I'm writing an app using cocos2d and libpd on iOS. After updating XCode to 7.1 I had to do a workaround regarding CG shaders not setting up correctly, as per: Coco2d 2.1 and Xcode 7 iOS 9 crash ccShader

Unfortunately I started getting crackling noise on playback on iOS9 and 9.1 devices. Pre iOS 9 don't display this problem. I'm wondering whether it has something to do with the shaders workaround.

anybody with the same issue?

It turned out that crackling has nothing to do with iOS9 or XCode 7. The object initialising libpd has been initialised twice causing the audio engine to have two active copies.
