title: Loading issues with Ionic webview plugin
body: <p>I'm using the Ionic webview plugin for Cordova to port my HTML5 game to mobile devices, but it's having trouble loading some of the audio files. It will load a few of them, but then arbitrarily gets stuck on one.</p>
  <p>Giving me this error:
  <code>Uncaught (in promise) NotSupportedError: Failed to load because no supported source was found.</code>
  I don't think it's a CORS issue since it loads some of the audio files, and in any case the webview is just requesting the audio from https://localhost which I believe is being served by the webserver that comes with the plugin, so I wouldn't think there would be any cross-origin shenanigans happening.</p>
  <p>Has anyone run into this issue before? If so, how did you fix it?
  Does anyone have any insight as to how this plugin works so I might debug it myself?</p>
