The problem is act doesn't contain focalpoint or inst. I don't know off the top of my head but I believe focalpoint is similar to cameras and requires finding parent or child of act.doer which is inst. Usually I think sound emitters are called in states not actions as it is easier to control the timing and link to the sound emitter.
