Set Buffer Size

How can I change buffersize in FMOD Studio Unity Integration 1.09.06 ? I try to set it by RuntimeManager.LowLevelSystem.setBufferSize but nothing change. it is on default values like before I mean 1024 and 4. I want to change it to 512 and 2.

Make sure you are caling setDSPBufferSize before System::Init in the RuntimeManager.cs.
It won’t work if it is called afterwards, have a read through the docs to make sure there isn’t anything you may have missed:
