Did you try to just plug your device into your tv and play the audio out from TV speaker to verify the delay. If the delay still exists, it means it could be your content devices or the hdmi cable attached to it is bad. Otherwise, it means there is something not right about the soundbar to work well with your setup.
Yes, the video is ahead of the audio by 200ms when using an external device, connected via HDMI or Optical. This was verified using the TV speakers and soundbars connected to Xbox One X and PS4 Pro and using their YouTube apps to play an audio sync test. They are connected via different HDMI cables and in different ports on the TV. The results are the same.
For testing purposes, I can’t verify the exact delay on DirecTV because there is no way to launch YouTube.
When launching YouTube on Roku TV and using the internal speakers, the delay is consistently testing at 0ms. Though I can’t be sure that it wouldn’t fall out of sync over time.
So as I said, those sound bars only offered the option to delay the audio even more—so the 200ms delay behind the video would be increased to up to 500ms using the AV Delay options. There was nothing to lessen the delay on the audio.
Do you understand what I mean? It’s a pain to explain and I feel like I’m making it confusing.
Also, I don’t have a sound bar anymore. All of the testing is being done using the built-in TV speakers.
