We all know the modern complaint: movie sound sucks now unless you have a high-end sound system. Frantically turning down the volume after turning it up to hear the dialogue only to need to turn it up again can be frustrating. Now, this doesn’t solve the underlying problem, but why not have a “Volume A” and “Volume B” you can easily set and toggle between with the simple press of a button?
How loud specific things are in comparison to other sounds is one of the things that a director dictates to set the mood for their movie. We all agree that it’s gone a bit far with most things nowadays, but having something be piercingly loud or eerily quiet can be used really well, and if everyone from Tommy Teenager to Granny Gertrude can alter these settings with a TV remote and zero knowledge on maybe what they’re even doing (“I thought I was changing the volume and now the people don’t talk anymore!”) it would greatly diminish the director’s ability to control that.
