Review comment (refactor):
Instead of blindly searching for a URL that looks like this I would extract the actual json data:
```suggestion
        data = self._search_json(
            r'<script[^>]+\bdata-media-id=[^>]+\btype="application/json"[^>]*>',
            webpage, 'audio data', audio_id)
```
This should be more resistant towards CDN changes
