UE:4.27 plus (latest on perforce)
We are having multiples issues with leaking audio events. At first we had this (all this are events) shown on the profiler
this caused that some new events won’t sound or sound glitched (probably caused by memory limits)
Debugging a little we found out that when the glitches started the fmod playback state never changed from “FMOD_STUDIO_PLAYBACK_PLAYING”, probably because it gets created, FMOD can no longer handle it (because of memory) and it gets lost, but still occupies memory.
We also tried pre-loading all events (using “Load All SampleData” from the project settings on UE) which, ironically, seems to have fixed most of the issues(at the cost of overall memory cost, about 1gb more usage just for FMOD)
Preloading manually some events brought back the issue. (using UFMODBlueprintStatics::LoadEventSampleData(GetWorld(), fmodEvent))
Insights appreciated. We are starting to investigate if the same issue happens with 2.02.15
