Some Audio Tracks Not Exporting

[izhebehi]

When exporting my video from Premiere Pro, either directly or with Media Encoder, one of five audio tracks is missing. This audio track contains short clips of dialogue which were recorded in the same way as those that are in another audio track.

I read this topic (https://community.adobe.com/t5/premiere-pro/some-audio-tracks-not-exporting/td-p/11356925) and I seem to be having the same issue. However, I've converted my mp3 files to wavs, with matching 48k Hz sample rate for the audio files and in the sequence settings with no change. I've also tried the basics of emptying the media cache and removing preferences.

I've been working on this project for a while, having previously exported the video with all the audio tracks fine. I can't think of any changes I made between the previous export and now (no plugins, updates etc).

Does anyone know how this could be fixed? Please let me know if you need further details about any part of the project.

Update: I have tried a fresh install of Premiere Pro, and exporting the file using multiple different settings. Exporting only audio, and soloing the track in question still don't include it in the export.
Any help is very much appreciated as this project is time-sensitive.

Make new project and import old one: see how that goes.

I tried importing the sequence into an empty project like you said, but now when I preview it the same audio track is missing as when I exported it.

I ended up creating a fresh audio track and duplicated the audio clips into this new track, along with the track mixing effects. Functionally this track is identical but somehow all the audio is exporting correctly now.

Hi there, could you please explain how you managed to resolve this?

I believe to be having the same issue as you although am quite new to Premiere Pro, so can't work out what I'm doing wrong.

Hi, sorry for not responding sooner.

What I ended up doing to fix the issue was to create a new, blank audio track. I then duplicated all the sounds from the faulty audio track and put them into the new, blank one. I don't know why this worked, but it seemed to be fine after that - I even deleted the original audio track that was having issues.

Hope that helps!
