The function you’re looking for is [`System::setDriver`](https://www.fmod.com/docs/2.02/api/core-api-system.html#system_setdriver), which allows you to set the output driver for your Core FMOD System. This function only takes an `int` representing the index of the driver to set as output though - if you need to enumerate your drivers to know which to use as output, you can use [`System::getNumDrivers`](https://www.fmod.com/docs/2.02/api/core-api-system.html#system_getnumdrivers) to get the total number of drivers, and then get info for each of them with [`System::getDriverInfo`](https://www.fmod.com/docs/2.02/api/core-api-system.html#system_getdriverinfo).
