Has anyone been able to upload an ibooks file with audio only files (m4a) in it? I keep getting the following error message during the upload in iTunes Producer: ERROR ITMS-9000: "Files of type audio/x-m4a are not allowed outside of widgets.
Has anyone been able to upload an ibooks file with audio only files (m4a) in it? I keep getting the following error message during the upload in iTunes Producer: ERROR ITMS-9000: "Files of type audio/x-m4a are not allowed outside of widgets. then it names the file as an m4p file. Everything works beautifully on the iPad through Preview, and validates through iTunes Producer up until the attempted upload. If you've been able to accomplish this, please let me know how you prepared your audio files. Many thanks.
