Zooms preferred method of handling audio in meetings is to join via computer audio. If you are experiencing issues with that, here are some tips and resources to help.

1) If you are having issues with your webcam or computer audio, join a test meeting using this link: https://lbc.zoom.us/test 

2) If you are still experiencing issues with an audio connection, please connect using your phone for audio.
