How do i fix the audio delay? the audio is lagging behind the video. i have a vizio tv connected through hdmi arc. can i adjust a setting?

Both my new Hisense H9G TV and the Vizio sound bar have adjustable audio delay settings but, unfortunately, they both only worked one direction to further slow/delay the audio signal relative to the video signal. That was the wrong direction for me, and it sounds like for you too with audio lag. The solution for me was to plug my Fire TV stick (used for all viewing including live TV) directly into the sound bar "HDMI In" port instead of a TV port , then connect sound bar to the TV via HDMI-ARC ports. That eliminated the audio lag entirely and I can still control everything with my Fire TV remote alone. Another thing to try is using optical connection from TV to sound bar and set the TV output to PCM, which might help reduce/eliminate lag. Hopefully Vizio comes up with a firmware fix for this or better troubleshooting tips on their support site, otherwise retailers may get a bunch of these back from people without the knowledge or patience to try different things. That said - I love my sound bar and bought another for a second TV in another room.

What if your tv doesn't have earc hdmi?

If your TV doesn't have eARC port, then you will not be able to use the eARC port of the soundbar to enjoy audio formats higher than DD/DTS 5.1, unless you get the following model, it will let you use the eARC port of the soundbar to extract HDMI audio from all HDMI sources, such as Fire TV, Roku, Chromecast, Apple TV, blu-ray player, etc. https://www.amazon.com/gp/product/B097NXXDG6 Get this UHDe4x1 eARC audio extractor for your eARC soundbar.
