[LVL ED] Level editor won't set a sound entity to a sound element

[felixmole]

Sorry, I may not have been clear enough: I meant that yes, your solution does work (obviously). I can put the sounds' names with a text editor. But all these properties are cleared as soon as I reopen the map with the level editor. I suppose I'll have to take care of the sounds when I'm completely done with the map... Thank you for your input.
