is using MCICDA.DRV
    - The CD-ROM driver is not installed
    - The SCSI bus for the CD-ROM drive may be locking up
    - Media Player may have problems loading MCICDA.DRV while other
    applications are communicating with the CD-ROM driver
  4. Some CD-ROM controllers are known to randomly lock the SCSI bus for no apparent reason, but work fine after you turn off your computer and then restart it. This problem has been found to occur with some older Media Vision boards.
