... it would be nice to have HW that keeps the sound levels ALL at the SAME levels. I still hate it when I'm watching a show and it cuts to an ad and the sound comes blaring out of the speakers during the ad.
With the passage of the Commercial Advertisement Loudness Mitigation Act (CALM) into law on on December 15, 2010, networks who are still practicing or allowing this are now breaking the law.
The FCC is charged with enforcing this law, so file a complaint if you are experiencing this.
