Audio: Properly implements audio fallback for SoundIO (#500)

Browse source 
* Audio: Properly implements audio fallback for SoundIO

Given some drivers have issues with SoundIO (for the time being), this attempts to detect if SoundIO can open the default audio device, and then return false in IsSupported if it can't.

* Audio: Handle the backend disconnected event

libsoundio panics by default when a backend disconnects, this catches that event and gracefully handles it.

* Audio: Fix styling nits

* Audio: Fix nits
