title: HTML5 Volume Increase Past 100%
body: <p>This has been posted a few years back, but has still gone unresolved. I'm determined to make something that plays the video at a volume let's say 150%, but HTML5 volume method has an error with any value greater then 1. 
  <a href="https://www.w3schools.com/tags/av_prop_volume.asp" rel="noreferrer">https://www.w3schools.com/tags/av_prop_volume.asp</a></p>
  
  <p>Here's my code:</p>
  
  <pre><code>javascript:(function(){document.getElementsByTagName('video')[0].volume = 1.5;}());
  </code></pre>
  
  <p>0.5 works but not 1.5. One answer said that it gives this error: </p>
  
  <pre><code>Uncaught DOMException: Failed to set the 'volume' property on 'HTMLMediaElement': The volume provided (2) is outside the range [0, 1].
  </code></pre>
  
  <p>Anyway I can do something with this exception to have it run beyond the range [0,1]??</p>
