Mmm, that looks like a new sound codec or at least I've never seen that
before.
Have you tried with the usual things (alsamixer/gnome applet volume
control) to configure the Intel card? Ensure you are using the Intel card
because you also have a secondary one, coming from nvidia HDMI ("cat /
proc/asound/cards" will tell what's the default).
I could only found an Ubuntu bug for a similar card/chipset:
***
[IDT ID 76e7] Dell Latitude E5520 - No sound through internal speakers,
sound is only from headphones output with Ubuntu 10.04.2 and 10.10 -
update Lucid ALSA LBM to latest release (1.0.24)
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/792233
***
The bug points to the latest ALSA version but I'm not sure if that will
solve your audio problem. To avoid messing up things, I would first try
to load a LiveCD with the latest ALSA version (1.0.24) and see if that
works. If yes, then consider upgrading ALSA for your Squeeze install.
