It seems sense that you would choose to use Edge for Netflix in order to take advantage of 1080p streaming, as other browsers like Firefox only offer 720p. Regretfully, Equaliser APO (1.1.1) doesn't appear to function well with Netflix on Edge in Windows 10. This could be due to the browser's audio processing limits or the way it handles DRM content. It's unpleasant to be limited in this way, but you can get around it by investigating other platforms that give you more control over audio settings...
