SYMPTOMS
After you upgrade from Microsoft Windows NT 4.0 with a legacy audio device installed, the sound card works but the legacy Windows NT 4.0 driver is still listed under Legacy Audio Drivers in Device Manager.



CAUSE
Setup does not correctly process the removal of legacy devices from the Wdmaudio.inf file. There should be no problem with the operation of the device even though the legacy device drivers are loaded.



RESOLUTION
To resolve this issue, manually remove the legacy device drivers from Device Manager.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
