can only connect from old OS

[tbussmann]

When trying to connect from an iPad 2 with iOS 8.2 or iMac 10.9.5 (which hosts airsonos) the connection cannot be established. Verbose output underneath. When connecting from an iPhone 4S with iOS 6.1.3 (sic!) the connection is established and working fine. The version difference makes me believing Apple has changed a secret in the AirPlay protocol recently which airsonos (or the underlying libraries) do not support.

$ airsonos --version

this was an unsuccessful attempt to connect via the system control panel selecting the sound output device. I got a could not connect message. The log looks similar from iOS 8. An successful attempt from iOS 6 looks like following:

looking through other Tickets here I see similar Log entries but no explanation yet...

[tbussmann]

some more version / diag info:

$ brew info node
node: stable 0.12.1 (bottled), HEAD

$ airsonos --diagnostics
AirSonos Diagnostics
node version     v0.12.1
operating sys    darwin (x64)
ip address   192.168.178.23

from what I read in #113 may it be my node version is to new? What confuses me is that AirPlay is actually able to connect from iOS 6...

node 0.12 support will land with stephen/nodetunes#32
