Hello!  
We recently upgraded to fmod 1.06 for our Unity iOS game. Building in unity is fine, but when running in Xcode it shows this:

```
Undefined symbols for architecture armv7:
  "_FMOD_Studio_CommandReplay_Seek", referenced from:
      RegisterMonoModules() in RegisterMonoModules.o
     (maybe you meant: _FMOD_Studio_CommandReplay_SeekToTime, _FMOD_Studio_CommandReplay_SeekToCommand )
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

```

I have no idea where to start looking. Can you help?  
Thanks in advance.

We’re experiencing exactly the same with the latest Unity and the latest FMOD.

Replace assets\plugins\fmod\wrapper\fmod\_studio.cs with this [http://fmod.org/files/fmod\_studio.cs](http://fmod.org/files/fmod_studio.cs)
