Bug: Changing an Imported Audio File Causes Disk Read Error for .cfa File

[Michael2345]

This appears to be a new bug introduced in roughly the past month or so. If you make a change to an audio file imported in your project, Premiere will throw the following error: "A disk error occurred while attempting to access the following file: **name_of_file.extension samplerate.cfa**"

This error prevents the audio file from playing anywhere in Premiere Pro.

1.  Version of the App: Adobe Premiere Pro (Beta) - Version 25.4.0 BETA (Build 25)
2.  Platform and OS Version: Windows 10 Pro - Version: 2009 - OS Build: 19045.5854
   
   
3. Steps to Reproduce Problem:
   a. Open Premiere Pro and open an existing project or create a new one.
   b. Import any audio file of any type (besides .wav).
   c. Premiere Pro will "conform" the audio file and create a .cfa file corresponding to that file.
   d. Save the project so the file will be loaded in the Project tab when the project is opened in the future.
   e. Close Premiere Pro to release the audio file and allow changes in other programs.
   f. Open the audio file in any audio editing program, make any change, and save the file.
   g. Open Premiere Pro and open the previous project.
   h. Premiere Pro will throw the following error in the Events tab: "A disk error occurred while attempting to access the following file: **name_of_file.extension samplerate.cfa"
   i. The audio file in question will no longer play in Premiere Pro.
   
   
4. Expected Result: If I make changes to an audio file outside of Premiere Pro, Premiere Pro should automatically update the corresponding .cfa file to match the updated file. This is how it worked in the past.
   Actual Result: Premiere throws the following:  "A disk error occurred while attempting to access the following file: **name_of_file.extension samplerate.cfa**"
   
   5. Workaround:
   a. Locate the aforementioned .cfa file corresponding to the audio file. This will either be in the directory of the audio file, or in the location specified in Preferences under Media Cache.
   b. Delete the .cfa file.
   c. Close and then open Premiere Pro.
   d. Premiere Pro will automatically conform the audio file again, creating a new, functioning .cfa file.
   e. The file will now play back correctly in Premiere Pro.

Hi @Michael2345 - Hi
Thanks for submitting your bug report. We need a few more details to try to help with the issue.

Do you see this issue in the Stable version of Premiere Pro version 25.2.3?

What audio program are you using to make changes?

Jamie,

Sorry for the delay in getting back to you.

I did some more testing, but realized this issue may not be on Adobe's end after all.

First off, I tested the issue in the stable version of Premiere (25.2.3 Build 4), and the issue occurred.

Then I realized that the bulk of my issues were occurring with .flac formatted audio files, and I remembered I'm using Autokroma Influx to import formats (like .flac and .mkv) that aren't supported natively by Premiere.

I experimented with natively supported audio formats like .aac and .mp3, and the issue did not occur.

This suggests that some recent change to Premiere has caused a compatibility issue for Influx and that the issue is on Autokroma's end to solve.

I apologize for sending the bug report to the wrong place, and thank you for looking into the issue. It appears we can mark this one as resolved.
