Mic is not recognized using card [HDA NVidia] VT1708S Analog in ubuntu 10.04 or 8.04
 

Thnk you for your time in advance:
what I did, I followed this link 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:

# 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

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.p...nsaver+working
the output necessary to check issues. here it is:

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

I am including more information as it was recommended to me in an automatic mail
It seems I have already installed gnome-alsamixer.
I tried the following
in terminal typed gnome-alsamixer: see .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:
trying with sound recorder and ... nothing
checked also pavucontrol: see my .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. If I kill pulseaudio, then I cannot record or play using soundrecorder.

If I record using audacity, the second move and everything looks as it were recorded, but the ouput is silence.

Please, can you give me more hints?

i also had trouble getting my mic to work with this chipset. Turned out I had to "mute" the "smart 5.1" option in the mixer :rolleyes:

Dear Matti3,
I had surfed the net and others solve the question the same way than you. However I cannot find the "smart 5.1" in the alsamixer. I am sending you a .png of my alsamixer, can you check it and tell m how to "mute" it?
I guess that there is something to do in a config file, would you please specify step by step what to do?
Than you in advance

hi, sorry for the late response. Just use the arrowkeys (left/right) to scroll through the different items. The Smart 5.1 control is located at the far right
Attachment 5383.

Dear Matti3,
thank you for your response, unfortunately, there is no SMART 5.1 in my CHIP; you have a NCP77/78 HDMI and I have a VT1708S. if you see my .png, the last element when you scrolled all the way to the right is the Input Source: I have 3 options: Line, Stereo Mixer and Mic, I have selected this last one.
Can you still help me?

You may have better results if you change from Alsa to Jack.

Dear Stress Jukie,
thank you for your advice, I will try, can you tell me if it is proved to work with my chip: VT1708S?

Dear linux user,
I finaly found the answer in http://ubuntuforums.org/showthread.php?t=1504904
the 'front mic' is still not working, but the back mic, also called only 'mic' is working.
so the mic is recognized using this card hda-nvidia-vt1708s in-ubuntu-10-04 and this post is solved.
the solution is:
1) use your 'mic' and not your 'front mic'
2) use your controls to get the correct levels, you can see more in the link of ubuntuforums above.
3) I will answer any user with the same problem in order to get the capture working.

Thank you for posting the answer. :)

Dear Junkie,
I am not sure if you want me to clarify the answer, I will:
the problem was solved the following way:
in alsamixer > playback > all "mics" has to be "muted"> use "M"
in Sytem>Pereferences>Sound>imput> clik to the "shield" *this will free the slides" scrolled one of them all the way to zero and you will have a "mic" capture with "mono"

If anybody need a more specific explanation. I will be glad to help.
