Sound problem no speakers

[Patton Echols]

I have had difficulties getting sound to work correctly on my Netbook.  
The symptom is that the built in speakers don't work.  When booting, the 
"drum" sound plays, and that's the end of it.  The headphones do work.

After much googling, a couple of suggestions were found
(1) Install linux-backports-modules-alsa-lucid-generic
Done, did not fix the problem
(2) Edit /etc/modprobe.d/alsa-base.conf
add to file:
options snd-hda-intel model=laptop-amic
One site suggested "model=auto" instead.  I've tried that too.
(3) I'm really close with a suggestion to run "alsamixer" from the 
command line.  When I do so, I find the "Speaker" slider is set to 
zero.  I posted a picture of what I'm talking about at:

If I set volume to 100 (or any non zero value) then sound works 
correctly.  Speakers on and mute when headphones plugged and unplugged.

Here is the remaining problem.  This "fix" does not survive a reboot.

I have looked at the Pulseaudio chooser and volume control.  I see no 
obvious settings that would account for the behavior.  But then I can't 
make heads or tails out of most of it anyway.

Any thoughts?
