I have that program under multimedia / "pulse audio volume control" and 
I ran that prior to asking the forum for help.  The problem is that 
there are many options and I can't tell which is the right one.  As far 
as I can tell, everything looks to be correct.  Then again, it's hard to 
tell from this program.  On the Output devices tab it shows:

Port... HDMI / Display port it shows nothing on the drop down
         list for this item

PCM     is grey but also the check box for this item is enabled.

Front Left and Front Right are grey but the slider is at 100%

Built in Audio Analog stereo  .. there is a green check mark here.

Show:  All output devices is selected.  The other options are Hardware 
output devices and Virtual output devices.

Like I said, the output of pavucontrol is hard to make sense of.
