- Are they able to open any web pages?
- Are they prompted or do they have an open prompt to install WebEx or Zoom?
- If you send them a mail with the meeting link do they receive it? Are they able to open and connect with it?
First, see if the user is using the system speakers or a headset; make sure the system audio is not muted by checking the volume indicator and increasing the volume to ensure the system is not muted. Check to see what the correct output is selected in the remote client software; In Zoom and WebEx, by clicking on the arrow next to the microphone icon, you can change your selected audio input and output and access the sound setup and test panel. If using a Mac, please check the privacy and security permissions are enabled for the speakers.
