          Whilst Moodle itself generally won't include empty stylesheets, some Chrome extensions (including Google's screenshot tool, https://chrome.google.com/webstore/detail/cpngackimfmofbokmjmljamhdncknpmg) can inject empty stylesheets into the page - the aforementioned screenshot tool was the culprit in my case. I guess that's one way to test this - install that extension (it's handy to have anyway!).

          Description

          If any empty stylesheets are present, Chrome will not display the MP3 Flow Player. This is similar to MDL-29980, though happened after the MDL-26697 changes were merged.

          A quick and easy fix is to add the following line just after line 1712 of /lib/javascript-static.js (as per current master) - i.e. between the if and the for loop:

          if (!allrules) continue;
