FIX the bug of audio missing from export

It doesn’t matter btw if you export in hevc or prores hq, the random audio drop just happens. I rebooted and rebuilt my cache. and it still drops out in one random place 4 minutes into a 26 min video. This is bananas. Been absolutely killing me. I’m already doing more editing in Davinci, though it has it’s own media management woes. 

It still is an issue. Just got made aware from a fan that on my video files randomly audio parts are missing. In files from 1 to 3 hours it often cuts off after 20-40 minutes.
For a paid product, this is rediculous that this problem still exists after years. It makes the entire product unusable.

Adobe, when do you plan to get this fixed?

:: THIS WORKED FOR ME ::
After trying many things, I exchanded the audio tracks from tracks 3 and 4 (moved the one that was on track 3 to track 4, and the one that was on track 4 to track 3)... and so found that track 4 was the one that was missing on the exports. So, I deleted track 4, added a new track, put the audio file there and worked.
Hope this works for someone else.

This is still a problem--BUT! I have discovered a potential fix. Or rather, here is what worked for me.

This seems to be YET ANOTHER issue tied to Premiere not exporting correctly when using proxies. I am having this issue (v25.1, 2022 mac book pro). Nothing on this thread fixed the problem for me. I was freaking out because the issue had me way past deadline on a project (thanks, adobe!).

Finally, I toggled off the proxies just for sh!ts and giggles and, bingo-bango, all my audio was in place. I also toggled them back on and exported again just as an experiment...audio was missing again. Toggled the proxies off and re-exported...fixed again. 

Bottom line...now you have to turn off the proxies before you export anything, whether it's stills or the whole video. 

Hope this helps!

This is still happening to me in 2025. And we pay for a program like this, it's really a joke...

This just happened to me. I copied and pasted my sequence into a new sequence, and successfull reexported. 

This is still an issue as of February 2025.  Premiere 25.1 on a new installation of Windows 11.  Plenty of system resources and everything is updated.  When I import projects from After Effects (also v25.1) sometimes the audio doesn't even import with the project.  When it does import, it will sometimes export out of Premiere to video and sometimes it won't.  It seems quite random.  Sometimes I can reimport the AE files and it'll work, but sometimes it won't.  I've tried all sorts of workarounds (cache management, saving AE files as new files, etc.) but nothing consistently works.  This is causing quite a bit of frustration and lost time.

Hi, it's 2025 and the issue is still there.

Context:

I use Adobe Premiere Pro 2024 and 2025 (version 25.1.0 (Build73)).

In my case, every time that I export there are specific missing parts, sentences exactly.

I tried the method "render and replace", it works great for all the parts that already provided sound but not for the one with no sound.

For that specific sentence (that has no sound on the export) after render it, it replaced it with 0 volume (no sound).

I realized that Channels 1 and 3 were needed because channels 2 and 4 had no sound.

Workaround:

• I tried rendering and replacing, changing the sequence with a new one, changing the track from 1-2 to 5-6, and trying to export only the sound, but the same issue appeared over and over.
• I use a proxy for all my long materials. So I used the proxy sound for that specific sentence. And it worked. (but it took some time because there were a lot of missing parts...)
• I will try to convert all my materials from the start (even if it takes some time), and see if it's going to have this issue anymore. I will repost it if it still appears.

I am sure that someone from Adobe understands better than me.

I realized from my issue, that Adobe Premiere exports another Channel for that specific sentence (and not the one assigned by me).

It never happened with Channels 1 and 2.

So the issue appears to be (at least in my case, where the sound disappears only on specific sentences, and every time the same parts are missing) - that Adobe Premiere mistakes interpretation of the Channel assigned (it takes Channels 2 or 4).

I hope to solve this issue if I convert all my materials from the start.

Unfortunately, it doesn't work so great (takes a lot of time) for films and long-long materials.

It still makes the same issue only from time to time.

For long materials this is an issue because of the time to recheck if anything is missing.
