Mic is not recognized using card [HDA NVidia] VT1708S Analog in ubuntu 10.04 either in 8.04 (gnome) no help upgrading ALSA.
Hello,
I have already read most of the posts in internet related to: ubuntu sound problem, trubleshootings, ekiga sound problem, mic sound problem, capture audio problem, pulseaudio (already killed and removed), ALSA, gnome-volume-control (evrything is red, nothing is unmuted), alsamixer: see my .png
This are the output of the commands that are normally required for people being able to help you:

Your search - VIA VT1708S - did not match any documents.

I just cannot use my mic either in ekiga, either in sound recorder, either in audacity.
My mic is a SPEEDLINK headphones with mic that I plugged in with a jack.
these programs will behave different; ekiga and audicity will not register anything; sound recorder will register a high pitch beep.
uname -r:
2.6.32-22-generic

can you tell me what information I can post to try it further.
thank you in advance

I would suggest upgrading alsa again. This time follow the upgrade link in my sig and if you have alsa-backports installed, uninstall it and reboot first. Have you tried toggling the 'input source' in alsamixer?

[ignacio69]

Dear Lidex,
Thnk you for your time in advance:
what I did, I followed the link in your sig, that is: http://ubuntuforums.org/showthread.p...10#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:

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

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,
please, can you help me further to find out which model should add to my /etc/modprobe.d/alsa-base.conf.
Thanks in advance,

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 use pulseaudio volume control (pavucontrol) to select your mic in 'Input Devices' tab.

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.

Dear Lidex:
thank you again for your help.
It seems I have already installed gnome-alsamixer.
I tried the following
in terminal typed gnome-alsamixer: see gnomealsamutefrontmic.png
the front mic is muted, and the input source is blank
so I tried to check the input source with this result:
** (gnome-alsamixer:4028): WARNING **: gam_toggle_get_state (). No idea what to do for mixer element "Independent HP"!

** (gnome-alsamixer:4028): WARNING **: gam_toggle_get_state (). No idea what to do for mixer element "Input Source"!

** (gnome-alsamixer:4028): WARNING **: gam_toggle_get_state (). No idea what to do for mixer element "Input Source"!

** (gnome-alsamixer:4028): WARNING **: gam_toggle_set_state (). No idea what to do for mixer element "Input Source"!

and tried to unmute the front mic (see my gnomealsacapture.png:
tryed with sound recorder and ... after recording, the result is only a beep.
checked also pavucontrol: It seems that my mic was already selected see my pavucontrolinput.png

I am including another 2 .png:
1) pavucontrolnotdetectinginputsoundrecorder.png
2) pavucontroldetectingoutputsoundrecorder.png

When I record usign sound recorder, the seconds move and everything looks as it were recorded, but the output is a beep.

Please, can you give me more hints?

In your first screen, is it showing two sliders (L + R) for the mic? If so, try turning one down all the way. Mic should be mono.
