I have an apache configuration problem that I hope someone will shed some light on, i have a test page with html5 audio tag pointing to an m4a file on my server, all browsers except for IE are able to play this file although in the mimetypes, audio/mpeg mp1 mp2 mp3 m4a are defined. Strangely enough, if i change the extension of the file to .mp4, IE will play the audio. Any hint about that?

  • Is the m4a defined as audio/mp4?
