Stan, I have taken your advice and I am pursuing it diligently.  My fist
quick questionis;

/docs/HD-Audio.pdf says:

"The HD-audio component consists of two parts: 
1) the controller chip, and, 
2) the codec chips on the HD-audio bus. "

Checking with lshw:
On my machine they are:
1) [82801G (ICH7 Family) High Definition Audio Controller]
2) And nothing obvious to me for the codec chip.  Would this be the
hardware I am looking for:
        *-pci:2
             description: PCI bridge
             product: 82801G (ICH7 Family) PCI Express Port 2
             vendor: Intel Corporation
             physical id: 1c.1
             bus info: pci at 0000:00:1c.1
             version: 01
             width: 32 bits
             clock: 33MHz
             capabilities: pci normal_decode bus_master cap_list
             configuration: driver=pcieport-driver
             resources: irq:26 ioport:d000(size=4096)
memory:e4000000-e4ffffff ioport:e5200000(size=1048576)

and, would the pcieport-driver be a digital-to-analog /
analog-to-digital driver.  /docs/HD-Audio.pdf says there should be a
specific driver.

If not, what should I be looking for?  
Is the codec chip just considered part of the 82801G (ICH7 Family) and
snd-hda-intel the sole driver?

Actually most of that document is not too hard to follow, but this codec
chip question doesn't seem to be answered, and, googling doesn't give me
anything useful about my particular machine/motherboard that I can see.
