I can't hear the audio when I'm playing levels in the editor.

I have Unreal Engine 4.8.2

I was searching how solve this problem in others posts but it isn’t work for me so, I decide to ask myself.

The problem is when I play a level on the unreal engine editor the audio don’t sound, I see in the miscellaneous and
in sound i have checked the last box (Énable Editor Sound), in world seeting I put on the maximum the audio level.
I don’t know what else I need to do.

P.S. I’m not English, sorry for my bad english (I’m Spanish).
