Zoom Room Raised Hand Notification

When the Zoom Room is the host/cohost of a meeting, the expectation is that when someone raises their hand, there will be both a visual and audible indicator for the Zoom Room host. Testing this extensively has shown that the visual indicator (hand raised icon) appears on the screen, but the audible alert does not happen. We are using Neat Bars and Neat Bar Pros. Has anyone experienced this as well? Is there anything I can do to ensure the audible sound chimes with a raised hand? Any suggestion will be appreciated.
