Really. This is ridiculous. The setup program is supposed to take care of these details.

hwinfo says my audio is "Intel 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller" That's not even listed in that text file. So, what do I do?

In all previous releases, the sound simply worked. Users shouldn't have to hack their system to get basic functions.

I did a clean install because upgrade wouldn't work.

Upgrade postponed. No way is 12.04 ready for release!

Well, I really didn't expect we need to handle so much audio stack details to fix our sound and I'm totally layman. Well from what I learned and practiced, I think if in the similar situation of mine, we just need to find a matched vendor model option for our audio codec chip.

You can get your ACC type from

aplay -l

and go to the corresponding section of
http://www.kernel.org/doc/Documentat...dio-Models.txt

and try each model option and restart. Hope you have that luck.

Just FYR

"What `model` option values are available depends on the codec chip. Check your codec chip from the codec proc file (see "Codec Proc-File" section below). It will show the vendor/product name of your codec chip. Then, see Documentation/sound/alsa/HD-Audio-Models.txt file, the section of HD-audio driver. You can find a list of codecs and `model` options belonging to each codec. For example, for Realtek ALC262 codec chip, pass `model=ultra` for devices that are compatible with Samsung Q1 Ultra. Thus, the first thing you can do for any brand-new, unsupported and non-working HD-audio hardware is to check HD-audio codec and several different `model` option values. If you have any luck, some of them might suit with your device well."from http://www.kernel.org/doc/Documentat...a/HD-Audio.txt

Thanks! This fixed it for me. Problem occurred after I installed and played around with gnome-shell, gnome-panel, xubuntu-desktop and xfce4, and then uninstalled them all after deciding Unity suited me best.
