I had a similar problem starting Vegas Pro 12 under Windows 10 (and which ran well under Windows 8.1). I found that the problem was a conflict between two graphics cards installed: AMD R7 M270 and Intel HD Graphics Family. I disabled the Intel card in Device Settings (leaving the AMD card enabled) and Vegas starts up well.

Thanks for pointing me in the correct direction to resolve the issue.

Sorry, Richard. I can’t remember. (At the time, I was converting old VHS tapes to DVD format.) It appears that this problem has been fixed with later versions of Sony Vegas Platinum.

Thanks so much for that fix, Jon.

I noticed something else too. While you’re in the render dialog box, you can right click on the mouse to expand/collapse all the available formats.

I recently experienced this audio out of sync problem using Sony Vegas Platinum 9.0.

I imported a *.ts file generated by WinTV. (I am converting old VHS tapes to DVD format and inserting menus.) SVP imported the *.ts file well and on the SVP timeline, the audio/video were in sync. When I created the mpg/ac3 files for import to DVD Architect, the sync problem appeared. I tried different project/rendering specs without success. Finally, I downloaded (free) software that converted the *.ts file into a *.mpg (mpeg-2, I believe) file. When I imported this converted *.mpg file to SVP, the audio sync problem was clearly apparent on the timeline. To correct it, I stretched (in SVP) the audio tracks to match the video. I did this visually by picking a sharp noise with action toward the end of the video. The final result, in DVD Architect, was perfect.

I think the problem, in my case, arose from how SVP deals with *.ts files. I don’t know if this is the same problem described above in this thread but I thought that I would post this here in the event others have an audio sync problem.
