Under configuration, it lists two devices (this probably is the problem).

Number one:  GF116 High Definition Audio Controller
              Profile: Digital Stereo (HDMI) output.

Number two:  Built in Audio
              Profile: Analog Stereo Duplex

I think I am beginning to get a sense of what is going on.  Earlier this 
month I upgraded my video card.  At the time, I was not interested in 
the HDMI port that is on the card.  Now, when I use Xubuntu 12.04, there 
might be a conflict between the sound system that is on the motherboard 
and the new HDMI interface that is on the video card.  (My old video 
card did not have a HDMI port).  I'm not sure if this is the problem 
because when I turned the HDMI port off in the configuration tab, 
nothing happened.  Comments anybody?
