AVC Long G 25 footage audio hash

[huntson]

I have  PX270 camera and recently, while browsing Long G 25 footage recorded on this camera, audio after the first few seconds goes to all static or hash.  Consistenly I can play the first 2-3 seconds with clear audio and then it all goes to crap.  If I start later in the clip, the audio is all static/hash.  Attempting to transcode with Premiere Pro/Media Encoder results in the same sound in the output file.  When looking at the raw footage in FCP X however, it sounds fine.  Any ideas here?  Let me know what additional infomration I can provide.

FAQ: What information should I provide when asking a question

Per Ann Bens's recommendations I have the following ot add:

The footage is in a MXF container.  

I have tried this same setup on Premiere Pro 2020 and 2021 with the same issue.  I have tried on a MacBook and a MacPro 2013 running Mojave.  The MP has a Radeon RX 580.  All of this is happening without any capture cards, just looking at the footage on the computer monitor with built-in speakers.

Rendering engine selection has no affect on the issue.  No error messages are present.  I have reset preferences as well.  

Here is a link to an example of the source material: http://gofile.me/6rZyd/kTNuRksuh

Please post example video on forum, so we don't have to download unknown files.

The smallest file I have would not fit on this forum.  If I modify the file then you woudln't be looking at it as I am.  It's simply an .MXF, not a .zip file.  If you're uncomfortable, hopefully someone else will be.
