SYMPTOMS
When you restart your Windows XP-based or your Windows 2000-based system, the volume levels on your audio mixer may be reset to their default settings.



CAUSE
This issue occurs if a line associated with the mixer device is not read correctly during the initialization process. This scenario causes one of the following:
 * The line is not added to the current list of lines, which causes a disparity between the current count in the list and the number of lines listed in the registry.
 * Even if the line is added to the list, the information loaded into the node may differ from the information stored in the registry. When these types of disparities occur, the operating system recognizes the mixer device as a different device, and it treats the initialized device as a new device. Therefore, the associated mixer registry key is deleted, and a new mixer registry key is created from the list built during the initialization process.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
