809 Won't get it either
It sound like a great excuse to move the 876 into the bedroom and upgrade to a TX-NR809.
809 Manual states that only analog can be routed to zone 2.
"Only analog input sources are output by the ZONE 2/3
PRE/LINE OUT and FRONT WIDE/ZONE 2 L/R terminals.
Digital input sources are not output. If no sound is heard when
an input source is selected, verify that the source is connected to
an analog input."
I've spent the last few hours looking for receivers that can send HMDI audio to zone 2 - I want to route the Pandora on my 'Smart TV' to speakers set up on my patio.
So far I have only found this badly needed feature/ability on big buck units and a few mid-line(and up) Pioneers. Yammy has a 'Party Mode' feature on some of their units that lets you play the same HDMI source on all speakers but you can't have one HDMI source in Zone 1 and another HDMI source in Zone 2 - to me that is 1/2 you know what
Have my hopes on a Pioneer VSX-1122 (list 600)
