(Get the code!)
I have the same hardware on my laptop, with Ubuntu 10.10 installed.
Weeks before I could not make my mic working, but the speaker and headphone work well.
And I had no luck with the latest alsa in the PPA.
Once I thought this should be a bug in pulseaudio, because I found I can record through the command arecord
But the problem still existed after upgrading pulseaudio...After that even arecord could not work (maybe because of some packages upgraded during that period, probably kernel image)
Recently I built the 2.6.38 kernel for other reasons, I found my mic magically works! There seems still some problem with speaker/headphone auto switching, but at least this van be controlled in the 'sound preferrence' from the panel applet.
I would like to provide more info if needed.
