title: QR Code playing video on iPhone but not playing the sound
body: <p>I have a QR code set up to play a video.</p>
  
  <p>It is pointing to an MP4 file, which works fine with sound when navigating to this using safari on the iPhone.</p>
  
  <p>However, when I use the QR code to view the video on the iPhone the sound isn't working.</p>
  
  <p>Here are the links for reference.</p>
  
  <p>Video file: <a href="http://www.remarkablegroup.co.uk/temp/prokill.mp4" rel="nofollow noreferrer">http://www.remarkablegroup.co.uk/temp/prokill.mp4</a></p>
  
  <p>QR:<img src="https://i.stack.imgur.com/drzIe.png" alt="enter image description here"></p>
  
  <p><strong>Additional information</strong></p>
  
  <p>I created the QR code using this online generator: <a href="http://qrcode.kaywa.com/" rel="nofollow noreferrer">http://qrcode.kaywa.com/</a></p>
  
  <p>All I did was point the QR Code directly to the file name so that it would use the phones built in functionality.</p>
