Hello,

I’m encountering an error where Unity is reporting I have more than 1 listener in my scene. Here is the error which is reported:

> [@](#):

> Too many listeners  
> UnityEngine.Debug:LogError(Object)  
> FMOD.Studio.UnityUtil:LogError(String) (at Assets/Plugins/FMOD/FMOD\_StudioSystem.cs:58)

> HutongGames.PlayMaker.Fsm:UpdateStateChanges()  
> HutongGames.PlayMaker.Fsm:Start()  
> PlayMakerFSM:Start()

As far as I can tell I only have 1 FMOD\_Listener script attached to my camera. I occasionally transition the camera between game objects, re-parenting it from one player object to another. This seems to work fine in some situations, but in one particular situation it regularly causes a crash.

I’m sorry I can’t give more information. I just wondered if there were any known issues with re-parenting FMOD\_Listeners. Or whether I was missing a necessary step.

Hi HiFiHair,

I haven’t seen that before, please send a project which reproduces the issue to [support@fmod.org](mailto:support@fmod.org) and I will take a look.
