I have just recently met one guy, who's supposedly been diagnosed after initial self diagnosis, who claims that he has NO sensory issues.
He may have sensory anomalies he is not aware of. One piece of research I once read measured ASD peoples' perception of sensory anomally and found approximately half reported such issues. Then they tested this same group using more objective means (such as reflex reactions) and found that the entire group were characterized by anomalies. The anomalies were detectable and measurable, but the individuals effected were not necessarily aware of them.
Another research group (using a very small sample size) tested visual acuity and found that every Autistic subject in the experiment had anomalous visual acuity. A research project with a much bigger sample found that the number of Autistic subjects in their sample group that did not have anomalous audio neuro-processing was below the margin of error (from recollection one subject in a group of around five hundred was not measured as having an anomally) predicted for the research.
I think people who have an ASD and no sensory processing anomally are rare, if they exist at all. The proportion who are aware of sensory anomally is probably much lower though.
