You're not alone; I'm experiencing the same thing with AirPlay. I just got my 1021 and haven't gone through the full setup yet (waiting for my sub to arrive), but couldn't wait to try to stream from my iPhone. Once the music stops playing, I can change the speaker to my iPhone then back to the 1021 and it reconnects to the network and plays through my AVR, but that's not an acceptable solution. I'm hoping I just have a setting wrong somewhere. Just wanted you to know you're not the only one experiencing this. More later once I do a full setup and some troubleshooting.
I just got off the phone with Pioneer..... DUDE WAS THE BIGGEST PRICK I HAVE EVER TALKED TOO.
I told him that other people have this problem on a blog... he said... 'so what's your point.... where are you going with that'. LOL... can you believe that crap?
The only worthwhile thing he said was that there is nothing to do with the 'settings of the unit... it should work'. He said... "I got a problem". No Sh@t! Thanks. So.... don't rack your head against the wall trying to figure it out.... its a bad reciever. I'm returning this hunk. People.... always buy stuff from Best buy or a box store so you can return within 30 days.
