Ubuntu 16.04 - No sound from speakers. But headphone works fine.

[nepupya]

I use my computer with a dual boot. Win 10 and Ubuntu 16.04.2 LTS. After an upgrade in windows or Ubuntu i can't get sound from speakers. But headphone or an hdmi output works fine. It would really appreciate if someone finds a solution for my problem.
