[BUG] Loss of in-game audio in specific maps in air battles.

[Gentlespie]

Hello! I've found a weird issue with specific "AI" sounds where if some are enabled (even if it is gradually, one by one) on some maps like Afghanistan, Spain, Vietnam and Rocky Canyon sounds get removed oddly while playing top-tier jets. It has been narrowed down from engine06_ai to engine17_ai. Unsure what could be fully causing this as it somehow only occurs on the maps stated above, is it possible those maps have weird hidden events that break sounds more or it's completely unrelated?

@Uchuujin01 Sorry for ping, but this is important
This issue chased us for several months now, it is indeed somehow related with _ai engine events.

It's not one specific event that breaking the whole stuff, it's group of them - everything works flawlessly if engine06_ai to 17_ai excluded from the project.
But once all in, everything breaks leaving only UI sounds. Excluding one by one event seems to help, but during the battle some sounds are missing, and behavior is gradually worsening once you include more engines from the list until game completely mutes.

All events are checked twice, everything completely clean from various oversights, like too many layers playing at same time, accidentally turning on persistent mode, etc.

On vanilla side this bugreport sounds too familiar https://community.gaijin.net/issues/p/warthunder/i/wjrbckgWDJ1k
But I never caught anything on ground.
And yes it happens on said maps: Rocky Canyon, Vietnam, Afghanistan, Spain - basically most of them toptier maps and it is easily reproducible in replays and for some reason only these maps affected.

There's could be several points: The game spawns these ai engines out of nowhere only on specific maps, or FMOD version being buggy, because 2.02.14 version works far slower and has allegedly memory leak
