"getUserMedia" is first called for both audio and video and then, if the camera was not found, it was called again only for audio. In some cases (for example, in Windows if the camera device is being used by another application, or if permissions for the camera are not granted at a system level) it could happen that a camera device is found but it can not be accessed by the browser. If that happened "getUserMedia" was not called again only for audio and the microphone was also seen as not available, even if the problem was only with the camera.
