Enabling a vocabulary via SAPI 4 interface with Dragon 64 bit edition fails with an invalid audio device error.


This may occur with SAPI 4 access to Dragon since audio devices are managed differently under Vista and Windows 7 and the default device settings may not be compatible.


Fixed in SpeechKit 6 build
