Thanks for the suggestion.  Seemed like such a good idea.  Apparently 
something is overriding the saved info because the changes still do not 
survive reboot.  I also discovered in the process "amixer" a CLI utility 
that will allow you to make and show sound settings.

Output with sound working
===========================
$ amixer sget Speaker
Simple mixer control 'Speaker',0
   Capabilities: pvolume pswitch penum
   Playback channels: Front Left - Front Right
   Limits: Playback 0 - 64
   Mono:
   Front Left: Playback 63 [98%] [0.00dB] [on]
   Front Right: Playback 63 [98%] [0.00dB] [on]
========Store Settings ==========
$ sudo alsactl store

=======After Reboot==========
$ amixer sget Speaker
Simple mixer control 'Speaker',0
   Capabilities: pvolume pswitch penum
   Playback channels: Front Left - Front Right
   Limits: Playback 0 - 64
   Mono:
   Front Left: Playback 0 [0%] [-63.00dB] [on]
   Front Right: Playback 0 [0%] [-63.00dB] [on]

Anyone other ideas?  I am most interested in suggestions as to what 
could be doing the resetting.  My guess is that something is 
mis-configured But I've no idea what.
