What are the limitations of HTML5 audio on Android and iOS?

I’ve noticed that for the HTML5 Audio element, what works on the latest version of Chrome for PCs will not necessarily work on the default browser in Android, Chrome for Android, or Safari on iOS.

What limitations exist for Audio on these platforms?

  • How to check if network is available on Android and iOS ( Delphi XE5 )
  • Can iOS receive broadcasts like Android?
  • Objective C - UIWebview to load only a certain part of the webpage?
  • Remove selection gray shadow from html input on iOS
  • Detect uninstall event in phonegap app
  • Phone: numeric keyboard for text input
  • Specifically:

    • Which audio formats are supported on each platform?
    • For each platform, is a user interaction event (eg. onclick) required to play audio from javascript? (via new Audio(url);)
    • Can audio be played from a data URI on the Android and iOS Audio element?
    • Are there any other major limitations (or bugs) for HTML5 Audio on these platforms?
