Ubuntu Multimedia :: Microphone Works But Does Not Record?

I'm running Ubuntu 9.10 on an Asus F3JC laptop with an integrated webcam and microphone. The webcam is a

Code:
user@ubuntu:~$ lsusb
Bus 001 Device 004: ID 05e1:0501 Syntek Semiconductor Co., Ltd DC-1125 WebCam

and it works. If i tap on the microphone or if I blow on it, I hear noises but after I record something with gnome-sound-recorder I don't hear any sound! The same with Skype, for example.

On Xp (other hd partition) it works.

The audio device on the laptop is a

Code:
user@ubuntu:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC660 Analog [ALC660 Analog]
Subdevices: 1/1

[Code]....

If I open the "sound preferences tool" the device for sound input is "Internal Audio Analog Stereo" and even if I tune the volume of the microphone I don't see any movement in the input level bar. I've also checked alsamixer and the digital volum in the capture interface is set at the maximum.
