It used to work fine. And suddenly my airplay button disappeared. After googeling a bit I found some threads which pointed out the option of enabling the option “Look for remote speakers connected with AirPlay.” in the iTunes preferences. No such thing there for me.
Someone pointed me to this thread. https://discussions.apple.com/thread/2594307?start=0&tstart=0 But when I try to disable my firewall, Airplay still doesn't work.
Anyone any ideas on what the problem might be? Hope someone recognizes this problem...
