Hey mars1985 , thanks for the heads up!
I'm also a frustrated iOS game dev. I've created an iPhone game using Construct 2 and I'm just waiting for this bug to be fixed (by Scirra or Apple).
Since iOS 9.2 the audio is distorted. I've tried different export and build combinations to find a way to fix it with no success.
Right now I'm using a Cordova Export with a Phone Gap build. The audio is fine on Android but distorted on iPhone.
I've also tried to replace the sound events in my game's javascript file with this "touchend", but I found it impossible to understand that file.
I also would like to ask Ashley to try to reproduce this error on an iPhone please, not on an iPad. The majority of iOS players are iPhone users. The iPhone also sells more than iPads. Please do it.
A sneak peek of my game, just waiting for this fix to be launched:
