I'm afraid that I'm out of my depth here, particularly as I can't remember seeing Aspergillosis in a dogs' ear. It tends to prefer the respiratory system, particularly around the nose or sinuses, although there are anatomical links between the two and I understand from Merick's veterinary Manual that Aspergillosis can become involved in Otitis Externa (external ear disease). You sound to be looking for a 'yes' or 'no' answer for your dogs' particular case - perhaps this could be insurance-related? - and of course, the best person to provide that information would be the vet in charge, who has examined the dog thus far. Usually vets like to be asked questions and if they can't answer them, perhaps the further inestigations you mention would be in order.
