Question Why does Sony Vegas 15 mix up my audio?

[biankaa]

So i have a problem with rendering (i think). So i use Sony Vegas and and wanted to render an mp4. Its mostly just edited music with a gif in the background. After i rendered the mp4 and listened to it, somehow the length of the video matches but the audio is different. Like the audio ends somewhere in the middle of the original music i edited and played in Sony Vegas. I rendered it again and had the same problem.

I have lots of issues with Vegas Pro audio in many versions since 12 and through 17. I solve that issue by always converting my audio to .flac format instead of .wav. Corrects the jumbled audio issues that .wav files seem to cause.
