Log:

Rewrite of CoreAudio driver.

While not everything is fixed yet, it is a step in the right direction.

-You can now select which device to use in the setup and not always have to use the default audio device.
-Fixes #5552.
-Properly set channel layout, under most circumstances, you shouldn't have to use Audio Midi Setup utilities

There are still bugs that I can't explain, probably due to my lack of deep knowledge of CoreAudio, and it certainly ain't behaving as it should. In particular, switching from AC3/DTS bitstream back to PCM will fail except if you have selected the default output device.
Until this is resolved, it is best to keep using the default output device.

  Cherry-pick: #267cada
