SYMPTOMS
If a user leaves an audio-enabled program running, and then a subsequent user profile is accessed by means of the Fast User Switching feature, the audio may be heard in the newly logged-on profile even though the program is being run under the initial-user profile.

NOTE: The expected behavior is for the audio to be heard only from the programs that are being run by the currently logged user profile.



CAUSE
This behavior can occur because many programs can have difficulty with the Fast User Switching feature. Most programs have been designed for single users on a single computer, and these programs do not know how to respond to a Windows notification that a fast user switch is about to occur.



RESOLUTION
To resolve this behavior, either upgrade the programs, if applicable, or stop the sound-emitting program before switching users.
