alsa microphone problem

Hey!
I've got quite a problem with my microphone, actually. It works, I tried it on windows.
I followed the wiki stuff on ALSA, my card was automatically recognised. Sound works perfectly, with alsamixer. The problem comes from my sound input. I have an application that gives me the trafic on the input, and I activated the input with alsamixer -V capture. The channel is the good one, since I view changes when i plug the microphone in (during approximately 0.05s, there is a lot of traffic). But, when i talk into the microphone, nothing changes

tuxer@tuxer-laptop:~/Desktop$ ls -l /dev/snd/

Here are the two commands asked on the wiki.
Thanks for your help

Re: alsa microphone problem

I know it's no help, but I've also been unable to use the microphone with 2.6.30 (worked fine with 2.6.28). Using snd_hda_intel, too.

Haven't look into the matter as is something that I use seldom, but I've noticed that at boot time, just before the screen clears for login prompt, there is some message about HDA Intel and unrecognized hardware which perhaps is related. Sorry for not pasting it but I've been unable to find it greping in /var/log, it seems it's only dumped to the console.
