Why would animals have a wide range of vocalizations if they have no communication value?

Most higher order animals have a series of different vocalizations they make. Without serious study of a species, we may associate one simple sound with it. Horses whinny and neigh, elephants trumpet (because they can), pigs grunt. But scientists who record and study vocalizations of a species find they have a range of different sounds. Do you think the sounds are just letting off steam, or do they communicate something about how the animal feels that others of it’s kind can understand?
