Another installation problem for my new DP55KG motherboard with an
i5-750 4 core cpu. No Sound!.

The chipset is the P55 set and supports AC-97 and HDA protocols. I
used the latest Debian Squeeze Network Installation Disk. Neither the
onboard jacks or the front panel jacks work. I've checked the system
tray audio setting and the intel HDA mixer settings and the generic
settings. Everything seems to be OK. Anyone have a clue as to why the
sound doesn't work.

This is one of two problems with my Linux installation on this
motherboard. The onboard 82578DC Lan chipset doesn't work either. I
solved this one by adding an above board NIC.

Latest Squeeze, so kernel 2.6.32 and Alsa 1.0.23, I think.

What does the command
lspci -v
say about your sound card (and your onboard LAN for that matter)?

And do you see a full set of mixer controls if you run alsamixer?
