Hello, when I try to Play the audio file nothing happens.

Chrome shows this Error:
Uncaught Error: Error calling method on NPObject. audio.min.js:13
b.play audio.min.js:13
g.(anonymous function).playPause audio.min.js:22
(anonymous function)

Which type of audio-file are you using? mp3 should work.
Can you give me the audio file? (I'm luto on freenode-irc)

I have problem with using irc.
The file with problems is: http://politik-fuer-anfaenger.de/wp-content/uploads/sites/6/podcast/pfa002-kommunalwahlen.m4a
http://politik-fuer-anfaenger.de/wp-content/uploads/sites/6/podcast/pfa001-ep14.mp3

I have changed the m4a to mp3 and now it works.
But it do not work in Safari on a Mac.
