Because my desktop machine have similar issue with an Nvidia integrated
soundcard related, I looked again what volume meters are muted default
when I booted with Ubuntu 10.04.3 live CD my desktop machine.
The results is very similar with I experienced the Intel N10 soundcard
related.
I only doed following:
1. After the desktop presented my screen, I opened GNOME Terminal, and
ran amixer >sound1.txt command to store original mixer values with a
text file.
2. I launch Sound preference tool, and uncheck only the mute check box,
not increased volume meters.
3. I ran again with amixer >sound2.txt command to generate new changed
volume meters with an another text file.
4. I ran diff -u sound1.txt sound2.txt command to generate a diff style
output what volume meters status are changed from off to on after I
unchecked the mute checkbox in Sound preference tool.
I attaching the sound1.txt, sound2.txt, and
sound-volumes-differences.txt files.
To easyest your work, I copyed diff output:

After I done this three file generation, I reboot with live CD, and look
in terminal what volume meter status change resulting sound turning on
this sound card resulting I hear sound again.
When I ran amixer set 'LFE',0 on command, I hear sound again, because my
machine only have connected two speakers.
So you see, my desktop machine the Nvidia sound card related little
different volume meters are muted by default, but amixer set 'LFE',0 on
command result sound turning on too if two speakers are connected this
other sound card.
I try making a patch with merging this two bugreport fix with one patch.
When I done this fix, generating a custom live CD and testing two
machines the patch.
I attaching future this bugreport the patch, or the other bugreport Bug
564472)? What type fix you are accept future?
I attached the my desktop machines generated soundcard related text
files with following bugreport:
