Zoom audio settings
When you join a Zoom meeting either as a host or participant, you may be prompted to "Join with Computer Audio" before you can hear or speak with others in the meeting. Before joining, you can click "Test Speaker and Microphone" to confirm your setup is working. If you don't wish to see this prompt again, you can check the box next to "Automatically join audio by computer when joining a meeting".
