In FMOD Studio you can identify buses containing a resonance audio listener by running a query in the Mixer search bar. Typing `#query:(Plugin.identifier == "Resonance Audio Listener")` will filter all the buses containing a Resonance Audio Listener. For example, in this project the Resonance Audio Listener is on the SFX and VO buses:

Running the query returns all buses containing the a Resonance Audio Listener:

Copying the path for either of these buses will put `bus:/SFX` or `bus:/VO` in your clipboard respectively.

In Unity, to determine if a bus contains a plugin instance is less straightforward. You would need to perform a linear search from the master bus and down to any child buses for any instances of the “Resonance Audio Listener” dsp. Here is a [basic example](https://qa.fmod.com/t/how-to-access-and-manipulate-effects-in-an-event-at-runtime/18135/2) of how you do this on an event instance which should be a good starting point.
