Comment 252 for bug 116326

The good news :
The main issue remaining with Realtek ALC268 was that mics doesn't work.
Alsa 1.0.18a contains a fix for that:

This add a new model acer-dmic for all laptops that have digital mics.

The bad news :
Jaunty doesn't have alsa 1.0.18a :-(
It is currently stuck with alsa 1.0.18.
