The microphone API is not yet supported in Web, so a warning message has been added to inform developers of this limitation and the permissions are not asked.
Reproduction steps:
1. Open the attached “WebGLMic.zip” project
2. Build and Run the project for WebGL (File > Build and Run)
3. Observe the Player in the Browser
Expected result: Microphone permissions are asked or a message pops up saying that microphone API is not supported
Actual result: Webcam permissions are asked
