Sounds like you’re trying to use FMOD Ex commands with the FMOD Studio API.

Please check the documentation at [http://www.fmod.org/documentation/#content/generated/lowlevel\_api.html](http://www.fmod.org/documentation/#content/generated/lowlevel_api.html) if you are not sure about what parameters are passed to playSound.
