P: Audio of AVCHD files in .MTS format with PCM audio does not play correctly - sounds like noise

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

It is happening with MTS files. Me and my colleagues use Windows 11 Enterprise.

Until this problem is fixed we will continue using the earlier version of the program.

After updating to version 25.3.2, I noticed a strange issue: when I insert any footage into the timeline, the audio levels suddenly peak (go into red), even though the source audio plays back normally outside the timeline. This seems to be a bug introduced in this version. Anyone else facing this?

We have the same issue.

When we play the audio in Premiere Pro latest version we can only hear distorted noise sound. Everything works fine when we use an earlier version of the program.

I made the mistake of upgrading Premiere Pro to 25.3 when I have a deadline looming.

After updating, the audio tracks of any imported MTS files from inside AVCHD bundles had been replaced with ear-blistering white noise.

I tried rebuilding my media cache and a few other tricks to fix it. Nothing worked, I had to regress to 25.2.3 to be able to continue working.

That is one thing you should not do is update with a deadline.

Best is to refert to prevvious build.

Make sure Default Input in the Audio Hardware in the Preferences is set to No Input.
