Hi;

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.

On Wikipedia, I recommend checking "See also", "References" and
"External Links" at the bottom of each page to find further and deeper
explanations.

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.

Thanks all.
