Urutum, I just downloaded and went through the tutorial and the video and audio is perfectly in sync for all parts so just re-download the part where the audio was off, I'm fairly sure that it was part 6. I remember speaking to you on the forum almost a year ago when this tutoral went out and if you downloaded it then the initial lighting part did have this problem, I caught it not too long after we put it out and fixed it. Again sorry, I've sent you a pm so check your messages
