Audio Channel Glitch - Audio Drops Out Randomly on Export

[Dubba_Scrubba]

Version 24.4.1 (Build 2)

Why would the exact same video source have audio play on left channel in track one, but in random places you have to change it to right channel for it to export properly?  

The audio in my sequence had exported fine at least twice before encountering my issue. I'm not sure what changed, but the audio starting dropping out in the same place.  I located the sound that was dropping out.  While I had used that same clip throughout the entire sequence only a portion was having the problem.  I fixed the issue by changing the audio channel from left to right while keeping it in track 1.  I only had to do that on the two clips that were dropping out.  The rest of the audio from the same source was fine with left channel on track 1. 

Here's what I did to eliminate any other potential cause of the problem:

• Cleared my cache through premiere and restarted the project.
• Manually deleted my cache through window explorer and restarted the project.
• Created a new project and copy and pasted all of the audio and video into a new sequence.
• Removed any audio effects.
• Deleted only the audio portion of the clip and pulled it down again from my raw.
• I had used simple After Effects comps in a couple of places in my project, so I exported those comps and removed the dynamic links in the project, so that After Effects wouldn't open while I was exporting.
• I lowered the bitrate.
• I changed the export audio options from mono to stereo.  This helped somewhat.  When I had exported in Mono, all audio tracks at this one point in the sequence dropped out.  When I exported in stereo the audio tracks that didn't come from the problem clip played.  This helped me narrow
• where the problem was coming from.
• Half of one clip in the sequence played fine, but the other half didn't, so I cut that track in the sequence where the audio dropped out in the export and then changed the channel from left to right.
•

If you can provide a project containing a sequence that references the problematic audio file (which we'd also need), as well as step-by-step instructions that reliably reproduce the problem, we'd be happy to pursue it further.
