; This variable has another use related to fade-out, as well. PlaySound stores
; the sound ID of the music that should be played after the fade-out is finished
; in this variable. FadeOutAudio checks if it's non-zero every V-Blank and
; fades out the current audio if it is. Once it has finished fading out the
