raspberry pi airplay problem with iPad (iOS 8.4.1)

Hello!

I’ve just installed the latest (1.55) volumio on my raspberry pi and it seems to work to a large extent. I enabled airplay and volumio is detected as an airplay device which I can connect to, using for example my iPad (iOS 8.4.1).
When I stream from my iPad it looks like the music is playing (progress bar is moving etc) but no sound comes out of the raspberry pi.

However, if I use the program Airfoil (4.8.14) on my macbook I can stream to the raspberry pi without any problem.

Anyone who have had this problem before or have any ideas how to solve it?

Thanks in advance!

Cheers
Erik

sorry, maybe a stupid suggestion but is the volume up on your iPad ? I am using iOS 8.4.1 (12H321) without a problem.

Yes. (I also have release 12H321)
