Output two different audio files to two different sources in one GameObject

It is not possible to assign two different output devices to the one FMOD System, you would have to run two separate systems and choose which system to use depending on where you want the audio to go. https://qa.fmod.com/t/output-two-different-audio-to-two-audio-devices-from-same-unity3d-game/12986/2
