Tires with toe in/out issue do not make noise on the road. Your tires just wear out unevenly and quicker.

A vehicle that has absolutely no alignment, suspension, or tire pressure issues, and that is driven conservatively will still develop a heel-and-toe tire wear pattern due to the dynamics of the tire tread blocks when they make contact with the pavement. And the greater the heel-and-toe wear, the greater the tire noise level.
The alignment and suspension check was suggested simply to make sure everything was assembled within spec by the manufacturer.

After rotating the tires in an almost X (swapped rears, then front to back) pattern, noise disappeared. So, I have a tire shop that handles all of my racing needs located right outside of my neighborhood. While they were fixing the nail I had in the driver front that I discovered while rotating, I had them check the alignment. They did notice some slight wear on the right rear (was upfront) prior to aligning. Once on the lift, the toe setting was off (toe out) on both sides. Not much but definitely out of spec. The rest of the alignment checked fine along with the front suspension. They took care of it for me and looks like the tire in question will be ok. I'll just leave it in the back for now. Now I did fail to mention I have a Boss 302 suspension on the car but I'm a little shocked how little the change is between the two would cause the toe to go out. I lowered my '10 with FRPP P springs and my toe was ok. Different car different results I guess. All is well and she drives like a champ once again.
