We are using FMOD in Unity’s mobile game project, we want to detect when the user has been inactive for a long time, temporarily stop FMOD, and wake up FMOD when the user restarts the operation. Is there a way to achieve this?

I see that `CoreSystem` has `close()` and `init()` apis, can I use them for this purpose?

The API call you’re looking for are likely [System::mixerSuspend](https://www.fmod.com/docs/2.02/api/core-api-system.html#system_mixersuspend) and [System::mixerResume](https://www.fmod.com/docs/2.02/api/core-api-system.html#system_mixerresume). It’s worth noting that you should avoid making FMOD API callbs between suspending and resuming, as you may run the risk of causing a deadlock.

Is it possible to reduce the hardware performance overhead of FMOD when pausing in this way?

I ignored the description in the documentation, which can really reduce the overhead of hardware performance:

> Used on mobile platforms when entering a backgrounded state to reduce CPU to 0%.
