Maybe you should try this:
1.Build a project,import the sound wave.
2.Use PlaySound2D to play it On BeginPlay Event.
3.Find a devices have Xposed installed.
4.Install the game to this device.
5.game will crash on this device after the sound play finished.
The most important thing is this issue only happend when device have installed Xposed.If device does not have Xposed installed,it will work fine.
