You don't have the lines switched. The threads on the soft metal nuts are different, and even if you used adapters to switch the lines, the steering gear would try to go the opposite way you're turning the steering wheel.
A buzzing noise is common due to air trapped in the steering gear. Give it two or three days before you get concerned. If you can't wait that long for the air to work its way out, place the car with one front wheel up higher, like on a curb, then turn the steering wheel back and forth a few times. Do the same with the other front wheel up higher.
