On a fresh updated install, there is no sound from built-in speakers. Headphone jack works. This bug is possibly similar to #632046.
I have checked that the Fn-f4 has not muted the sound. alsamixer indicates that sound is not muted.
I previously had kubuntu installed and sound worked for some time.
Ubuntu release 16.04.1 LTS
alsa-base version 1.0.25+dfsg-0ubuntu5
