airplay randomly kicking in
Hi.
I have a yamaha amp for surround duties which has airplay built in, handy on the very rare occasions I want it.
however when trying to play music from my mini into my main hifi via optical it sometimes randomly decides its going to play from airplay.
This is an issue accross my devices, I think osx for what ever reason in a split second cannot find or use optical so decides to default to airplay.
I absolutley want this behaviour to stop, for me it should be a simple case of disabling airplay in OSX, but cannot find any method to do so, is there like a terminal command or something to make OSX ignore airplay?
