Reenable aynchronous audio init stage. Really just single stage with aynchronous enabling of outputs. Keeps audio_init last so prior init steps can use the audiobuffer in any desired way. Audio will be fully initialized by the time the UI is entered. Playback of voice or audio will be delayed properly until audio hardware is ready.
