Help !!! ......BeoPlay A9

My Beoplay does A9 setup normally with the white led light on. I could see on IPhone. But it can not play music? I have tried to used itune on Laptop to play. However, it only stop at connecting state, and could not play music. Could you please explain for me? Do you have any suggestion to solve this problem?

I had the same problem with playmaker. On my airport extreme i use wpa2 password protection. But when i set up my playmaker using beosetup app it only ask for network name and pass. When i checked settings standrad wpa protection was set in app. When i manually change this to wpa2 airplay works fine. Before that it shows on network but do not play over airplay any music
