## [Essentials](Functions-(Essentials))

!> `FAudioGMS_Init()` and `FAudioGMS_Update()` are absolutely essential to FAudio playback. You should run `FAudioGMS_Init()` at the start of your game (usually on boot) and `FAudioGMS_Update()` should be run once every frame, usually in the Step event of a persistent instance. If in doubt, place the `AUDIO` object in the first room in your game.
