However it didn't fix the issue at all, i still have the same problem, the card is recognized without problems but the problem persist even if i mute everything on my onboard card...Also in Mumble the problem is present and i choosed the right channels of the card, so is this problem still not related to ALSA?
What is the channel for the mic input of the USB card, to be sure?Here is my amixer output
Perhaps the issue is a pulseaudio one, not ALSA?
A few pulseaudio related fixes/hacks needed for GoogleTalkPlugin:

Hi,
A few posts have been about microphones. In particular the auto level
adjust feature that google chat uses. Others, who have had issues with
the internal mic on their laptops/notebooks read on too....
This auto adjust CAN be tuned off.
My symptoms are the same as lintex i.e. for the internal mic to work
the left mic channel must be turned down to zero and the right channel
set to the desired level. Google talk however automatically adjusts
both channels to what it thinks is optimum and thus screws this up.
To see the mix channel settings use PulseAudio Volume control and go
to the input devices tab. PulseAudio Volume control is in the Linux
menus under the sound and video submenu (on Ubuntu anyway). You may
need to install the package pavucontrol to get this gui.
To turn off the auto adjust:
cd ~/.config/google-googletalkplugin # get to google chat's directory
cp -p options options.bak # make a backup before changing stuff !
gedit options # edit the config file
now change one of the lines so that it reads as follows:
audio-flags=1
Now restart you machine and google chat will now longer auto-adjust!!!
Remember to go to PulseAudio volume control just to make sure the left
channel stays at 0

I had crackly audio issues -- not bad but annoying. I realized I'd
made some changes to my pulseaudio configuration a long time ago.
If you are comfortable with sudo and a text editor you might try experimenting:
Open /etc/pulse/daemon.conf.. Not sure which of these made the
difference. I was suing src-sinc-best-quality but I think even on my
quad core 3.8Ghz machine it was not doing me any favors. I also
adjusted the number of fragments and the fragment size. You won't find
the comments (lines with ;) in your file because I added them. But you
should find resample-method, default-fragments, and
default-fragment-ize-msec.
Here's the excerpt.
; choices in order from best to worst:
; src-sinc-best-quality, src-sinc-medium-quality, src-sinc-fastest,
speex-float-{10-0}, speex-fixed-{10-0}, ffmpeg, src-zero-order-hold,
src-linear, trivial
; default is speex-float-1
resample-method = src-sinc-fastest
And further down:
; default is 4 and 25
; was suggested to do 8 and 10
default-fragments = 32
default-fragment-size-msec = 25
Now my calls are GREAT quality!!!
