Audio rendering issue during media export

Hi there,

I had a weird experience that the Quicktime video export appeared with audio levels varying quite a bit. In my timeline it all plays perfectly. I even rendered everything in the timeline and they are still playing perfect but when i export media the audio level variation happens. Also it starts the media export by re-rendering audio. If the audio is already rendered why does Premiere Pro have to re-render audio? How can I skip this step (i.e. using the format of audio in the timeline that is exactly same as targeted media export audio settings)? By the way I am using some VST plugins but I use plugins all the time and if it plays fine in the timeline why would Premiere Pro have problem with VST plugins during export?!!

And finally if this is a known bug? If so what version of Premiere Pro doesn't have this bug?

Thanks a lot,

Arya
