Hello FMOD, There’s a small problem when building for Switch. (Unity 2019.3.3f1 + FMOD Integration 2.01.01) There’s a linker error: **undefined reference to ‘FMOD5\_Thread\_SetAttributes’**. I’ve looked in libfmodstudiounityplugin.a and it doesn’t contain that symbol. I worked around it by excluding the usage of that symbol for Switch. Just letting you know about the issue. Cheers! ---

Thanks for the report, can I get you to double check the version you had issues with? We fixed an issue concerning the Thread\_SetAttributes symbol for Switch but that fix should be in 2.01.01 (it was broken in 2.01.00). ---

I did, and you are right. I apologize. I actually had 2.00.09. Thank you!
