By default FMOD will use the system default output device.

The best way to change the output device that FMOD uses is:

- Find out how many devices there are ([`FMOD::System::getNumDrivers`](https://www.fmod.com/resources/documentation-api?version=2.0&page=core-api-system.html#system_getnumdrivers)).
- For each driver get name ([`FMOD::System::getDriverInfo`](https://www.fmod.com/resources/documentation-api?version=2.0&page=core-api-system.html#system_getdriverinfo)).
- Use the name to determine the index of the wanted device.
- Set the new driver ([`FMOD::System::setDriver`](https://www.fmod.com/resources/documentation-api?version=2.0&page=core-api-system.html#system_setdriver)).
