Hello,

I’m developing a game in Unity using FMOD, and after updating both the FMOD plugin and FMOD Studio to version **2.03.06** , I’ve encountered an unexpected issue with parameter initialization.

It seems that event parameters are **not being properly set to their default values** (as defined in FMOD Studio) when the game starts. From what I can tell, they might be initializing with a different value on the first frame and then correcting themselves on the second frame. However, for parameters with **seek speed enabled** , this delay means it can take some time before they reach their intended default values.

As a workaround, I’ve manually set all event instances to their default parameter values upon creation. This issue was **not present in version 2.02** , and I haven’t made any other changes to the project apart from updating FMOD.

I wanted to report this behavior in case it’s a bug or an unintended change. I’ve tested this in a new empty project and the problem persists. Has anyone else experienced this, or is there an official fix?

Thanks!

Thanks for the bug report. I unfortunately haven’t been able to reproduce the behavior you’re describing, so to confirm:

- Are you able to reproduce this issue in the [Sandbox](https://www.fmod.com/docs/2.03/studio/the-sandbox.html) in Studio? Or does it only occur in Unity?
- Are you playing the event with your own script, or with a Studio Event Emitter component? If it’s the former, could I get a snippet of the event creation code in which the issue occurs?
- Could I get you to provide a short series of steps that reproduces the issue for you in a fresh Unity project?
