I was watching "The Grand Tour" on Amazon Prime and the last two episodes seem to either have terrible audio mixing or some different kind of encoding that part of my system does not like. Right from the start, the music sounds a bit distorted and then when the hosts come on stage the audience clapping sounds absolutely terrible. I watch everything through a Roku stick that is about 5 years old and I am wondering if that is the issue. I have a brand new Denon receiver and Andrew Jones speakers (no center). I have also noticed that if I watch anything on Netflix I have to change the audio from "English 5.1" to "English" or the highs sound distorted or over modulated. Has anyone else noticed this? Thank you in advance, because if I have to mess with any audio setting mid-movie, my wife might kill me.
