You can also include audio and video in HTML widgets. iBooks Author doesn't optimize video or audio files included in HTML widgets like it does for Media and Keynote widgets. You will need to prepare video and audio for HTML widgets manually.
- For video, you should use files with an .mp4 file extension.
- For audio, use files with an .m4a file extension.
- You cannot use media that has .m4v or .m4p file extensions.
Note: Video and audio media in HTML widgets are not DRM protected.

i tried adding sound in m4a format but still it is not working. Previously even mp3 audio files worked but it stoped working after ibook updates i guess More over the audio controls keep on showing cannot play audio.
