Internal microphone not working for HDA Intel ALC269

[ferrouille]

Hi all,
I just installed ubuntu 10.10 about 10 days ago, an experience that has been both amazing because its really hard for me to go back to windows already, and frustrating because I'm having a little issue: my internal microphone is not working.

here is some relevant info:
I had alsa 1.0.23 and decided to upgrade thinking it would solve my problems so I ran the script to install 1.0.24, and for a day or two I lost my sound, without getting back my mic, and just like that the sound came back.

I read a lot of posts out there, and ,ade sure I unmuted my mic in alsa soundmixer and pulseaudio.

here is some additional info:
http://www.alsa-project.org/db/?f=de...db476094f89e0e

I ran this:
sudo aplay -l
result:
card 0: Intel [HDA Intel], device 0: ALC269VB Analog [ALC269VB Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0

that is kind of weird because I'm positive that this command would return ALC259 under alsa 1.0.23...

also I ran: ls /etc/modprobe.d
and the result is:
alsa-base.conf blacklist-framebuffer.conf
alsa-base.save blacklist-modem.conf
alsa-base.save.1 blacklist-oss.conf
blacklist-ath_pci.conf blacklist-watchdog.conf
blacklist.conf intel-5300-iwlagn-disable11n.conf
blacklist-firewire.conf

finally here is the alsa-base.conf content:

your experienced thoughts are much appreciated

I want you to edit alsa-base.conf to remove this line:

options snd-hda-intel model=laptop-amic position_fix=0

To open:

gksu gedit /etc/modprobe.d/alsa-base.conf

Save it then delete these items:

sudo rm -r alsa-base.save alsa-base.save.1

Now reboot.

With aplay sudo is not needed and best run without it.

thanks lidex - I did all the above without seeing any success.
in fact I am now without sound or microphone.

any thoughts as to what are my other options?

Rerun the info script please.

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

Choose the upload option and provide a link for the output.

Play around with these models in alsa-base.conf, one at a time please:

auto
lifebook
basic		
quanta	
eeepc-p703	
eeepc-p901	
fujitsu

In this format:

options snd-hda-intel model=

Reload alsa after each change is saved:

sudo alsa force-reload

Lidex,
the first attempt with AUTO as the model was the good one - thanks so much for the help!!!
party time on my ubuntu now
