Would something like the OP linked script be possible for Netflix (and the like)? I hate that the audio is so much quieter than the effects, and it feels insane that this isn't configurable, either at the hardware level (TV) or software level, let alone a scripted hack.

edit: maybe this "Reduced Loud Noises" language option https://news.ycombinator.com/item?id=33991712, and also apparently changing from 5.1 to stereo
