Web Call Sound Trouble? Start Here!


Ensure you are using Chrome or Firefox
(Internet Explorer, Edge and Safari don’t support WebRTC…yet)

Download Chrome!
Download Firefox!

Make sure your internet connection is decently strong to avoid having your connection to the call drop, and to ensure the audio isn't choppy and laggy.

Quick Fixes

If you have problems connecting by web call, the best choice may be to simply close the web call window to connect a different way, such as by phone, webcast, or Skype. Otherwise, you may miss several minutes of your event trying to troubleshoot web call.

Another "quick fix" is to try using a different web browser, i.e., if you first tried with Chrome, try Firefox instead, and vice-versa.

A final thing to keep in mind is to make sure you don’t have too many other applications open as they might interfere with your seminar in unexpected ways.

When your web call window first opens:
Make sure you hit “allow” on the popup to access your microphone/camera.

If anyone is having trouble hearing (or seeing slides):

Check to make sure that the conference has started. The event page should display "event live."

In Firefox: To change your microphone and make sure you always allow the connection from the “share selected devices” drop-down menu.


Make sure you refresh after making a change to ensure it takes effect.

In Chrome: To make sure you are allowing our system access to your microphone.



If that doesn’t work you should check your system preferences, and ensure your input and output are set to the correct device. If you are using any microphone that is not the default this is particularly important. Instructions on how to do that for PC and Mac are below.

On PC: On your desktop click the Start Menu and find the Control Panel . In the Control Panel click the icon labeled Sound . In that area you will see the choices below. Make sure the proper devices are selected for your input and output. Always remember if you want to save what you have done you have to exit by clicking the OK button and not the red X.

On Mac: Choose Apple Menu then System Preferences , then click Sound. In that area you will see the menu below. Make sure the proper devices are selected for your input and output.

  • I can hear the host, but the host cannot hear me.
    This may not be a problem at all: not all hosts enable you to unmute your mic. Submit a question via the online question form to ask if you should be able to unmute yourself.
  • If you are having trouble after being previously connected, sometimes a refresh will fix the problem. You can refresh the browser window by hitting the refresh button in the browser toolbar, the F5 button on your keyboard or the combination of the keys Ctrl + R on PC or Command + R on Mac.
  • If you still can't connect, or if you get connected for a few minutes and then disconnect after a certain amount of time, you may have a security setting in your network, on your computer, or a plugin in your browser that is interfering.
  • Sometimes, there are simply problems on the internet, either with your direct internet provider or on a "hop" between your provider and our servers. These kinds of problems are intermittent and usually clear themselves up, but to fix the immediate problem, you may want to try webcast or phone instead.
