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
