mic not working

I'm running ubuntu version 7.04 (beta version)

are you sure that the 'capture' is at full setting in your sound settings.

System > Prefs > Sound

Well, when I open the address I get:

sound capture: ALSA- Advanced Linux Sound Architecture

When I hit the test button I get the test window, but no activity is detected (the test bar doesn't move). The only option left is Accept (OK).

PD: in the MIxer I have HDA (Intel ALSA Mixer) with all the options in (bold)

Roberto

Please, execute

lspci | grep -i audio

to be able to know more exactly your sound card device model. With this info we will be able to get better answers :)

Sounds like you must inform some strict parameter on alsa to be able to use the microphone

Example:

My machine is a Dell Inspiron 630m with

Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

and I was unable to use the mic. After research, adding

options snd-hda-intel model=ref in /etc/modprobe.d/alsa-base solved the problem

Knowing about your hardware will help ;)

The output of: lspci | grep -i audio

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

Tried with the instruction you gave me and didn't get it to work.

I've got this:

alsa-base: script-in-etc-init.d-not-registered-via-update-rc.d
alsa-base: syntax-error-in-debian-changelog

in the alsa-base file located in the /usr/share/lintian/overrides

any clue??

This is the output of the /etc/modprobe.d/alsa-base file:

Try to add this line at the end of the file /etc/modprobe.d/alsa-base

options snd-hda-intel position_fix=1 model=3stack ( you can try this line without the position_fix=1, test both configs )

Reboot and try to use the mic

May be try this one

options snd-hda-intel model=ref position_fix=0

fits exactly with your model card / problem

Hi, well I'm new in this, but I have the same error as Roberto, but when I try to save the alsa-base file it doesn't allow me. What should I do?

Hello again, ok I edit it

The microphone is working with Skype but itś not workin with the Sound Recorder, is there something else I could do? Thank you

Well, I have the same problem...
Mic works with skype, but it doesn't work with other applications...

I did the upgrade from alsa to the last version... (1.0.14rc3 which is in beta) and then choose OSS instead of alsa in every option of the preferences -> sound menu.
The suggestion from David Ballester of adding:

options snd-hda-intel model=ref position_fix=0

was made also...

The sound works perfect, but the mic keeps having this strange behavior.

I have tried for more time than I care to admit to get my external mic to work under Ubuntu and I have failed. This seems like such an easy fix that there must be somwone who can help.

Pleas please help!

I had to update my Alsa drivers; something was wrong in Feisty - either with the Alsa drivers or the way Feisty handled them. I put instructions here: http://ubuntuforums.org/showthread.php?p=2798055#post2798055

Hope that's some use to you.

Open up the Synaptic Package Manager and install ubuntustudio-audio and ubuntustudio-audio plaugins.

Next, open up QAMix, go to Capture TAB and set it to MIC.

Didn't work for me... A little more detail might help though. How do you recommend testing the recording of the mic? I was using command line "arecord".
I should also mention that I am trying this on a laptop mic input. I have tried this on many different makes and models with no success.
