Any body else got time to help, now that my excellent helper is gone.
Ok Mike, I'm back from Canada and I'm ready to start again. As I said, I went through the list of things to do from the forum. Here's my "lsmod | grep snd" as of now
caelinux at bill-desktop:~$ lsmod | grep snd

When I ran alsamixer everything was unmuted and the sound was turned up
Then I ran
caelinux at bill-desktop:~$ sudo aptitude search libasound2-plugins pulseaudio-* paman padevchooser paprefs

Bill,
lspci lists devices which are on the pci bus, and often manufacturers hook things into the pci bus directly from the motherboard (or at least that is my understanding). It does not necessarily have to be a pci card. Do:
$lspci
It usually lists way more devices then slots available on the computer
I also believe (but may be wrong) that sigmatel made the audio stack, but used intel chips. They actually build the compnents, logic and controllers around the intel chip so that it will work. Many companies do this type of thing. Hence they slap their name on it, but the main module really requires intel. A quick internet search seems to bring up intel and sigmatel alot partnering togeter in audio, so it doesn't sound that far fetched.
Although 82801G is not listed by name in the sound card matrix: http://bugtrack.alsa-project.org/main/index.php/Matrix:Main
Intel produces families of chips, that usually use the same driver. Yours is the ICH7 family. So I looked that up under Intel: http://bugtrack.alsa-project.org/main/index.php/Matrix:Module-hda-intel
And you need this driver:
snd-hda-intel
It looks like you already have this loaded according to your lsmd | grep snd

You may want to check and make sure that is still the output if you have messed with things.
Next I want you to run
$alsamixer
Key problems people have here are:
Sound channels are muted
Volume is not turned up in alsamixer
Please play with it and unmute everything in alsamixer while you have music/sound playing on your desktop. Unmute is done by the m key
Also make sure sound is up in alsamixer on EACH channel
It may be that a sound channel is muted, or volume was to low. Let me know.
If that does not work:
Another problem is that Pulseaudio started to replace the normal sound system around Hardy . I think it was the default in Hardy. It was new and didn't have all the bugs out yet.
I want you to check to see if you have it installed, as that chooses where we go from here. Run
sudo aptitude search libasound2-plugins pulseaudio-* paman padevchooser paprefs
pavucontrol pavumeter
And let me know if any are installed. After that we will go from there
Enjoy your trip
Mike
