Given a mixer Device ID, you can obtain its corresponding device interface by
calling mixerMessage with DRV_QUERYDEVICEINTERFACE (and
DRV_QUERYDEVICEINTERFACESIZE). See the latest DDK under WDM Audio Extensions to
Legacy Windows Multimedia APIs for details. This should (hopefully) match with
one of the device interfaces you found from SetupDiEnumDeviceInterfaces.
