The sdl_audio_init() function is replaced with audio_sdl_realize(), which initializes the SDL audio subsystem before delegating to the parent class realize method. The sdl_audio_fini() is replaced with audio_sdl_finalize() to properly clean up the SDL audio subsystem. Access to the Audiodev is now through hw->s->dev instead of the drv_opaque pointer.
