Your remote audience can’t hear.

FIX: There are 2

• The RACK mic is muted –
  • There is a red line through the mic icon
  • Click the mic icon to unmute, red line goes away
• The Attendee’s speakers are off.
  • Ask the person to tap the up arrow to the right of his/her mic icon
  • Ask him/her to select Audio Settings > Test Mic and Speakers
  • If that still doesn’t cure the problem, their device’s speakers are turned off in their settings.
    • Have them go to their device’s settings
    • Have them check the volume and adjust to the proper level.
