Re: Question about audio device selection

We have not yet taken on audio output device selection for Web Audio.  We
do have an open issue on it (
https://github.com/WebAudio/web-audio-api/issues/359).  I expect this will
take on the form of something like an AudioContext constructor that takes a
deviceId (from MediaDeviceInfo).  (You could also use streams, doing a
createMediaDestination on a getUserMedia of the output stream, but that
would run the audiocontext at the default device's sample rate, which would
obviously be a Bad Thing(tm).)
