music but no dialogue

Dec 30, 2018
Have a Vizio 4k tv and a Vizio 2 channel sound bar and a Sony 4k Blu-ray player and get music but no dialogue when I play a movie. Have tried just about everything. Any idea what it might be?
Is playing surround with center channel, except either your TV doesn't know you have a stereo-only soundbar, or the soundbar is not using the proper surround decoder. Surround SB would typically have MODES, toggle through it see what happens, nothing is gonna blow up.
