Audio Settings in Zoom
To open Audio settings, click/tap the small up arrow next to the mic icon. I have outlined it in red in the illustration. It will display a menu very similar to the one below. I have no external equipment installed in this example, so the only choice is the audio equipment that is built in to a MacBook. If you have USB equipment plugged in, you will see it listed here and you can choose it easily by clicking on it.
The setting that we need for troubleshooting is the Audio Settings. You can click that as shown in the illustration. This will open the system settings for your computer.
Setting 1 will allow you to test your speakers. If you are not hearing the class, start here. Slide the output volume up and down to a comfortable level.
Setting 2 will allow you to choose different speakers if you have more than one set of speakers connected.
Setting 3 will allow you to test your microphone. Sliding the input volume will make your voice louder and softer to the others in the meeting.
Setting 4 will allow you to choose between microphones that are connected to your system.
Occasionally having too many mics/speakers connected will cause conflicts. If you suspect that is an issue, start by disconnecting all external equipment and plug in one item at a time to find the best configuration.
