anyone got internal mic on STAC9228 working?

I'm on a fujitsu lifebook Q2010 laptop with the following audio device

lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

It has the STAC9228 chipset

head /proc/asound/card0/codec#0 
Codec: SigmaTel STAC9228
Address: 0
Vendor Id: 0x83847616
Subsystem Id: 0x10cf0100
Revision Id: 0x100201
No Modem Function Group found
Default PCM:
    rates [0x7e0]: 44100 48000 88200 96000 176400 192000
    bits [0xe]: 16 20 24
    formats [0x1]: PCM

i've never managed to get the internal microphone (on the side of the screens) work in linux - works in windows.
I'm wondering if anyone has had any luck with ALSA and this sound card??
I have alsa v1.0.18

thanks,
Shane

Check here http://bbs.archlinux.org/viewtopic.php?id=60197 , not exactly the same problem but related .... this high definition codecs ...... more of a curse than a bless. I have my own quarrel with the one in my laptop too. Best of luck trying to sort this out.
Also I don't know if you have used the builtin mic a lot (in windows) but my experience tells me that builtin mics are worthless (they pickup your voice and all the noise around, including your typing mouse clicks and maybe even the fan working), get a headset and the people on the other side of the chat will thank you smile. Maybe you can consider getting a usb headset, no more hassle of trying to get the HD Audio driver / codec to cooperate in making things work (do a little research first to see if it works well in linux though).

Give what you have. To someone, it may be better than you dare to think.
