As of now, I am working on 2 games with Godot 3.3... and there is an audio lag for both games when I compile it to HTML5. I have researched this issue on the internet and came across numerous posts where people have complained about this. I have yet to see a fix or a workaround or any effort from the developers to deal with it. As much as I love the Godot game engine and working in it's environment, there are quite a few things that can get frustrating during the process. This is definitely one of them. Obviously this is still an ongoing issue, so can someone enlighten me as to how they deal with the lag. There is also a an audio quality issue going on as well.
If you're interested in seeing exactly what I'm dealing with here, then check out one of my games below:
