[Bug 353206] Re: 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)

Thnk you for your time in advance:
what I did, I followed the link in http://ubuntuforums.org/showthread.php?p=6589810#post6589810 
step 1,
I tried to toggle the 'input source' in alsamixer:
see my .png
I have two options:
Front mic and Line,
tried to select Line and check it using sound recorder; result: beep
toggled again to 'Front mic' and check it using sound recorder; result: beep

step 2,
uninstall alsa-backports; I do not know if I have them, either how to chek it, but I tried the following in terminal:
sudo apt-get purge linux-backports-modules-alsa-lucid-generic:
Sudo says is not installed so it cannot be removed, so trying again with the upgrading.

Closing all programs that can need the alsa (ekiga, sound recorder,
pidgin, leaving only openoffice, firefox (without music for your post)
omegaT) and running the script

step 3,
download the script and save it somewhere
2. cd <your-download-dir>
3. tar xvf AlsaUpgrade-1.0.23-2.tar
4. sudo ./AlsaUpgrade-1.0.23-2.sh -d
5. sudo ./AlsaUpgrade-1.0.23-2.sh -c
6. sudo ./AlsaUpgrade-1.0.23-2.sh -i
7. sudo shutdown -r 0

step 4 checking the version
cat /proc/asound/version:
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Jun 10 2010 for kernel 2.6.32-22-generic (SMP).

step5 testing aplay
speaker-test -Dplughw:0,0 -c2: test OK

step 6, multiples checking:
check if your alsamixer-channels are activated and unmuted (gnome-mixer/volume-control/preferences)!! :
see in my .png that nothing is unmuted

step 7, /etc/modprobe.d/alsa-base.conf:

# autoloader aliases

options snd-pcsp index=-2

step 8, as it seems that the line options snd-hda is missing I will
added manually

step 9, searching model hda using the following command:
cat /proc/asound/card0/codec#* | grep Codec:
Codec: VIA VT1708S

cat /proc/asound/card0/pcm0c/info:
card: 0
device: 0
subdevice: 0
stream: CAPTURE
id: VT1708S Analog
name: VT1708S Analog
subname: subdevice #0
class: 0
subclass: 0
subdevices_count: 2
subdevices_avail: 2

step 10, waiting for help:
As this model "VIA VT1708S" is not present in HD-Audio-Models.txt do not know what to add and I am stopped,

Found in here http://ubuntuforums.org/showthread.php?t=1496329&highlight=screensaver+working 
the output necessary to check issues. here it is:
