title: Why isn't the iOS browser playing audio from this MP4 video?
body: <p>I have 100+ videos encoded in <code>H.264 video</code> with <code>MP3 audio</code> for a <code>HTML5-video</code> project, but the Audio won't work on iOS. (No sound, but working video). It works perfectly on Android. They all have the same encoding setup, but <a href="https://1fichier.com/?h75gujhtyhle1mheq036" rel="nofollow noreferrer">here's</a> one of the videos</p>
  
  <p>Googled for several days and can't seem to find any known problems with <code>iOS</code> and MP3-audio. What's wrong?</p>
