Use
the A/V Sync button in the Player Setup menu to force audio sync
with video, even in cases where you play clips at a different framerate:
With
A/V Sync enabled, audio and video play at the framerate set in the
FPS field.
With
A/V Sync disabled, video plays at the framerate set in the FPS field,
but audio plays at the project's framerate. The project's framerate appears
on the EditDesk in the Format menu.
