Photon voice 2 not working on build!

I'm trying to use photon voice. When running in the editor it works. But when running on Build it doesn't work.

Assets/Photon/PhotonVoice/PhotonVoiceApi/Platforms/Unity/MicWrapper.cs Line: 39)

  • Make sure that you pass the id of existing device (from Microphone.devices list) or empty string for the default device when initializing the microphone.
