I am experiencing a hard crash in the Unity Editor on Kubuntu when loading my main game scene. I tried reproducing in a minimal scene (just loading/playing a single sound in an empty scene) and that works fine. I am very certain that it is FMOD that causes the crash, since uncommenting all play calls will make the game run fine. I suspect it might be some sort a threading issue, since it only happens when there are multiple sound sources and triggers set up and also because of the NULL critical section errors.
These errors were typically seen in the log:
[FMOD] FMOD_OS_Thread_Create : pthread_create returned 22
[FMOD] DSP::setParameterData(-2147483648, 0x77dbf23b7630, 431292) returned ERR_INTERNAL for DSP (0x77DBDC1D78C0).
[FMOD] remove : assertion: ‘cont’ failed
[FMOD] FMOD_OS_CriticalSection_Enter : cannot enter NULL critical section
Environment:
OS: Kubuntu 25.10
Unity Version: 6000.3.7f1, 6000.3.9f1 and 6000.3.10f1
FMOD Integration Version: 2.03.06 and 2.03.12
I can provide a more detailed log if needed. As stated it’s hard to provide a minimal reproduction case, since it does not happen in an empty scene. I have tried almost removing all content of my main scene and it still crashes out when triggering a / enough sounds. I have also tried multiple different levels/scenes, just to make sure that it was not the specific scene that was broken. The bug has been reproduced on two different machines (both running kubuntu) and with 3 different sound cards. It works fine on Windows (exactly the same project), so it does not seem to be project specific, but rather OS+Fmod specific.
