            Bug ID: 149367
           Summary: REGRESSION: WebAudio user-gesture restriction is no
                    longer lifted by touchstart event
    Classification: Unclassified
           Product: WebKit
           Version: Safari 9
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jay at kodewerx.org

Safari 9 lost the ability to change the AudioContext status to "running" from a touchstart event.

The unit test uses a mousedown event: http://trac.webkit.org/browser/trunk/LayoutTests/webaudio/audiocontext-restriction.html?rev=183424#L45 runWithKeyDown() is called, and: http://trac.webkit.org/browser/trunk/LayoutTests/webaudio/resources/audio-testing.js?rev=183424#L198 mousedown event is triggered.

mousedown and touchend events can be used to lift the restriction. touchstart no longer works.

Possible regression from #144211 ?
