No audio in 12.10

[Cavsfan]

You have a different issue (unless you have exactly the same hardware), as audio hardware tends to be very specific, and a model hack was needed there

Not sure why you would say that. When you login and have no sound and then look at the Sound Settings in gnome and "Dummy Output" is selected.
Then entering sudo alsa force-reload in terminal fixes the problem, it doesn't matter what type hardware you have.

Folks here https://bugs.launchpad.net/ubuntu/+s...r/+bug/1106334

solved this problem for me! the solution was to:

edit /etc/modprobe.d/alsa-base.conf
and add the following line
options snd-hda-intel model=3stack

Guess there are 2 ways to fix it. Myself, I find entering sudo alsa force-reload the easiest.

Hi everyone. I had the same issue with the same HDA Intel (Realtek ALC880) card and doing BOTH things you suggest fixed it.
I'm using Ubuntu 13.04, so this work with this version too.

First step:

Open the terminal and paste this:

sudo gedit /etc/modprobe.d/alsa-base.conf

Add the following line at the bottom of that file:

options snd-hda-intel model=3stack

Second step:

Paste this on the terminal:

sudo alsa force-reload

Thanks everyone! =D>
