how to look up which codec used by ich8 (audio)

Question

I'm having some difficulties getting the sound to work on an optiplex745.
I know that the system is an ich8 as given by the chipset q965.

But I can't figure out which codec is used.
This is the output of lspci -vnn
---------------------------------------------------------------------------
00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 02)
Subsystem: Dell Unknown device [1028:01da]
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at dfdfc000 (64-bit, non-prefetchable)
Capabilities:
---------------------------------------------------------------------------
I'm using alsa, and i guess forcing the right codec from the list in
/usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz

Will make the sound work.

Thanks in advance

This might be all you need at the end of your at the end of your /etc/modprobe.d/alsa-base file:

options snd-hda-intel model=auto

Try this at the command line first to see if it's going to work:

sudo modprobe snd-hda-intel model=auto

It worked for me.
