i just got one: the Creative card. my ATI GraficsCard seems to have a HDMI connection and Ultimate Edition identified it as soundcard. and what this Intel Card is all about... well i dont know and no my motherboard does't have any onboard card. so im a bit confused^^ but everything seems to work now: Sound and Microfone.
2.7 fresh installation? well uff ive just installed 2.6 and i'm happy that it works as i want it to work (g15, sound+micro, programs, wine, amarok and so on :>).
well i think about it and thanks.
just if someone have the same problem as i have: you could copy the "/lib/modules/2.6.32-22-generic/kernel/sound/" folder from a liveDVD back to your system - it worked for me.
then you can see with "hwinfo --sound" what modprobe command you need to use - my was "sudo modprobe snd_ctxfi".
