LRC assistants may get called by students with this error regarding pluginfile.php in a Moodle quiz, it appears in the audio player interface itself and looks like this:
1. The error messages flashes only briefly, and afterwards the audio simply will not play.
2. In a Respondus lockdown browser quiz, you can bring up the error message again by clicking “next” and then resuming the attempt. When the quiz page reloads, the error message will briefly flash again.
LRC assistants cannot work around this error, they need to alert permanent staff. Usually it is related to a quiz author needing to update the audio file link, like so:
1. Go into the quiz, on the left, click “edit the quiz”):
2. Find the audio file link, edit the link:
  1. Can you actually load the link? If it says “file not found”, you have the root cause:
  3. Does it say “draft” in there? Not good. Copy the unique identifier from the path:
3. Go to in Moodle course / Files section, locate the offending file (you can use the unique id you put in the clip board to search), i.e. make sure it actually exists:
4. Get the correct URL for the file, puit it int the clipboard:
5. Go back to editing the quiz, update the wrong URL with the correct one.
6. Save the updated quiz.
Now the student can reload the quiz, if in Respondus lockdown browser, like above by clicking “next”and back.
