Hi.

I have an User Widget which plays animation and play sound. The beginning of it looks like it:

Then in the Level Blueprint I’m launching the animation (that last long enaugh to play the sound) and then go to the next level:

The problem is that in the next level when I use memreport -full I can clearely see that the sound is still in memory!

Obj List: class=SoundWave -alphasort
Objects:
Object  NumKBytes  MaxKBytes  ResKBytes ExclusiveResKBytes
SoundWave /Engine/EditorSounds/Notifications/CompileFailed.CompileFailed 0K 0K 10K 10K
SoundWave /Engine/EditorSounds/Notifications/CompileSuccess.CompileSuccess 0K 0K 13K 13K
SoundWave /Game/GUI/Sounds/Splash-UnrealEngine.Splash-UnrealEngine 0K 0K 811K 811K
Class  Count  NumKBytes  MaxKBytes  ResKBytes ExclusiveResKBytes
SoundWave      3          3K          3K       834K       834K

Shouldn’t it be cleared somehow? Should it be done by Garbage Collector or manually?

That user widget that refrenceing to that USoundWave, you sure you don’t have it initiated in next level? GC won’t clean asset from memory if it’s referenced in other active object

I checked in the reference viewer and it looks like the widget is referenced only in the first map:
