\textit{Playback does not keep up so you hear the audio ahead of the video.}
When this occurs, it most likely means that there is not enough CPU power to keep up. You can go into \texttt{Settings $\rightarrow$ Preferences, Playback} tab and uncheck \textit{Play every frame}. Not playing every frame means that as it plays, if it can not keep up with doing all it has to do to change the frame into a vframe and then draw it, the program just notes that it is falling behind so skips frames to catch back up. This does not affect rendering. A different solution is to use Background Rendering as described in section \ref{sec:background_rendering}.
