I am having a problem with echo and feedback when I attend a Breeze meeting.
Echo happens when multiple people, who aren't wearing headsets, have the talk button locked to an on position. The microphone on the camera picks up the audio from the computer speakers and feeds it back to Breeze. To avoid the echo feedback either wear a headset with a microphone, or press the talk button when you want to talk and release it when you have finished instead of using the hands-free button to lock it on.
If no headset is available or the meeting is being projected to a group of people who all need to be able to hear, echo and feedback can be decreased by NOT using the hands free lock button on the talk button. In this situation you would need to press and hold the button when you are speaking and release it when you are not speaking.
There is a setting in the Flash Player Settings window that might also help some with echo. From the Meeting menu, select “Select Camera…..” Click on the microphone icon and check the box beside “Reduce Echo.”
