UPDATE - 12/18/2018

Google engineers have confirmed the presence of a bug in Chrome version 71 that affects the activation of audio streams in some applications.

This bug will be fixed in the Canary channel (development) version 73, and then patched into versions 72 and 71 afterwards. We will update here when that fix is available.


SYMPTOMS

  • Cannot activate microphone in Webinato while using Chrome
  • Microphone has full activity meter or no activity meter visible:



SOLUTION 1: ATTACH A WEBCAM


Due to a bug in the latest release of the Google Chrome web browser (ver 71.x) it is impossible to activate your microphone in Webinato without first having a webcam connected to your computer via USB. You do not have to turn the webcam on inside your room, only have it connected and installed on the computer. This includes built-in webcams for laptops.


Once the webcam is connected, activate your microphone as normal following the directions HERE.


SOLUTION 2: USE AN ALTERNATE BROWSER


This issue does not affect other browsers, including Firefox and Opera, which you can download and install separately. Both are acceptable alternatives to Chrome, at least for the time being while Google works on fixing this bug, and are compatible with Webinato.


(for Firefox, you will need the Flash Player plugin, which you can download from HERE)


SOLUTION 3 (Advanced): UNINSTALL CHROME 71 / INSTALL VERSION 70 / PREVENT AUTOMATIC CHROME UPDATES


If you must use Google Chrome, and you have access to install/uninstall programs on your computer, you can roll-back your Chrome version temporarily:


  • Uninstall Chrome from your computer.
    • You will need to remove all settings as well, so be sure to back up your bookmarks and other saved information so they can be recovered later
  • Download and Install Chrome version 70.0.3538.77:
  • Once installed, you have to disable Chrome auto-updates until version 71 is fixed:
    • For Windows, open the Windows System Configuration Manager (Run > msconfig) and stop the following Services:
      • Google Update Service (gupdate)
      • Google Update Service (gupdatem)
    • For macOS, follow these steps to change the default interval for Google to check for Chrome updates to 1 week (604800 seconds):
      1. Launch the Terminal, found in /Applications/Utilities/
      2. Enter the following defaults write command and hit return:
            defaults write com.google.Keystone.Agent checkInterval 604800
      3. Exit out of Terminal and restart Google Chrome
