Notes:

• HTML5 audio output selection is currently supported only on Chrome browser and its clones, and only whenthe HTML page is accessed using "http://" or "https://" URLs.

• Due to either unclear Web API specifications, or incorrect browser implementation, permission to accessmicrophone is required for selecting audio output device. In current browser implementation, themicrophone permission covers both the audio input and output devices, regardless of the device type suchas microphone or line-in.

• This script has not been tested under platforms other than Windows.
