I could resolve this after upgrade to 7.04 by setting the rear jack from "Rear Output" to "Mixed Output". Maybe this does also resolve it in previous releases. Seems to me it did work all along but the standard setting just doesn't playback Front and Center Audio Which is in most cases no sond. This also explains, why many hear only very silent Audio for the 3D Pre or Post Mixing will mix Front and Center Audio into Rear Output but at very low volume.
