FIX the bug of audio missing from export

[davide.bonaldo]

When exporting a video sequence premiere randomly leaves out part of the audio. Those part were not muted, but in the same channel and of the same kind of other parts exported fine, not even cut: so for instance you have a talker that randomly get the voice silent.
This is a big reliability issue, because there is no correspondence of what you have on timeline and what you are going to have on final export. This happens on different machines and happened also with previous versions of Premiere different from this one at moment of writing 15.4.1 (build 4).
The only reliably working workaround has been export only the single audio channels in wave files and then import it back into the timeline, that is time consuming and unacceptable for a professional software.

FOLLOW UP: When exporting the culprit for me losing audio on export is a huge temp files. My drive was hitting its cap despite having 80+ gb of free space on that drive. After moving my temp folder to a larger drive the issue stopped.

Please watch your drive as you are exporting your video and see if you are topping out, hitting capacity. This was the main reason my issue persisted and there was little to no indication in the error logs that it was due to temp file sizes.

The error would often read "insufficient storage" but sometimes would still export while dumping the audio when the temp storage ran out.

If you are on Windows, I've linked the way to move temp files to a new drive below. I hope this helps

What I did is I exported the audio to wav 
then replace the audio from my timeline.

I have the same issue. Single, very short files are simply missing. Other files on the same track work just fine. I have removed the from the sequence and added them again. The issue is still there.

It's not fixed. I'm fully updated on all versions and it's still doing it. Nothing is working.

It's still not fixed Adobe!!!! Such a mess with this Apps.

The issue persists. Randomly missing audio in 1 hour movie at least twice for 20-30 seconds.

My guess is that it deals with the great-most-buggy "Dynamic-forget-all-Links-Server". Randomly it looses connection to files while rendering and this is why you cannot detect the source clip. It just happnes randomly if the link server is down (for what ever reason) for seconds while rendering.

Such a messs.

The "out of storage" theory sounds plausible. It stands to reason that Premiere Pro requires substantial temporary space to pre-render exports. This aligns with my experience, as I encountered the issue on larger-than-usual projects. At the time, I had approximately 50-70 GB of free space on the Windows drive — which could have been insufficient. But it's still speculation from my end.

I took a break from work, but if anyone else finds that it does indeed help to either free up more space, or to move the Windows temp folder to another drive with more space, please report your findings here. Your feedback is much appreciated. Adobe won't take this seriously, so all we have is each other.

Actually it was the buggy h.264 compression of Premiere Pro, as I read through different other sources and combined the findings there.

So I changed my output video to AppleProRes 422 Proxy (which gives nearly the size of a proper H.264 compression) and to a Qicktime .mov format instead of .mp4 and it worked out with all audio from all clips included ...

STILL HAPPENING! ISSUE NOT FIXED> I can't even export the audio without missing parts. Is there a new workaround?  HELP!!
