Sound cutting out in my exported video

If you're using external plugins for audio track effects, make sure your licenses are updated. I couldn't for the life of me figure out what was going on until I moved everything to an unedited track and exported everything, then no audio dropout. 

Demo mode on certain plugins don't watermark, they just cut out every 10 seconds. May not be the same problem/solution for everyone, but worth looking into if you're experiencing these issues.

I have no clue how this works but i just extended the audio (i was using a song) and then put cut it back to how i originaly had the audio and this seemed to work, please let me know if this worked for anyone else

 Not sure if this is the same problem everyone else is having, but out of the blue a video clip I had been editing with lost a portion of the audio in the timeline only when I exported. It worked fine in previous exports, but something changed.  Clip main audio was left channel in track one. I found that if I went to where the audio was dropping out, cut the clip and change the audio channel to right channel and kept everything else the same, it worked. I have never in my life seen anything like this and I've been editing for about 20 years. I cleared the cache through premiere, I manually cleared the cache in my file explorer, I copy pasted the sequence into a new sequence in a new project, I did everything I could think of to make it work and the only thing that worked was changing the channel on the part of the audio that is cutting out. Hope this helps. 

March 3rd 2023, My fix was to Ctrl+A (copy everything) make a new sequence and paste it there, Took 10 seconds and didnt lose any work.

Ok so finally after awhile experimenting I have found a solution that has worked for myself. The clip that your having issues with the Audio on the timeline lock the Video, delete that part of the Audio and grab just the Audio from that clip and drop it under the clip and hopefully this will work for you. This issue definitely needs to be fixed after all these years. 

End of Feb 2023 and still having this issue. Had to export my audio and then bring it back into the video for it to work.

Do Adobe even bother to look at these threads to see issues going on with their software?

Suuuuuper late to the party but I have to contribute because I just spent hours trying to fix this. If you lock the audio track that keeps cutting out before you export, it will solve the problem. Don't know why it works but it does.

Have you tried resetting preferences and/or reseting your workspace?
Reset your preferences by holding shift+alt (or option) when you launch Premiere

January 2023. When is Adobe going to fix this major bug?

More than 2 years later, I am still dealing with this issue on a regular basis.  I don't trust my exports anymore, I have to watch them fully through before uploading to youtube which is the usual place I do a last watch before publishing.
