SYMPTOMS
When you are playing Musical Instrument Digital Interface (MIDI) files in Windows Media Player, you may be unable to mute the playback. However, you may still be able to control the audio through the Volume Control tool.



CAUSE
As of July 2001, the DirectShow MIDI renderer (which uses the mixer Application Programming Interface) is used to control MIDI volume. The MIDI mixer is global, and because any program can control it, the program that used it last has control.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
