Microsoft warned that users could leave their platforms incapable of playing audio, “when uninstalling and reinstalling inbox audio driver repeatedly on Windows 7 or Windows Vista.” According to Microsoft “You use software to render/play audio via the DirectSound API (for example: DDK tool Graph Edit). On Vista or Windows 7, via a driver testing tool (or manually) you uninstall and then reinstall audio drivers such as "High Definition Audio Device" (HDAudio) several times. You attempt to render/play the audio stream again to a non-default DirectSound device (for example - DirectSound:Speakers as opposed to Default DirectSound device).” “To resolve, you can clean up internal store DirectSound uses to store audio device information. The store’ll be recreated when an application uses DirectSound again. Following keys and all subkeys can be safely removed to resolve the issue: HKEY_CURRENT_USER\Software\Microsoft\ActiveMovie | HKEY_CURRENT_USER\Software\Microsoft\Multimedia\ActiveMovie,” KB2011490.
