Hi @tmiskiew,

Thanks for the reply. If you are trying to use `getUserByUserID`, please try to retrieve the userID from `(void)onUserJoin:(NSArray*)array`, and for the question in [actionMeeting Unmute returns ZoomSDKError\_WrongUsage - #7 by carson.zoom](https://devforum.zoom.us/t/actionmeeting-unmute-returns-zoomsdkerror-wrongusage/18990/7), you may refer to my answer in that post as well.

> @sam.decrock Thanks for helping out! slight_smile Hi @dmiskiew, Thanks for the code snippet. If you would like to unmute yourself, you will need to pass a real userID, passing 0 will not work. And the ActionMeetingCmd needs to be called if and only if you are in the meeting. Hope this helps. Thanks!

Hope this helps. Thanks!
