Used by the routines at HandleDeathSparkles and CycleColoursWithSound.
Plays a burst of noise for the sparkles of a dying player. The pitch of each cycle comes from the bytes of the ROM, starting at 4660, and the number of cycles depends on the sprite number of the sparkle, so each stage of the sparkles sounds different.
