Our living room television's (a Vizio) audio has been a problem for a while, with action scenes being too loud and dialogue being too quiet, sometimes to the point you couldn't make out what was being said. This resulted in constantly raising and lowering the volume in an attempt to manage the mess. Then we watched a couple episodes of Breaking Bad on the newer basement TV without that issue. That led me to believe there was either a hardware or software problem on the Visio and a little searching found the culprit. Volume Leveling was turned off, a feature that combats this very issue. I turned in on and it immediately solved the problem.
