Hi I want to use two audio output devices, but don't know how

I am currently making a game with two audio device.

one device is for making vibration haptics with in-game made audio files.
The second device is for the game play sound.

The problem that I am facing now is, if I don’t seperate this two audio, then the device for making vibration will make a vibration with game play sound also. Such as player getting hit by enemy.
I haven’t disabled the unity audio system, my idea was to play vibration audio file in unity audio system(which will be set to default audio device), and play game play audio on my headphone.

I am very new to Fmod, and I want to know if there is any specific way to implement it.

Hi,

How are you currently triggering the vibration? What platforms are you planning on releasing your project for?

What version of the FMOD integration are you using?
