Normally I would have jumped in earlier to help, but I am swamped,
between my real job (non-alsa related), school (BS IT degree program),
and recent flooding activity in Oregon a couple of weeks ago.
What I can do, is ask you to download and run
Also, rebuild the modules with "./configure --with-cards=snd-hda-intel
--with-debug=detect" and load them with "model=auto". This will leave
output in dmesg as to what the driver finds in bios. It's not always
reliable, but it helps.
As to 5.1 surround, the only way to get 6 channel output would be
through the SPDIF port, as it acts as a digial passthrough. If your
system has a subwoofer, it is very likely tied into the main speaker
out, just like the 2.1 speakers you can get at most stores.

In theory, there is no difference between theory and practice. In practice,
