The handler for sound effect actors with the ID 22. Each time it is called it plays the next note from a table of periods. The table address is held in the actor (IX+2 and IX+3), and the notes are played from the end of the table towards the start. The number of cycles in each note is held in IX+4. The actor is removed after the first entry of the table.
