All works pretty good, I remember I didn't nothing unusual,just I installed a especific flash plugin to nuvola player, I can ear the sound with my headphones, but I can't I hear sound from the speakers.

When I put in the terminal pulseaudio appears crash when trying to start the daemon

I leave screenshot

and in the System configuration in output play sound through is empty, in the past there appears 4 options

I need reinstall pulseaudio???

Thanks in advance for the help
