I don't know if anyone else has experienced this and it's not a huge issue, it just makes me curious as to why it's happening.

Basically, when I play a video whether it be through PreShow Experience (Kodi) or Plex the audio takes a second or two to kick in. It's not a smooth transition when going through the sequences because you see the video playing and then all of the sudden the audio kicks in which is incredibly annoying. The audio isn't out of sync with the video, it just cuts out in the beginning of every single video I play during a PreShow Experience sequence. This will happen if I pause and unpause a video as well.

Like I said, it's not a deal breaker, it's just incredibly annoying and if there's an easy fix then I'm all ears!

Can you describe your setup?  Do you have arc enabled?

It plugs into a sound bar (Samsung Q990B) and that plugs into my TV. I don't use the ARC port on my TV though. My TV is an LG 55 inch, but I don't know the specific model.

What is your sound mode on the sound bar?  Try is at standard if it is set to something else.  

If that doesn't work, try hooking up your player to your TV and then have that plug into the sound bar.
