mp3 files error FSBTool ERROR: Internal error from FMOD sub-system.

[YianC]

After I updated to Unity 2022.3.18, some mp3 files had errors.

The message is as follows
FSBTool ERROR: Internal error from FMOD sub-system.
FSBTool ERROR: Internal error from FMOD sub-system.
(Filename: ./Modules/AssetPipelineEditor/Public/AudioImporter.cpp Line: 1062)

Does anyone have the same problem?

Yes, it’s a known regression. I’ve patched it so it should be available on the next update.

Here’s an earlier discussion about it on the forum:

FSBTool Error in 2022.3.17

Updated my project from 2022.3.12 to 2022.3.17. When reimporting all of my game's music, about 6 out of 30 mp3 files failed to import. The error message was "FSBTool ERROR: Internal error from FMOD sub-system." I note in the release notes for 2022.3.17 that FSBTool was updated and I can see a new executable compared to 2022.3.12. When I manually place the old FSBTool from .12 back in place, I can reimport the mp3's without issue. So it seems something broke that some mp3s/files expose? I've lo…

I’ve got the same issue for Unity 2022.3.19. Any estimate of when we can expect a fix? Thanks.

@ - you keep breaking LTS versions, THIS.HAS.TO.STOP!

This issue for example, you say it should be fixed in the next version, but the next version is out and it is still present. For that matter your comment could be taken as for version 2022.3.19 or 2022.4.X or 2023.X.X please be more specific.

Do you have structured testing, both programmatic AND human? It does not seem that way from the issues I have been reading about.

Hey folks,

The fix is currently on the bench, pending for QA. As you might be aware, the company is “going through a phase” right now, and this part of the machine is currently impacted.
The issue is that there was an accidentally incomplete backport on a complicated MPEG codec fix. I am sorry that it’s taking so long, but we should get there soon.

On a side note, it is super relevant that you voice your concerns, and it helps us build a case about what should be improved in our media stack. Codecs and media framework is one of our top priorities.

We do have a testing infrastructure, and while it’s not perfect it catches a lot of small errors! The human side for testing media quality over all platforms is a complicated one, and it’s practically impossible to do all manuals tests for all bugs for all platforms. In this case, we’re incrementally building a library of files known to have failed to test for regressions in the future.

The issuetracker says it is fixed in 2022.3.21, so we need somewhere around 2 weeks to a month.

Updated from 2022.3.20 to 2022.3.23, but the issue still occurs.

Known issue with Unity 2022.3.18 and mp3s. Try re-encoding the mp3s with a different tool (like Audacity). Otherwise, wait for a Unity update or downgrade to a previous version (2022.3.17 might work). Good luck!
