Audio issues with break-out rooms using Amazon Fire Omni TV

We have an Amazon Fire TV 65" Omni Series 4K UHD smart TV  with built-in Zoom. We use a Logitech C920 Hd Pro Webcam, which is recommended by Amazon.

The tv works great when you are doing a normal Zoom meeting, even with multiple attendees. However, there is an audio problem when we use the break-out room function in Zoom. To be clear, there are no audio problems on our side; the problems are experienced by the people in a break-out room. That is, the people in the break-out room complain of two different things:

1. Hard to hear me when I am speaking and/or
2. Feedback when I am speaking.

We have found that the problem goes away if we mute when the people in the break-out room are speaking, and they mute when I speak. We are looking for a more ideal fix.

Thanks.
