Overview
Audio issues while using Zoom is typically one of two possible scenarios, either the microphone or the speakers. First thing that needs to happen is determine whether the faculty can't hear the students, or if the students can't hear the faculty. This will tell us whether it's a microphone or speaker issue.
Microphone Issue
Students can't hear the instructor.
1. Verify the correct Microphone selection
2. Run Test Speaker & Microphone option within Zoom
3. Check USB connection to the Webcam or AMX Soundbar, try disconnecting it, then reconnecting it.
a. The AMX Soundbar has a front-facing microphone, so if it is facing the students, it may have difficulty picking up the instructor's voice.
b. If the camera on the AMX Soundbar is working, but not the microphone, check the power cable.
c. Webcams with auto-focus may cause disruptions in audio and video, make sure lighting is sufficient.
4. Run Test Speaker & Microphone option within Zoom
Speaker Issue

1. Verify the correct speaker selection within Zoom
