Audio Delay Issues with Twilio Client and Chrome for Windows

We have confirmed some recent issues with  audio delay when using Twilio Client on a new version of Google Chrome for Windows. Symptoms include longer than normal times for Twilio Client to connect the audio between two parties, and more significantly, audio delays while the two parties are speaking to each other.

The root cause of this issue is related to a new Google Chrome audio and video plugin, Pepper Flash, released with Chrome build 21.0.1180.60 for Windows. For more detailed information about the some of the problems
reported on other sites about Pepper Flash, please see http://code.google.com/p/chromium/issues/detail?id=139953

There are two confirmed workarounds.

Workaround #1

Have your users disable Pepper Flash with the following steps:

  1. In your Chrome address bar, type:  chrome://plugins/
  2. Click on “Details” in the upper right corner
  3. Click to disable this file: pepflashplayer.dll

However, new updates to Chrome will re-enable Pepper Flash, unless you also disable auto-updates in Chrome. To disable Chrome auto-updates, please follow the directions at http://dev.chromium.org/administrators/turning-off-auto-updates

Workaround #2

Use other web browsers on Windows, such as Internet Explorer or Firefox, or an older build of Google Chrome prior to 21.0.1180.60.
