Sets the listener's orientation in terms of two vectors: a front vector and a top vector.
HRESULT SetOrientation( D3DVALUE xFront, D3DVALUE yFront, D3DVALUE zFront, D3DVALUE xTop, D3DVALUE yTop, D3DVALUE zTop, DWORD dwApply );
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
The front vector points in the direction of the listener's nose, and the top vector points out the top of the listener's head. By default, the front vector is (0,0,1.0) and the top vector is (0,1.0,0).
The top vector must be at right angles to the front vector. If necessary, DirectSound adjusts the front vector after setting the top vector.
