Avidemux has an audio sync feature right on the main page, but you need to do it manually via trial and error. ie try various iterations of 50, 100, 150, etc ... (or other values) changing the start time of the audio vs the video.

That assumes the desync is consistent. If the desync is variable through out the video it is much much more difficult to try fix (and imho in that case not worth the effort).
