Major Storyline Audio Playback Issues

I got a code to paste to index_lms.html from Claude AI that makes every video/audio file a "unique" ones by adding a random string to it query string.

Basically, chrome always treats it as a new file, and it doesn't try to cache it in any way, so it should fix the problem. Also, it doesn't affect any course playback from my tests.

You can give it a go if you want and let us know if it did help. I'll also report soon. I have a course that is mandatory for 350000 people worldwide, lol.

<script>
(function () {
  function bustCache(el) {
    var src = el.src || el.currentSrc;
    if (!src || src.indexOf('blob:') === 0 || src.indexOf('?cb=') !== -1) return;
    console.log('[cache-fix] busting:', src);
    el.src = src + '?cb=' + Date.now();
    el.load();
  }

  function processAll() {
    document.querySelectorAll('video, audio').forEach(bustCache);
  }

  // Observer na cały dokument — przechwytuje media dodawane przez Storyline
  var observer = new MutationObserver(function (mutations) {
    mutations.forEach(function (m) {
      m.addedNodes.forEach(function (node) {
        if (!node.querySelectorAll) return;
        node.querySelectorAll('video, audio').forEach(bustCache);
        if (node.tagName === 'VIDEO' || node.tagName === 'AUDIO') bustCache(node);
      });
    });
  });

  // Podepnij jak najwcześniej — nie czekaj na load
  function init() {
    processAll();
    observer.observe(document.body || document.documentElement, {
      childList: true,
      subtree: true
    });
  }

  if (document.body) {
    init();
  } else {
    document.addEventListener('DOMContentLoaded', init);
  }

  // Dodatkowe przejście po load — na wypadek gdyby Storyline
  // inicjalizował media po zdarzeniu load
  window.addEventListener('load', function () {
    processAll();
  });
})();
</script>

Paste it right before </body> tag in for example notepad.
