Hello,  
Can someone provide some sample code for the method below. I’m trying to detect the active users (users who are talking) during a zoom meeting.

AudioCtrlEvent-\>onUserActiveAudioChange

See below the member function documentation.

Hi @umeta,

We do not have the exact sample code for `onUserActiveAudioChange` in the demo app, but you could refer to the implementation of `onUserAudioStatusChange`, subscribe to the event, and the callback will be trigger when the active user’s audio has changed:[https://github.com/zoom/zoom-sdk-windows/blob/69f8ff8310a4e52fd26be42d7547854484600940/demo/sdk\_demo/EventMgr.cpp#L249](https://github.com/zoom/zoom-sdk-windows/blob/69f8ff8310a4e52fd26be42d7547854484600940/demo/sdk_demo/EventMgr.cpp#L249)

Thanks!
