I'm working on hiding exactly that at the UI level (gnome/pulseaudio 
level rather than ALSA), but that is a long-term goal and not all pieces 
are into place yet.

A very similar machine, Asus 1215P [1], was enabled by the team I'm 
involved with, so yes, it definitely works for someone, and it would 
surprise me if it does not work out of the box from an Ubuntu 11.10 Beta 
Live-CD even though the link says "pre-install only".

You could try this terminal command:

speaker-test -D plughw:SB -c 2 -t sine

And see if that outputs sound (try both headphones and internal speakers).
