I ran this on my home system (Intel DP965LT - STAC9227).  Attached is
the graph to add to your samples.

I also am submitting the first (of possibly many) patches.  This one
will also look in the $PWD for the codecgraph.py file, so users who
don't wish to install this can just download and run it in place.

I noticed a few output errors as well:

        6: Unknown item: No Modem Function Group found
        10: Unknown item: Default PCM:

But as I am not yet familiar with python, I'd like to just report these
for now.

As to "my script", first let me clarify that it isn't mine.  A user
(wishie) on #alsa at irc.freenode.net worked with me to develop it, but
he deserves full credit.  On that note, these both should be added to
alsa-utils or alsa-tools and to the main web site.  Together, they will
make development/debug much nicer.
