I have created a panoramic demo, here:

Playing animation using WebGL works fine. Playing audio using the Audio tag works fine. However, playing both animation and audio has some problems:

1. In Chrome, sometimes the audio will stop after a minute or so and won't resume. But after Reload the music will probably finish. And yes, I DID use the audio.load() function.
2. In Minefield it doesn't work at all. So I had to state that demo works only in Chromium.

Did anyone had similar problems?
