What I'm hoping is that there's some what to direct it to use a particular device, and then WebKit proper and all of the plugins will use that device.

platform/audio is used by the Web Audio APIs <https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html> only and not other audio output (plug-ins, media etc).
