2.0 Soundbar Will Not Connect To Vizio App

Hello,

I recently bought and installed a Vizio 2.0 Soundbar for my living room TV. Since installing, the sound quality sounds very muddy and echo-y in the apartment to the point it’s difficult to understand words being said), almost worse than how it sounds with just the normal TV speakers. I am trying to link/pair it with the Vizio app so I can adjust its audio settings/EQ to see if I can improve the sound quality, but as it stands the app (or soundbar) absolutely refuses to allow any sort of connection. I have followed every step I have seen on the internet with people having the same problems I am having, to no avail. Can anyone offer assistance on what to do? My TV does not allow control over the audio settings while using a sound bar, so using the Vizio app and/or finding a way to “tune” the soundbar itself it my only option.

Thanks!
