5:1 DVD sound conversion

Does anyone know of a sound bar device that converts the 5:1 sound increasingly and exclusively encoded on a DVD to normal stereo so that the dialog can be clearly heard? My only option is to use subtitles to understand dialog.

That is usually a setting in the DVD player set up menu.

Hlg In the DVD set up menu - increasingly not amenable to 2.1 and each DVD seems to have its own idiosyncratic menu. Is there a speaker device like a sound bar that can change a 5.1 soundtrack to a pseudo 2.1?
