I am currently working on a website that includes a musicplayer made with SoundJS. I, myself, am using Google Chrome to test and debug my website, and it worked like a charm, but when I recently tested it in FireFox, I noticed this strange error.
When I hit the play button and the sound is being registered I get this error:
The buffer passed to decodeAudioData contains an unknown content type
The code I use in my javascript file to create the soundInstance: 'response' is a string containing the location of the .mp3 file (this all works perfectly in Chrome).
createjs.Sound.registerSound('uploads/songs/'+response,'song');
When I test this same piece of code with an 'ogg' file it works perfectly in FireFox. I also heard from some people that it doesn't work in Safari too, but unfortunatly I am a windows user.
If you want to test it for yourself: www.playmesome.be . Just hit the play button and it will keep on loading infinitely because of this error.
Thanks for reading!
