I’ve had a major issue with fmod studio 2.02.22-20.02.26 on Ubuntu 24.04.1 where trying to build banks suddenly crashes fmod.
I managed to fix it once by completely removing fmod from my system, including all remaining folders I could find and by reinstalling. However I’m having the same issue again and I can’t fix it again.
The exact same project synchronized via git with git-lfs builds fine on other computers (Ubuntu 24.04.1, Windows). I did find however that trying to compress some ogg files also crashes fmod so that may be the issue?
Does FMOD Studio display the crash report dialog when crashing? If so, could you use it to report the crash using the same name and email address you use for the forums?
Can I get you to post a log from Studio where the issue occurs? You should be able to find the log at ~home/FMOD Studio/Logs
I got more info by running FMOD Studio from the terminal:

I suspect the issue is being caused by corrupted files, like you suggested, but it’s difficult to diagnose from just the logs. Could I get you to upload your Studio project, making sure you include all the assets assigned to the ambience bank, to the uploads section your FMOD User Profile for me to take a closer look at?
It’s also possible that source control may be interfering with files on disk in some way, e.g. locking files that are being written to, or writing to files/directories that should be excluded. Have the directories/files noted in our documentation on using source control with Studio been excluded/ignored?
In case that’s any help, I tried to repair the ogg files from the ambience folders as well as replacing them with wav or mp3 with no success.
We’re using git with git-lfs as version control, the FMOD Studio directory is at the root of or repo next to the unity project. The directories noted in documentation should have been excluded I think, although I initially forgot .cache, .user and .unsaved.
I included our gitignore to the upload so you can check for yourself.
After a bunch of testing on my end, I unfortunately haven’t been able to reproduce the issue you’re experiencing. The corrupt metadata file is benign, as it’s not being referenced anywhere else in the project, but it does point to there likely being some issue with how git-lfs is interacting with the local copy of the Studio project’s files.
Besides doing a completely fresh pull of the remote copy, I’d recommend doing the following and seeing whether they make any difference:
Ensure no files or directories are being erroneously locked by git, or have any weirdness with their R/W permissions, especially on existing built banks, assets, or the .cache directory
Completely delete any existing banks and try rebuilding them
Relocate the built bank and/or asset directories from where they’re currently located (in Edit → Preferences → Build/Assets respectively)
Relocate the entire Studio project
As an aside, I don’t seem to have your gitignore in the project upload, so if you could provide it or the relevant parts of it here, that’d be great.
Thank you for your suggestions, I tried it all suggestions but none of it worked.
I checked all assets files with lsof in case some were locked but it looks fine.
It turns out, I get the same issue when building banks from the fmod example project.

Edit: I upgraded to Ubuntu 24.10, the problem is still there
Given that none of my previous suggestions appeared to resolve the issue, it’s worth testing the lower-level functionality behind the bank building process to see whether the issue reproduces outside of Studio.
The problem line of code appears to just be making a call into fread from stdio.h, so could I get you to compile and run the following code from the “Reading from a Binary File” example from this page and see whether you run into any issues?
// C Program to Read from a
// binary file using fread()
#include <stdio.h>
#include <stdlib.h>
struct Num
{
int n1, n2;
};
// Driver code
int main()
{
int n;
struct Num obj;
FILE* fptr;
if ((fptr = fopen("temp.bin", "rb")) == NULL)
{
printf("Error! opening file");
// If file pointer will return NULL
// Program will exit.
exit(1);
}
// else it will return a pointer
// to the file.
for (n = 1; n < 10; ++n)
{
fread(&obj, sizeof(struct Num), 1, fptr);
printf("n1: %d\tn2: %d\n", obj.n1, obj.n2);
}
fclose(fptr);
return 0;
}
Thanks for testing - that likely rules out any dependency problems.
A few followup questions:
Was the FMOD Studio example project you were able to reproduce the issue with also checked into git?
You mentioned that the issue is present on 2.02.22 to 2.02.26 - does the issue not occur on 2.02.21? If it still does, can I get you to test which prior version of Studio, if any, it doesn’t occur in?
Can I get you to try building an FSB with some audio files using the standalone FMOD Soundbank Generator tool and see whether you run into any errors? The tool is the “fsbank” executable in the “bin” directory of the FMOD Engine installer
