Thanks, Eric. That is interesting. Onkyo RZ support did tell me what I reported. I am trying to use the zone 2 line outs (not the pre-out, I think). I am using the regular speaker wire outs to zone 2 that one can also use for height speakers with a 7.1.2 configuration. I obviously have a 7.1 with zone 2 configuration. I have no separate amp for zone 2 (if this makes sense). Do I have something configured or connected wrong. I am doing this per the manual, which I downloaded. If the amp is supposed to have a digital to analog converter to zone 2, it must not be working with the connection and configuration I have. Should I be calling Onkyo again?
So far I only seem to be able to select Source on zone 2. Zone 2 should be able to play a different input than Main, but I either have not gotten this to work, or not figured it out yet. Onkyo also had no explanation for why I heard nothing from the zone 2 speakers during the multi-zone test when I redid the initial setup.
Okay, called Onkyo again: told me the same info. To get zone 2 to work with HDMI input, the input device needs to be set to PCM. This will downgrade the audio signal for the main speakers too, apparently. I don't want to do this (and I don't use zone 2 for the DVR anyway, or when watching Blue Ray movies). So the old LG player mentioned below which has analog outs (which I can use as a dedicated CD player) is a better work around.
I do happen to have an older LG DVD/Blue Ray player that had stopped working for DVDs some time ago (and which I replaced). It's been sitting around, and I tested it, and it will still play CDs and using the analog outputs for it, I can send sound to the zone 2 speakers. It is low profile physically, so it will fit in the cabinet easily. But if there is something I'm missing on the amp, I'd sure love to know.
One other note: the interface on the amp itself (controls) are much less user friendly than on the 606 for zone 2. The 606 had dedicated volume buttons for zone 2. The 603 does not, and also when playing music through main and zone 2, and then turning off the amp, it turns off only the main speakers. Seems one has to set the remote control to zone 2 to turn them off... nuts. Doesn't seem to be an easy way to do this on the amp itself.
