It not works on editor(Event, Sandbox) and Unity.  
But original sources is fine when I checked Event.  
Just some events not working suddenly. (not mixer’s fault)

SFX\_Player\_Attack is working but SFX\_Player\_Roll is dead.  
I dunno why

Hi,

Thank you for the screenshot.

Could I please grab more info:

- What version of FMOD and FMOD Unity integration you are using?
- Is there any error or warning logs you can see from the Unity console?

Did re-creating the event or rebuilding your banks resolve the issue?

Could you please confirm if there are any noticeable differences between these two events? For example:

- Do they have different effects, like a spatializer or other effects, attached to their master tracks?
- Are they both using the same output bus?
- Do they share similar trigger conditions or parameters?

am using Fmod 2.02.20 and Unity 2022.3.15f1!  
and it is FMOD problem so no unity error logs.

- no master track effect
- same bus
- and no paramater or triggers

and when I back to previous version, it worked. really dunno why qwq…

Thank you for the clarification.

Just to confirm, are you saying the events only work in a previous version of FMOD?

Unfortunately, I’ve been unable to reproduce the issue on my end, so I may be doing something differently than you.

Would it be possible for you to upload your project or a minimal reproduction of the issue to your [FMOD Profile](https://fmod.com/profile#uploads)? This will allow me to test it more effectively on my side.
