Yet another no mic thread.

Done... what should I do next? Still have no sound....

First, for mic problem, check this.
Gnome-alsamixer
Using Alt+F2 run dialog

 gnome-alsamixer

Use 'Edit -> Sound Card Properties' menu to enable elements.
Soundcard tab to select / adjust levels.
To install:

sudo apt-get install gnome-alsamixer

Then go to 'Sound Preferences' to select and unmute your mic in 'Input' tab.
Make sure you have selected a profile with 'duplex' or 'analog input' for the correct sound device on the 'Hardware' tab.
Use Pulse Audio Volume Control (pavucontrol) to unlock stereo sliders for the mic in 'Input Devices' tab. Drag the right slider down to zero. The mic is a mono device.

From alsa documentation:

Capture Problems
~~~~~~~~~~~~~~~~
The capture problems are often because of missing setups of mixers.
Thus, before submitting a bug report, make sure that you set up the
mixer correctly. For example, both "Capture Volume" and "Capture
Switch" have to be set properly in addition to the right "Capture
Source" or "Input Source" selection. Some devices have "Mic Boost"
volume or switch.

When the PCM device is opened via "default" PCM (without pulse-audio
plugin), you'll likely have "Digital Capture Volume" control as well.
This is provided for the extra gain/attenuation of the signal in
software, especially for the inputs without the hardware volume
control such as digital microphones. Unless really needed, this
should be set to exactly 50%, corresponding to 0dB -- neither extra
gain nor attenuation. When you use "hw" PCM, i.e., a raw access PCM,
this control will have no influence, though.

Thank you for taking the time to answer my posts. I really appeciate.

Still does not work... I have tried those suggestion before if I can remember well.

I'm starting to consider the fact that my mic might be physically damaged :S....

Could really use your alsa-info output. Can you post the link?

[cespinal]

here it is!!

Your driver update did not take:

!!ALSA Version
!!------------

Driver version:     1.0.21
Library version:    
Utilities version:  1.0.22

If you installed the linuxant driver, remove it. Also remove the alsa-base.conf entry. Now install build-essential:

sudo aptitude install build-essential

Next use the alsa-upgrade link in my sig to get full 1.0.23 version. From what I can see your laptop should work with that.

I thank you for taking the time to help me with this. Still nothing. Sound recorder for example will show some tiny feedback... but no sound at all at playback.
Here is again the latest alsa info: http://www.alsa-project.org/db/?f=3a...939c783398b426

Running the ubuntu sound bug script tells me there is problem in alsa-base

Thanks again for everything.

Quick comment... Reading my dmesg output found this:
[ 19.040159] input: HDA NVidia Mic as /devices/pci0000:00/0000:00:07.0/sound/card0/input9
[ 19.040275] input: HDA NVidia Mic as /devices/pci0000:00/0000:00:07.0/sound/card0/input10

Could this be the problem? two mics?

Probably not, as most have an internal and external mic input.

I have done all that before with no success. In the attached screenshot, you can actually see that all channels have been enabled in alsamixer, pavu control is set up as suggested and the sound preferences are set up as well.

As you can see in the sound recorder window. The feedback bar stays in that level no matter what I do.
