I'm trying to get into the Web Audio API as I'm looking to make some visualizations based on the music that's playing. However all examples I have found, it's like the audio is muted. It plays the file but there's no sound.
For example: codepen.io/noeldelgado/pen/jqibm
Even following this - https://www.youtube.com/watch?v=IBHpSkGZtNM yields same result.
I'm on mac, using the latest version of Chrome (42.0.2311.90), have also tried on latest Firefox and it's the same problem.
