title: CHHapticEngine not running
body: <p>After a day of playing with the <code>CHHapticEngine</code> and custom haptic patterns, using AHAP files in particular (including adding sound samples), I have lost the sound and haptics in the deivce / iPhone. After a factory reset of the iPhone, there are still no haptics / sound in the device (no ringer, no vibrations etc.). When trying to start the haptics engine and play any pattern I can see the following output in the Xcode debugger:</p>

  <p>The question is, is it probable to damage the hardware from code?</p>
