Verify the coordinate conventions expected by the spatializer and update orientation as well as position. Steam Audio's binaural effect takes a direction from listener to source and produces stereo output. Epic distinguishes headphone binaural rendering from loudspeaker panning. Test the actual output path rather than assuming that a stereo file and a binaural rendering path are interchangeable.
