**Description**  
I’m getting user’s ID inside `onUserAudioStatusChange` delegate and using it to get `ZoomSDKUserInfo` instance using `getUserByUserID` method executed on meeting action controller, but it **always** returns `nil`.

It’s nil no matter when the event is triggered - after joining the meeting and connecting to audio, after clicking on mute / unmute.

Exactly the same code works fine in your Sample App. So I’m wondering what’s the missing piece here.

```
func onUserAudioStatusChange(_ userAudioStatusArray: [Any]!) {

    for userAudioStatus in userAudioStatusArray as! [ZoomSDKUserAudioStauts] {
        let userID: UInt32 = userAudioStatus.getUserID()

        if (self.meetingActionController == nil) {
            self.meetingActionController = ZoomSDK.shared()?.getMeetingService()?.getMeetingActionController()
        }
        let userInfo: ZoomSDKUserInfo? = self.meetingActionController!.getUserByUserID(userID)
                
        if(userInfo != nil && userInfo!.isMySelf())
        {
            self.mySelfUserInfo = userInfo!
        }
    }

}

```

**Which version?**  
4.6.21666.0427

Hi @dmiskiew,

Try to get user info in `func onUserInfoUpdate( _ userID: UInt32)`. Also please take a look at `getParticipantsList()` method of `ZoomSDKMeetingActionController`, you can use it to query connected users.

Good luck!

Hey @dmytro,

thanks for your suggestions!

Unfortunately getting user inside the `func onUserInfoUpdate( _ userID: UInt32) ` doesn’t work - it returns nil.

And getParticipantsList() return’s nil too…

Hi @dmiskiew,

Thanks for the post. Please have a try to retrieve userID from `(void)onUserJoin:(NSArray*)array`.

Hope this helps. Thanks!

Thanks for the answer @carson.zoom!  
Retrieving userID from `(void)onUserJoin:(NSArray*)array` doesn’t help.  
But I finally figured it out by deleting line by line from the sample code.

The nil is returned if there’s no `ZoomSDKMeetingServiceDelegate`.  
Connecting the delegate with `onMeetingStatusChange`, `onWaitMeetingSessionKey` etc solved this problem.

Hi @dmiskiew,

Thanks for the reply and glad to hear that the problem has resolved. I will pass this to the engineering team to further enhance this. Pardon the confusion here.

Thanks!
