Unity 5.4.0b25 and Voice 1.4 on iOS

Hello,

Here is my problem, when I launch the demo of Voice, the runtime break on the opus lib.
Here is a screenshot in xcode : http://littlebigben.fr/xcode_punvoice.png

To reproduce the bug, just create a new project, import PunVoice 1.4 and build for iOS.

Why do I use the Unity beta?
I needed to update Unity to 5.3.5 to be able to publish on Apple store (because of the ipv6....).
But my project is a VR one, so in the latest stable versions of Unity the UI doesn't work with the Google Cardboard SDK (because of Unity RenderTexture issue).
So they solved it on the beta version!

Thanks for your help,
Benjamin
