JavaScript Audio : MEDIA12899 AUDIO/VIDEO : type MIME

Question

I'm playing an audio file with this code :

var snd = new Audio("sound.wav"); // buffers automatically when created
snd.play();

This was working well on every up-to-date well known browsers when I deployed my website (mid-2013).

However, today I've re-tested this functionality on IE11 and the sound hasn't been played. Opening the standard developper console on IE11 gives me this error :

MEDIA12899: AUDIO/VIDÉO : type MIME.

And it still works on Firefox 27.0.1

Thank you for your help.

Answer 1

I had the same problem and found that IE does not support wav format in audio or video HTML elements.

Found similar question answered in another post:

Answer 2

Have you tried adding AddType audio/wav .wav to your .htaccess file to make sure it knows how to encode the file?
