Using the latest version of PP (25.3.0) I was working on a project containing MTS video files, and all of a sudden the next day I opened up the project, and all of the audio tracks of the clips had max volume static (and nothing else). It had been working for several days. In the audio track timeline, it displays as just a solid bar, rather than a typical bar with variying levels as you'd expect (see attached). It is like this in the editor, and also if you export the video.
I messed with this for hours, including contacting Adobe Support Chat for about an hour. They weren't able to help. They left me with suggesting that I make sure all of my Windows updates were in place. I did that and still nothing. I messed with my video card drivers - making sure they were on the latest version, etc. I downloaded the AC3/AC4 codecs from the other Adobe post talking about MTS files not working in the latest version of Windows - that didn't help. I also have cleared cache several times, and I tried re-insatlling the latest version of PP.
If you open the files by themselves in Windows, they are fine. The audio is normal. They work fine in MS Clipchamp. They also work fine an older version of Premiere Pro that I downloaded (24.6.5). So, theoretically, I could start over and do this in 24.6.5, but I'd prefer to continue working in the latest version. I'm sure this is codec related or something, but I have hit a brick wall.
Has anyone else had this specific issue, and have you found a solution? Thanks
