Echo on Meeting

Good morning,

I integrated MacOS zoom SDK in my app. While i start meeting in latest macOS High sierra and someone joins on other device some annoying noise or echo is coming. Every time when someone talk  in meeting some noise or Echo is coming. How can i avoid that noise. Is there any method or function? 

Hi, echo usually happen when the participants who sit near by join the meeting, we haven’t provide method to reduce noise,I suggest to mute the participate who’s not speaking.
