1164814 - AudioContext.currentTime is still increasing when suspended from the devtools

Status: RESOLVED FIXED

(Core :: Web Audio, defect, P3)

Description

[Duan Yao]

Steps to reproduce:

In devtool's console, run these codes:

var ac = new AudioContext;
ac.suspend();
// wait seconds
ac.currentTime; //1
// wait seconds
ac.currentTime; //2

Actual results:

AudioContext.currentTime keeps increasing while the context is suspended.

Expected results:

AudioContext.currentTime should keep the same after suspend().

According to the spec, suspend() should "Suspends the progression of time in the audio context" (http://webaudio.github.io/web-audio-api/#widl-AudioContext-suspend-Promise-void). Chrome 42 does suspend the progression of currentTime.

A clarification: you must not run the 2 lines at once, or suspend() has no effect because AudioContext is initially suspended:

  var ac = new AudioContext;
  ac.suspend();

You should run the 2 lines one by one in the console.

This works as intended in web pages, but not in the console for some reason. See the attached test page.
