Constants

DVFLAGS_ALLOWBACK
Enable the Back button on the wizard's Welcome page. If the user clicks the Back button on the Welcome page, the wizard exits, and CheckAudioSetup returns DVERR_USERBACK.
DVFLAGS_NOHOSTMIGRATE
The voice host will not migrate regardless of session and transport settings. Use this flag when you want to shut down the voice session completely.
DVFLAGS_QUERYONLY
Audio setup is not run. Instead, the method checks the registry to see if the devices have been tested. If the devices have not been tested, the method returns DVERR_RUNSETUP. If the devices have been tested, the method returns DV_FULLDUPLEX if the devices support full duplex audio, or DV_HALFDUPLEX if the devices do not support full duplex audio.
DVFLAGS_SYNC
Do not return until the operation is completed.
