With special thanks to Tim and David, I have read and assembled a list
of audio explanation sites. Tim and David gave me enough context so
that when I read (or re-read) the information at these sites, things
began to make sense. I have copied the list of sites I have used for
anyone else who might be as befuddled as I was. I have tried to put
them into some logical order.

Sound (& Music) Creation and Perception
Computer Sound - Acquiring, transferring, storing, altering and
Musical Instrument Digital Interface
On Wikipedia, I recommend checking "See also", "References" and
"External Links" at the bottom of each page to find further and deeper
The main breakthrough for me was being shown that ALSA was a driver for
the sound card (chip) hardware, while PulseAudio was a server program,
in much the same way that 'ati' or 'nv' are video card drivers and X
windows is a window graphics server.
All other sound programs, codecs etc. are, at heart, just libraries used
by either ALSA or PulseAudio.
It is best to take a look at http://en.wikipedia.org/wiki/PulseAudio
flowchart a few screens down as recommended by David Timms just to get a
visual road map before starting in reading.
You will notice that the first 11 URL's I cite are for people like me
who have 'tin ears' and only have a secondary interest in sound as it
relates to music. As a side note, all my life I had distinguished music
as having only three characteristics; loud or soft, high or low; and,
pleasant or annoying. It seems that I wasn't as far off the mark as I
thought I was. I will, from hereon, try to pick up on and understand
some of the more basic musical nuances I hear.
