Thanks.  Apparently the default pin config values are wrong, so it's a
BIOS bug.

I reread the pin-configuration spec and my last patch is correct.  The
configuration of 7.1 outputs is Front/CLFE/Rear/Side.  So, I committed
a patch to HG tree.

Now about your fix.  I think the best way is to override the pin
default configuration.  The patch below is the fix on the top of the
latest ALSA HG tree.  Use hg.alsa-project.org since
hg-mirror.alsa-project.org seems (again) out of sync right now.

I have a plan (even high position of my TODO list :) to move the
HD-audio configuration parser to user-space so that this kind of hack
/ fix would be more easily done.
