@MonkeyBomb Hey. Well it seems there was an issue with volume but we haven’t hear of issues with syncing. Would you mind sharing your pencil2d project file so the developers can inspect it?
I know there’s been issues with sound syncing before but those were mostly fixed (or at least we haven’t had complaints until now)
If the problem keeps up while the devs take a look at your file I sincerely suggest using a video editor to sync up the sound. There are free alternatives that are easy to use like http://openshot.org, http://shotcut.org or https://kdenlive.org/en/
Just load the current video you exported into one of those and move the sound track to sync up like you wanted to and re-export the video form the video editor.
