[PROBLEM] Airplay is not working on XBIAN 1.0RC2 // XBMC 13.1

[MikeyT]

I have so nearly got this right! I am trying to AirPlay my iTunes collection from my iMac to a Raspberry Pi, which is connected to my TV via HDMI.

I am using Xbian kodi 14 helix RC3 on a Raspberry Pi Model B which is connected to my home network wirelessly. After zero success and much searching on the Internet, I have made these changes to the Pi:

allowed Audio pass-through
allowed AirPlay
changed a line in dbus.conf file to be: start on local-filesystems

When the Pi is online I can see xbian as an option in Sound in System Preferences on the iMac. If I HDMI connect the Pi to a monitor that has built-in speakers then I can play anything from iTunes and hear it in the monitor's speakers. However, when I set up the Pi with my TV, although it appears to be playing the iTunes music (there is a timer showing progress of the music) I get no sound. When I power down the Pi, the sound resumes from the iMac speakers.

I will continue to "play" with the settings on the TV and/or Pi and re-post if I get anywhere. if this has resonance for any of you out there - do let us all know!
