When you run an application that uses audio recording or playback functionality in Windows Vista, you may receive an error message that states that a file or a Microsoft Windows component is missing or could not be started.

For example, when you click Mixer in Windows Media Encoder 9, you receive the following error message:

The mixer application ’sndvol32.exe’ could not be started.
The system cannot find the file specified. (0×80070002)

Note: The specific error message that you receive depends on the application.
