Created attachment 463688 [details] The static page to reproduce the bug Behavior in Chrome (if known): Same Behavior in Firefox (if known): Same Video and audio issue. Once add listener for 'touchend', as it will resume the AudioContext when 'touchend'. Yet when we touch and slide, the 'touchend' event was triggered but the audio context cannot be resumed somehow. ## Flash or HTML5? HTML5 ## What steps will reproduce the problem? (1) Open the page with mobile browser, or use devtool responsive util to make the touch events work. (2) Open the console. (3) Slide ## What is the expected result? AudioContext will resume successfully. ## What is the actual result? AudioContext cannot resume due to the safety policy, it can only be resumed with 'touch as click'.
