Once I render the file. It plays perfectly.

Increasing the volume does not really causes AV sync problem. Maybe in the preview it may cause some lag, whether the volume is modified or not. Computer resources might be the issue. Anyway, I think you dont have any problem at all since the rendered file is okay.
