Typically, when using analog preouts for Zone 2/3, the input has to be analog as well (which is probably why the CD player works).
Typically, when using HDMI out for Zone 2/3, the input has to be HDMI as well (so I'm surprised that the AppleTV doesn't work).
Streaming content is considered digital, so may not send out over analog preouts
Typically, higher end systems like the LX801 do analog/digital conversion so any input can be sent to Zone 2/3 over any port. That doesn't seem to be happening though.
Hopefully opideegs' references to the manual will help clarify.
If you're trying to play streaming music like Pandora, Spotify, Tidal, etc to the other Zone/receiver, you may not need to use the Zone features.
If the 2nd receiver isn't already Play-Fi compatible, you could add a Play-Fi streamer like the inexpensive Phorus PR5 to the other receiver.
Then you can use the Play-Fi app to send streaming music to one or both, independently or grouped.

The only way I can send music through Zone 2 is when the source is a CD player, and not when it's either Apple TV or direct to Airplay. I was once told it's because the source has to be digital, is that correct? I also just today tried the HDMI out from the LX801 to the HDMI in of the other receiver, but that doesn't work either. If that truly is the case it seems a little odd, and to me defeats the purpose a bit of having a Zone 2. Does anybody have any knowledge on this? Thank you!!
