Sound / Voices / Music » Sound problems

Hi,

I've just updated to Lollipop 5.0 and now there is no sound coming out of the speakers. I have also tried it with headphones and it still does not work. If anyone else has/had this problem, do you know how to fix it?
Does anyone know if it is a bug with the update?

Please help.

I didn't find the right solution from the Internet.
