Engineers are currently investigating the issue.
Summary:
Audio embedded with the older RCE format, where the media is a link carrying {{class="instructure_file_link instructure_audio_link"}} with the {{id}} set to {{media_comment_maybe}}, does not render a working player on Classic Quizzes, Assignments and Discussions and give a {{Failed retrieving media sources.}} error instead.
Expected Behavior:
Audio embedded in the older format should play on Classic Quizzes, Assignments and Discussions, matching the current working behavior on Pages.
Workaround:
Remove the legacy link and reinsert the audio through the RCE, which emits the current {{media_attachments_iframe}} embed.
Steps to Reproduce:
Disclaimer: This will illustrate the behavior but most of the embeds that exist in this format are from a few years ago before we changed the standard way we embed media.
- Upload an audio file to an assignment’s description.
- Copy the following legacy audio embed format.
- <p><a id="media_comment_maybe" class="instructure_file_link instructure_audio_link" href="/courses/73279/files/888800/download?wrap=1"></a></p>
- Paste the text out into another RCE html view or just lower on the same assignment, change the course and media ids then save your changes.
- Notice the old link with the {{media_comment_maybe}} id does not play and gives a {{Failed retrieving media sources.}} error.
