If you start a second FMOD system while the first is still running than there will be problems because the network port is already taken.

Due to the underlying networking implementation of some platforms, reporting of network errors is delayed until Studio::System::Update() is called. Studio::System::Init() will return successfully.

You can use the lowlevel System::SetAdvancedSettings() ([http://www.fmod.org/documentation/#content/generated/FMOD\_System\_SetAdvancedSettings.html](http://www.fmod.org/documentation/#content/generated/FMOD_System_SetAdvancedSettings.html)) to change the listen port and stop the two systems conflicting.
