# Audio doesn't time correctly

So I made a small animation, and then I added in a simple "pow" sound in the Video Sequence editor. But when I started it, the sound played immediately. I rewound it even more, and the sound doesn't play until a couple frames before the file, and If I pause and play it over and over near where the audio is, it restarts and plays the sound over and over, until I get to the sound, and there it stops sounding at all. I don't know what could be causing this. The sound is not playing where it is supposed to play.

In the Timeline window -> playback, you must check "Audio Scrubbing" AND "AV-Sync". Does it resolves the problem ?
