When you say, "Ok, for starters, any source you want piped through the AVR/Zone 2 will require stereo analog connections, digital alone won’t work." is that why my porch speakers sounded "muffled" when I piped the tv sound through them?
Fiber Optic from the AVR - 890 to the TV
If you meant with this connection, I’m surprised you heard anything.
Also, if I cannot attach an optical to my cd player (it's 18 years old) should I just use the regular rca cables? I'm guessing there would be no use for the optical then either, right?
Yes, the stereo RCAs work just fine.
I have the cd player because it's a multidisc player. Some of our dvd's don't play on the bluRay either, hence the sony dvd player. I could connect the bluRay with the other hdmi, right?
It’s kind of funny, in a sad way, but it makes sense. Yes, per my previous reply, you need 3-HDMI connections.
