play() or load() must be called ONCE from a user gesture handler for each <video> and <audio> element. This is to prevent pages from loading potentially large media files which the user never plays, which is especially important in markets with expensive metered bandwidth. 

iOS does treat <audio>/Audio() like WebAudio - a user gesture is only required for the first load/play. The restriction is removed after that point, so you can load/play one file and then change 'src' and load and play another without a user gesture.
