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:
- Are there known issues causing crashes with FMOD for Unity 2.02.20?
- Is there an FMOD Symbol Server available for debugging?
- If a symbol server isn’t available, can I get PDB files for these DLLs?
fmodstudio.dllfmodstudioL.dllresonanceaudio.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 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.

Of these, 8128 and 10456 seem like the only two that could have resource contention.
