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