Relive sound problem.

Hi, I have a problem with Relive. Video is perfectly fine but sound is messed up, at first it was just delayed for like 1 second but i synced it in a video editing program. Now it starts synced but with time, sound is like slowing down and not possible to sync. Here is a picture with the timeline, and as you can see the audio is not even reaching the end. I will also post this video so you can see yourself. Link to the video: CSGO Relive sound test - YouTube
