Retrieves the listener's velocity.
HRESULT GetVelocity( D3DVECTOR * pvVelocity );
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
Velocity is used only for calculating Doppler effect. It does not change the listener's position. To move the listener, use the IDirectSound3DListener8::SetPosition method.
The default velocity is (0,0,0).
