The notification sound does not play in Communicator 2007 when you change the notification sound to a .wav file that resides in the Media folder

On a Windows XP-based client computer, you change the notification sound in Microsoft Office Communicator 2007 to a .wav file that resides in the %windir%\Media folder. However, the notification sound does not play in Communicator 2007.

Notes

• The .wav file plays if you change the notification sound to a .wav file that resides in any folder except the %windir%\Media folder.
• The %windir% placeholder specifies the path at which Windows is installed. Typically, C:\Windows is the path at which Windows is installed.

This problem occurs because the full path of the .wav file in the %windir%\Media folder is not written to the HKEY_CURRENT_USER\AppEvents\Schemes\Apps\Communicator\COMMUNICATOR_<event type>\.Current\(Default) registry key.

Communicator 2007 searches for .wav files only in the Communicator installation folder if no path is available in the registry.

This problem is fixed in the Communicator 2007 hotfix package that is dated December 17, 2007. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

To work around this problem, copy the .wav file from the %windir%\Media folder to any other folder on the client computer.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

You can change the notification sound in Communicator 2007 to a .wav file that resides in any folder except the %windir%\Media folder. This behavior occurs because the full path is written to the HKEY_CURRENT_USER\AppEvents\Schemes\Apps\Communicator\COMMUNICATOR_<event type>\.Current\(Default) registry key for folders other than the %windir%\Media folder. However, only the file name is written to the registry for the %windir%\Media folder. This is the default behavior in Windows XP because the %windir%\Media folder path is specified as the default media path in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MediaPath registry key.
