Have you tried a Vimeo preset from AME?
I have the same problem! I tried ALL different ways of fixing the issue but nothing works. The only thing to do is nest the sequence and nudge the audio track so it's back on beat.
I dont think that you will really get a problem while exporting in any of the given formats. But i would really like to check if the audio layer is exactly same as of the video. for eg - if my audio is 00:05:30 and my video is 00:05:20 , we might face issue with the sync.
We can try to put more black video to make it a match with the audio and then try to export.
Where do you have the media files , on a internal drive like c: or desktop? In case not , try to move the media files to desktop and then try to export.
Also instead of exporting the files to your 120GB SSD , try to export it on the desktop.
Hope it helps.
Have you tried other settings? For computer, 30P is generally best, unless you shot in 24.
