https://mdn.github.io/dom-examples/media/web-dictaphone/ is expecting ogg/opus while media recorder is generating audio/mp4. It might be good to put the right mime type on the blob given to the audio element. Let me know if that fixes your issue.

Marking as behave as expected, please reopen if changing the media type does not fix the issue.
