Build Type: Happens when running PIE in editor as well as in a Development build (not tested other build types)
Build version: 4.14.X (0 or 1, happens in both), never happened in 4.12.5 (not tested in 4.13)
Detailed description of the issue: Audio stops playing after loading a new map. There is no telling which map because it randomly happens with different maps, in different projects (see the details on the following threads, there are multiple people with different projects which get the same issue).
Here there are a few details about the issue, when it happens and how.
-
the sounds stop when the map is loaded (for example, we have a music file that starts right before the scene is shown to us - because we do some initialization that takes time before we render the first frame, music plays for a second and then pauses when the engine starts rendering - only happening when the sound uses its own thread, otherwise we cannot hear the music playing at all)
-
the sounds play correctly when we resume the game (all sounds that should have played, play after resume UGameplayStatics::SetGamePaused)
-
they can play a short sound or a longer sound (steamed or not), its the same error and happens regardless.
-
its not related to running in its own audio thread (tested only in PIE, not sure separate audio thread is supported in Editor), it happens in both cases
-
sometimes if the same sound is played for multiple times (with PlaySound2d or PlaySoundAtLocation, for example UI selection sounds or weapon sounds) it gets skipped once or twice based on how many times it has been played (I guess) which might have something to do with sound concurrency

Repro Steps
It doesn’t happen all the time, here it seems never with the first map we open. However, it will happen at the second/third map we open and always happens within 3-5 opened maps, we can say while playing the game it is 100% certain it will happen. Once it happens in a map it doesn’t mean the next map will have the problem too, sometimes it happens, sometimes it doesn’t.
