Thank you for testing that and sharing your code.
I have been able to reproduce the same times. I will pass this info on to our development team. However, I will note our docs which addresses latency on Android: FMOD Engine | Platforms Android - Audio Latency.
As OpenSl has been deprecated: https://developer.android.com/ndk/guides/audio/opensl, I cannot say that it will be safe on all devices. You could attempt to initialize the FMOD system with OpenSL and on failure resort to AAudio?
Unfortunately, you cannot filter outputs when using AUTODETECT, I could suggest this to our development team to look into however.
I will link to a post where some options for dealing with latency were discussed: High latency with AAudio - #2 by jeff_fmod.
