We are experiencing a very loud random glitch when a specific 3D event plays in Unity. This seems to occur rarely (around 1 out of 50 times). When this bug occurs, this event (a short creature grunt sound) will trigger a 3/4 seconds noise with a RMS level of around 0dBFS (very loud).
The event has the following specifications:
- It’s being called directly by the PlayOneShot() method (it is NOT assigned to an FmodStudioEventEmitter)
- 3D Panner with the default options, except for “Max instances” (they are set to 2) and Min&Max Distance (set to 10.0-40.0)
- a first audio track that plays a multi-sound module.
- 1 parameter that will trigger different multi-sound modules on a second audio track, depending on its value.
We are using Fmod Studio v.1.06.02 and Unity v5.3.3f1
Any ideas why this is happening?
