MXDM_INIT (Windows CE 5.0)
A user-mode mixer driver's mxdMessage function receives a MXDM_INIT message while the driver is being installed.
typedef struct { DWORD uDeviceId; UINT uMsg; DWORD dwUser; DWORD lParam1; DWORD lParam2;} MXDM_INIT;

Return Values
Returns MMSYSERR_NOERROR if the operation is successful. Otherwise, it returns one of the MMSYSERR or MIXERR error codes defined in Mmsystem.h.
