Hey @h.mizukami Thanks for your feedback. Could you please provide the session ID for troubleshooting purposes? You can find the session ID in the Web portal under ‘dashboard’ \> ‘meetings’, or utilize the `client.getSessionInfo().sessionId` method if the session is currently in progress. Thanks Vic ---

Hi @vic.yang Thanks for your response. Here is the session ID z4yJCwtiSPyozUyTZWW1Og== However…, it might not be a problem with Zoom’s SDK but with iOS instead. [https://discussions.apple.com/thread/255547393](https://discussions.apple.com/thread/255547393) Thanks hiroto ---

Hey @h.mizukami After analyzing the logs, we found that when invoking the `stream.startAudio` method, the `autoStartAudioInSafari` option is set. This option is only applicable for legacy desktop Safari. Could you please remove the option and try again? Additionally, we noticed that you are setting the `backgroundNoiseSuppression` option. Please note that it is not yet supported on iOS mobile devices. We are actively working on this feature and plan to support it in a future release. Thanks Vic ---
