Ok, I updated Ubuntu, and now the onboard device is working again.
With the usb device unplugged:
sudo dmesg -c
[ 496.692447] usb 2-1.2: USB disconnect, device number 3
With the usb plugged again:
sudo dmesg -c

Again, in sound controller there is only the onboard device listed.

something in the USB descriptors the driver doesn't like.
It's "/proc/asound/cards", with a leading "/".

There's no need to install any extra driver. But yes, maybe your

attempts to do it anyway made the situation worse.
An update of Ubuntu should give you 3.5.0-26, which also ships with all
stock modules. You can try that. Alternatively, you can try installing a
much newer kernel. You can try if the x86_64 version of these archives
work for you:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/
Once you have your on-board ALSA device back, please try the following.
Disconnect your device, and enter
$ sudo dmesg -c
... then plug it back in, wait for ~5 seconds and enter
$ sudo dmesg -c
again. Then send the output to this list, and also check
/proc/asound/cards again.
