Steps to reproduce

Using Philips SpeechMike or Olympus DirectREC microphone with the audio API, when the speakers’s device are set as default, the demo https://developer.microsoft.com/en-us/microsoft-edge/testdrive/demos/microphone/ doesn’t work properly

// initialize mic source
sourceMic = audioContext.createMediaStreamSource(stream);

sourceMic is not the correct node when the default rendering device is the multifunctional device itself. so the audio streaming is null

Setting as rendering default the internal speaker, the sourceMic node is the one right and the code works properly
