I’m sorry that you’re having trouble with audio during your session.  Here are a few things to try:

First see if Chrome might be blocking audio in one of these two ways:

  • Be sure there are no updates for your system (drivers) and that you are running the latest version of Chrome for your research study.
  • Ensure that the computer isn’t muted.
  • Try adjusting the volume up and down and making sure no external mute buttons are active.
  • If you are using the internal speakers, test with a set of headphones.
  • If using headphones, try the internal speakers (headphones are recommended during testing if possible!)
  • If using external speakers, adjust the volume control (most external speakers have their own volume controls as well)
  • If using external speakers, try a different USB port.
  • Try playing a song.  
  • Additional Chrome settings:  

Mic and Cam defaults can be accessed in a number of ways in Chrome, but the easiest is to paste the following links into your URL bar:

Cam:  chrome://settings/content/camera

Mic:  chrome://settings/content/microphone

  • Restart the computer.

On Macs running Mojave (10.14.x) or above, please double check apps that ask permission for camera and mic in the System Preferences, under the Security/Privacy tab:

Keywords:   sound, microphone, nosound, audio, mic,  blocked
