Sorry, now I understand what you mean by replicating. Here are the steps I followed:
1. I added an activity under a topic and I chose Quiz as the activity.
2. I went to the quiz I created and clicked "Add a new question" in the quiz editing section.
3. I added a multiple choice question.
4. In the question text area, I clicked "Insert media". In the insert media window, I clicked the Audio tab and I clicked "Browse repositories" and "upload a file".
5. I uploaded an mp3 file.
6. I clicked "Insert media".
Everything looks fine in the question text area, it displays as an audio player. But when I click "Save changes" and view the quiz, the audio player is gone and instead there is a video button, play button, duration time etc. as seen in the screenshot.
This is how it looks -everything is OK, there's an audio player- before I
save the question. After I save the question and view the quiz, the
audio player disappears and video buttons appear instead of the audio
player.
We didn't have this problem with Moodle 3.0.2
