I've done a fresh upgrade to 18.04 and had a "no sound" problem that I haven't found a solution to. I found this and have been using it to get the sound connected. Can't find the source again, unfortunately. Thought it might help to point to the problem. Reinstalling Alsa and Pulse; starting and stopping both; eliminating one or the other; did not work. The following identifies something and places "Built-in Audio Analog Stereo" into the sound output tab in Settings.
