I have dual boot Lenovo Y50 with windows and Ubuntu 17.04. At first I had no subwoofer sound on Ubuntu, seemed like drivers were not properly installed. I checked: Realtek High Definition Audio Codecs answer to install drivers from Realtek. But now I have no sound at all. In my sound settings there is "Dummy output" only which produces no output.

Help please!
