I turned off the HDMI passthrough feature and immediately had all six channels being decoded/passed to the receiver.
Would have been nice if Yamaha had mentioned that in the manual.
Oh well, live and learn.
BTW; It is a great receiver.
Thanks to all for the suggestions and advice.
Having the same issue I believe, where in the setup utility did you turn off the HDMI passthrough, cant seem to find it in the yamaha setup,
