I noticed recently that audio files have stopped working in the cache. When trying to download I get a message “Stored file has disallowed content type (audio/mpeg)”
I found that changing the function send_local_file in classes/diskcache.php to allow “audio” in the regex: "/(image|video)\//" -> "/(audio|image|video)\//" solves the issue.
