VIDEO: Explicitly initialize and cleanup SDL Audio subsystem

Browse source 
As mentioned in #873, there didn't appear to be a problem at runtime,
but the formal definition suggests SDL_InitSubSystem and its cleanup
should be called.  It is likely that, as a vestige of SDL 1.2,
SDL_OpenAudio is doing this under the covers.  No harm adding it.
