I've discovered that it's nearly impossible to line a sound clip up accurately to a frame using the sound window. The playhead does not seem to correspond to tha actual position of the sound clip. The issue seems related to the sound window zoom.
Placing a sound clip precisely at the play head, using scrubbing to accurately select the desired frame, will only result in the correct timing of the sound clip if tbe sound window is at a very specific zoom setting. At all other zoom settings, the sound clip will not be correctly aligned during playback.
