Thanks for letting us know about this. Unfortunately I have been unable to reproduce the issue here. Can you share any more information to help us resolve it?

  • What Linux distribution are you using?
  • What version of FMOD are you using?
  • Do you have libfmodstudio.so and libfmodstudioL.so in the Assets/Plugins/FMOD/lib/linux/x86_64/ folder?


Regolith Linux.
I believe it is 2.01.00.

Thanks for the additional information. I have just tested with FMOD 2.01 on Regolith Linux, and unfortunately I am still unable to reproduce the issue. Do you have any other plugins installed? Does this issue occur in a new project with nothing but FMOD for Unity installed?


Yes an empty Unity project crashes on my system, no packages no assets, but the imported FMOD causes a crash on import, and then cannot open the project. If you could provide your apt list --installed that could aid in finding a package I could possibly be lacking. Aside from missing possilbe packages I’m at a loss why this happens.

OK, the apt list --installed output is at https://pastebin.com/LFaY4g2B .

I tested both in a VM and on a live disk, both worked but once I reinstalled my distro it did not. So it does seem my system is causing some incompatibillity.

Is there anything useful in the editor log? Log file locations are documented at https://docs.unity3d.com/Manual/LogFiles.html.
