OK, here I am looking at my settings.

These look like good information.  Did you already check on all the
settings they describe?  I assume you did.

Neither of the pages you site above say anything about snd_seq_oss.  Did
you forget a reference somewhere?  I don't think it matters since I
don't have snd_seq_oss running either.

My direct comments follow my settings display...

Comments:

1. Note the modinfo output shows that you are using an smp kernel while
I am not.  Did you check your kernel configuration settings?  That first
 web pager reference states:

"Kernel 2.6.16 Note: Interestingly enough, the driver for the Intel HD
Audio in kernel 2.6.16 is broken. Everything appears to work fine, but
alas there is absolutely no sound no matter what you do. I was able to
get my sound card working by installing the latest ALSA driver, lib and
utility.

If you need to do this, you need to turn off ALSA support in the kernel.
You still need to enable sound support though:"

We are both running the 2.6.16 kernel but, since yours is smp maybe the
packager for your binary enabled the ALSA driver in the kernel, thus
breaking your sound as the quote above states.

2. The list of snd related drivers is a bit different but appears the
same for the drivers that I think "count" for this situation.  Does
anything jump out at you or anyone else?

At the moment I think the kernel setting of the ALSA driver is the first
thing to check.  I did not check the settings of my own kernel.  I'll
have to do that as soon as I remember how to derive the settings out of
the kernel binary.

How do you want to proceed from here?
