Limited audio exported in Premiere Pro CC 2020 project

[Matt Walsh]

Hi, hoping someone can help with an issue with audio exported in my Premiere Pro [CC 2020] project. 

I exported this project before with no issues with audio, but I've recently added background music to the project and tried exporting it again and the 'rendering required audio files' gets to 8%. I then export the project, once exported I play it in VLC and the audio plays for about 1 minute (without the background music) and then goes silent (the full project is 9+ mins).

I've tried clearing the media cache and just exporting it to mp3 but I'm facing the same issue with just one minute of audio exported. The audio in the project works fine, it's just when exporting there are issues.

what format is your audio?  I'd suggest converting everything to 48k 16 bit aiff see if that solves the problem.  although premiere will take almost any format you throw at it, some formats are problematic and should be avoided or converted...

Both audio formats are mp3. I'll try what you've suggested, thanks for your reply.
