I’m working on a game completely consisting of sounds in unity, and I want to make use of FMOD’s callback system to identify things like music end, and beat markers, the problem is that I am completely unable to do anything from inside the callback in unity. I’ve done a lot of things to try to work …

Callbacks require the use of explicitly pinning memory so that the memory isn’t freed by the garbage collector. We have an example on our website of how to use callbacks: https://fmod.com/resources/documentation-api?page=content/generated/engine_new_unity/script_example_timeline.html#/

I believe the fix for that will be the same as posted here:

It is due to the GCHandle being freed before the callback is actually finished with it.
