Sound in Totem disappeared

Goodmorning guys, I’m running suse 13.2 with Gnome. Since yesterday, without doing any update, sound in the application “videos” (Totem) is disappeared, in all the others application It works well.

Edit: maybe I’ve done a “zypper UP” the day before, so It may be that update that messed up, and the problem appeared when I’ve rebooted the following day.

Solved after the last update.
Thanks and sorry for multi-replying
