The handler of the sound entity for the sound set up by SoundsEating. The count in the second byte of the entity is decreased on each pass of the main loop. When it goes below zero the entity is cleared. Until then it plays a tone of 8 cycles, and the count picks the half period from the table at TableTonesEating.
