Got a "Wall Job" at the dealer this weekend

My '08 Prius suffers from the brake noise actuator problem, which causes it to make barking sounds when it's stopped and in "ready" mode. The stereo also makes a high pitched sound when I connect my Sirius radio to the Aux port.

After being annoyed by these noises for months, I decided to take it to the dealer early Saturday morning. I explained to the service rep. what the problem was and told him about the TSB's that have been issued for these exact problems. The service tech said "no problem, we'll get it taken care of", so I left the car there for the rest of the day.

Half an hour before closing, the service tech called to tell me that my car is ready and he is leaving the keys with sales. Once I got there, the receptionist had to go look for my keys in the service shop, then I had to go to the back (where they keep the cars they are working on) and look for my Prius, which was parked next to the wall. I noticed that nothing inside had been disturbed. When I looked at the work order, they had the following resolutions:
Brake noise when in "ready" mode: Brake noise is normal. Nothing wrong.
Noise from Aux. port: The noise is due to aftermarket wiring. (This would be the audio cable from my Sirius going into the Aux. port).

So, what the heck? I know this Prius makes more noise than my old Classic Prius, but that loud sound it makes can't possibly be considered normal. It almost sounds like I'm tapping on the horn.
