Audio: Select a shared audio device by default (#574)
* Audio: Select a shared audio device by default

This ensures that a non-raw audio device is selected wherever possible.

* Audio: Resolve libsoundio version mismatch between bindings and binaries

It turns out we were using bindings generated with libsoundio 1.1.0 git source, but the binaries we were using were built from master git source. I've rebuilt both binaries and bindings to ensure they are version matched.

This should resolve all outstanding issues with libsoundio (including the Linux segfault issue, and the "cannot open device" Windows issue).

* Audio: Reformat MarshalExtensions

* Resolve code indentation issues
