Hey @satyam.gupta, Thanks for using the dev forum! Unfortunately, that version is too outdated for developer support. Can you update to the latest version? Thanks! Michael ---

> [@Michael\_Condon](#): > > using the C++ SDK or the C# SDK Wrapper Hi @Michael_Condon , Replying on behalf of Satyam here, the issue is occuring intermittently and we are unable to identify the condition in which this occurs to be able to reproduce this. So, we don’t have the step to reproduce this. Secondly, upgrading the version and testing it in production will require significant bandwidth and time from our end, as we would need to get our client tested against all our use cases for which we use Zoom SDK, before sending it to production. So, the upgrade So, it would be great if you can help us identify the issue through the logs and let us know if upgrading will help or not Thank You, Rishi ---

Hey @Rishi_Sharma, We can try to look at the logs, but if this wasnt fixed in an update we would need you to update again when we release a new version with the fix. Can you clarify what the exact issue is? I am not sure I understand from the initial post. Thanks! Michael ---

@Michael_Condon Ideally before an ActiveAudioChange event we should be getting a AudioJoinedEvent callback. But for some meetings this was not the case. ---
