OK, good.

Strange.  This Intel chip appears to be a full-function audio chip.
But with no way to get data into or out of it, it's useless.

No, don't remove the heat sink.
So they integrated a sound chip into the chipset but then didn't provide
any way to access it.  Very strange.  What a waste.

Again, you've got to walk before you can run.  I know you want to get
sound working on the desktop.  That's your ultimate goal.  But first
we have to get sound working at all.  Let's concentrate on that.

That's because you blacklisted the driver for it.  That's good.

Walk first, then run.  Never mind the desktop for right now.

Did you install the firmware package that I suggested in another post?

Make sure that alsa-firmware-loaders is installed.  This is in "contrib";
so make sure that non-free and contrib are listed in your
/etc/apt/sources.list file.  See http://www.wowway.com/~zlinuxman/Kernel.htm
for a sample /etc/apt/sources.list file.  It's at the end of "Step 1".
Then run

   aptitude update
   aptitude install alsa-firmware-loaders

Then shutdown and reboot.  Then run

   dpkg-reconfigure alsa-base
   dpkg-reconfigure alsa-utils

Then shutdown and reboot again.

Then run alsamixer and check out the column names to see if PCM has shown up.
(All these commands except alsamixer must be run as root.)
