I’m encountering a crash in Unity, detailed in the dmp file with this error: `Unhandled exception at 0x000001807F3E2F51 in crash.dmp: 0xC000001D: Illegal Instruction.` It consistently happens when an audio event is triggered, but the specific event varies each session. I have a few questions: 1. Are there known issues causing crashes with FMOD for Unity 2.02.20? 2. Is there an FMOD Symbol Server available for debugging? 3. If a symbol server isn’t available, can I get PDB files for these DLLs? - `fmodstudio.dll` - `fmodstudioL.dll` - `resonanceaudio.dll` All are located in `Assets\Plugins\FMOD\platforms\win\lib\x86_64`. Appreciate any guidance you can provide! ---

Hi Denver, I have uploaded debug symbols for FMOD For Unity 2.02.20 to the [uploads section](https://www.fmod.com/profile#uploads) of your user profile page. Kind regards, Morgan ---

@morgan_fmod thank you for sharing the symbols. Using those, I can now see the full callstacks. It seems like others have not reported this issue so I’m a bit perplexed what about our project could be the cause. The relevant threads to FMOD are ```auto ID Category Name Location --------------------------------------------------------------------------------------------------------- 8128 Worker Thread Win64 Thread [Inline Frame] fmodstudio.dll!FMOD::OutputWASAPI::mixerThread 10456 Main Thread Main Thread fmodstudio.dll!FMOD_OS_CriticalSection_Enter 8808 Worker Thread Win64 Thread fmodstudio.dll!FMOD_OS_Semaphore_Wait 3008 Worker Thread Win64 Thread fmodstudio.dll!FMOD_OS_Semaphore_Wait 8908 Worker Thread Win64 Thread fmodstudio.dll!FMOD_OS_Semaphore_Wait 12164 Worker Thread Win64 Thread fmodstudio.dll!FMOD_OS_Time_Sleep 12512 Worker Thread Win64 Thread fmodstudio.dll!FMOD_OS_Time_Sleep ``` Of these, `8128` and `10456` seem like the only two that could have resource contention. ```auto 10456 Callstack --------------- [External Code] fmodstudio.dll!FMOD_OS_CriticalSection_Enter(FMOD_OS_CRITICALSECTION * crit) Line 780 C++ fmodstudio.dll!FMOD::AsyncManager::enterCommandQueueLock() Line 253 C++ fmodstudio.dll!FMOD::AsyncCommandLockScope::enterLock(FMOD::RuntimeAPI::Manager * manager) Line 15 C++ fmodstudio.dll!FMOD::AsyncManager::gameUpdate() Line 194 C++ Inline Frame] fmodstudio.dll!FMOD::Studio::system_update(FMOD::Studio::System *) Line 1515 C++ fmodstudio.dll!FMOD::Studio::System::update() Line 4714 C++ ``` ```auto 8128 Callstack -------------- [External Code] [Inline Frame] fmodstudio.dll!FMOD::OutputWASAPI::mixerThread() Line 601 C++ fmodstudio.dll!FMOD::mixerCallback(FMOD_OUTPUT_STATE * output) Line 1040 C++ fmodstudio.dll!FMOD::Thread::callback(void * data) Line 142 C++ fmodstudio.dll!FMOD_OS_Thread_Callback(void * param) Line 619 C++ fmodstudio.dll!thread_start(void * const parameter) Line 97 C++ [External Code] ``` Here are the full set of callstacks in case you want to see this.
