I have pretty much the same problem. My Mac (7 days old) was working with the Apple TV just fine but tonight it will not do AirPlay nor will Apple TV play home share with the Mac either. Rebooting has no effect. Same error you are getting. When I try to play music (AirPlay) it is weak and intermittent at best and often simply does not play at all.
My ASUS laptop still works just fine as normal so Apple TV seems to be working just fine. Now I am wondering why I spent so much money on the Mac.

I have the same problem. The only fix seems to be to switch off and than on home sharing in iTunes. Which is annoying, because I have to go upstairs every time to do this.

I had this problem, but found out the reason it wasn't working was the Firewall on my Mac was set to block iTunes from connecting to my Mac from another system.
I put the settings to allow connection and it works great now.
