Yes, Tom.... I have an X4000. I had to go look because I didn't even remember.
Unfortunately, I can't be of any help unless I actually try an audio out. I don't use the Zones, so I don't really know anything about them. I also don't control it with a phone or iPad, nor do I generally access music off computers.
I'm sorry.... I just don't use it in any of the ways that you're looking to. I just bought it because I was tired of not having the higher-level audio soundtracks and enough HDMI inputs.
I HAVE listened to some music from my network, and that worked better / easier than my older Denon. And I'm willing to test something out for you. But I'm really not the guy to ask.
