Make sure your computer is not muted or set to very low volume. To test this, 
see if you can hear other sounds that your computer normally makes, such as 
beeps when you press an incorrect key, or sounds that signal that a message 
has arrived. 

Verify that the sound output device (for example, headset) you are using is 
selected and not muted. Choose System Preferences > Sound, then click 
Output and examine the selections. If you make changes, you may need to 
restart the computer. 

If you are connecting via virtual private network (VPN): In the VPN 
application window, click the Options menu. The Stateful Firewall option

to remove the check mark.

Verify that the sound input device (for example, headset or camera) you are 
using is selected and not muted. Choose System Preferences > Sound, then 
click Input and examine the selections. If you make changes, you may need 
to restart the computer.
