I’m using Fmod Designer, an old version of FMOD Studio. There is so little information about FMOD Designer that I have to find the answer here.  
I developed a c++ program on Linux to load fev files. But the error was reported when loading fev(when using eventsystem-\>load()). The fev file was built by Fmod Designer for PC(included linux platform).

```auto
ERRCHECK(result = FMOD::EventSystem_Create(&eventsystem));
ERRCHECK(result = eventsystem->getSystemObject(&fmodsystem));
ERRCHECK(result = fmodsystem->setOutput(FMOD_OUTPUTTYPE_NOSOUND));
ERRCHECK(result = eventsystem->init(64, FMOD_INIT_NORMAL, 0));
ERRCHECK(result = eventsystem->setMediaPath(path_new));
ERRCHECK(result = eventsystem->load(file_new, 0, &eventproject));
->FMOD error! FMOD_ERR_FORMAT. Unsupported file or audio format.

```

The log is when fev file be loaded:

```auto
MOD: EventSystemI::init : maxchannels = 64. flags = 00000000
FMOD: SystemI::init : FMOD Ex Version: 00042636

```

Could you any please tell me the reason why?

Thank you so much!
