It's all documented, but somewhat disappointing nonetheless. So you will have to double (HDMI+digital audio) or triple wire (HDMI+digital audio + analog 2ch audio) all the sources you want want to use for output and hope your source devices support simultaneous audio output for example HDMI and optical audio at the same time. I've done this and the end result works, but the amount of cable spaghetti I have behind my AV rack basically doubles due to this. In this sense the audio "processing" side of 5308 /AVC-A1HD is IMO quite unimpressive. Lack of pure HDMI passthough when using speakers connected to Denon is the biggest disappointment, this is available in some low end AVRs.
Thanks for the insight. I had a feeling I'd wind up having to double up on all the audio connections AND now the video as well. Of course, HDMI spec doesn't allow you to "down-convert" to component video, allowing the "Zone 2" component video output to display. So, if I want separate sources for my Main Zone and Zone 2, I need to run component video cables from each source. So much for a single neat cable for each source carrying both audio and video! 5 devices, 25 cables (3x5 component video, 5 HDMI, 5 TOS-link audio)!! Isn't that a pretty sight.
Add to that bi-wiring the fronts in a 9.2 main room. Talk about a spaghetti nightmare!
And to add insult to injury, Denon doesn't allow the 5308 to display the Zone 2 OSD on the component video output!
Just can't win.
