WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, follow these steps: 
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Contro l\\Class\\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Contro l\\Class\\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.
