I also have this issue with my Inspiron 1420N (same card as mentioned above, also with the built-in Mic):
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
I did have it working fine under Hardy, although I remember it taking a lot of messing around initially.
So for me it's "here we go again" under Ibex where trying to get the Mic working properly is a baffling ordeal...
