Sound problem in a multi people zoom meeting

[Xiangjunpan]

People can't hear me in a zoom meeting hosted by others and more than two attendees.  I don't have this problem in my own zoom meeting or in a one-on-one zoom meeting.  It is really troubling.  Can any one help?

This happens to me too!! It helped once when we deleted the app and reinstalled it but it's still not very good. Following in case someone else has an idea.
