I was working updating the example audio question that ships with the question type. I used the editor audio button to create the audio and it appeared to work nicely. However it wouldn't play in Mac OSX.
The rtc recorder button seems to save in Ogg format. Does anyone know if this is a general problem with OSX. It works fine with mp3 files. Also is it possible to switch the default recording format to MP3 which has wider support than Ogg? I cannot see a way of doing it.
