The "Click to record your answer..." link is seen when reviewing submitted assessments. Even nothing can be recorded after the link is clicked. This should get removed to avoid confusion.
Here is how to reproduce this issue:
1. Create an assessment with audio questions.
2. Login as student. Take that assessment, record something, and then submit the assessment.
3. Click the submitted assessment to review the submission. You will see the "Click to record your answer..." link at the bottom of the audio question.
