I'm not sure that I understand and I feel a bit silly but
The examples are not my projects. Cerberus one, comes with Cerberus app, installed in the app folder and fantomCX one, comes with fantomCX module, installed in the examples folder. So they are local? I just opened them, built and launched for the Html5 target. Safari refuses to play the audio. Firefox plays fine. I didn't test them in Chrome yet.
