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.

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.
