Hi @parul,

Thank you for choosing Photon!

This is an exception thrown due to a Unity issue in Microphone API / class.

You can try and reproduce using Unity code without Photon code, simply try starting recording using Microphone.Start method and same device (default probably).

So we suggest to try Photon MicrophoneType from Recorder (native plugin) OR contact Unity or Oculus about this error 33. You can submit a bug report to Unity.

I am trying changing microphone type from Recorder to photon .can photon microphone type not depend on Unity Microphone API. How it works can you explain me ?After some testing with Photon microphone type will let you it works or not.

Thanks for testing and confirming it works.

Photon microphone type uses a native plugin for the supported platforms.

Hi @parul,

I wanted to come back to this discussion and maybe add the issue to the documentation.

However, I'm curious, do you disable Recorder.UseMicrophoneTypeFallback? as normally by default if Unity microphone type fails, Photon microphone type will be chosen and used.

@JohnTube we are currently using Photon Voice :v2.15 and Recorder.UseMicrophoneTypeFallback is not in that version .
