You will need multiple FMOD System instances for this.

You’ll need to modify RuntimeManager.cs to startup and manage two systems each connected to different drivers (see the docs for setDriver function). Because FMOD systems are isolated from each other you’ll have to load data twice, and keep the synchronised manually if you want the same event playing in both.
