I have no sound and can't hear the presenters.

  • Make sure that the presenter is sharing their mic and your device's volume is turned up.  
  •  If you are using headphones, try unplugging them.   
  •  Is your computer muted? Do your speakers/headphones work? 
  •  Try reloading the room or refreshing the page.  
  •  If that doesn't work, try restarting your browser.  
  •  If that doesn't work, try restarting your computer. 
  •  If this doesn't work, please check your system and Big Marker requirements
