hi,

please, post the results of the following commands:

Code:

arecord -l

and

Code:

cat /etc/modprobe.d/alsa-base.conf

What is the model of your laptop?

good luck..

I'm using a HP pavilion Dv5 1102el: http://h10025.www1.hp.com/ewfrf/wc/d...roduct=3841102

I have to say that, in a previous Debian installation, the mic worked fine!

Btw, thanks for your help..

as root, edit your /etc/alsa-base.conf file with the text editor of your choice and add the following line

Code:

options snd-hda-intel model=hp-dv5

reboot and check your microphone...

Recently I had a similar problem and this solution worked for me...good luck!

FYI, you can find a complete guide to sound card related problems here.

Hi,
I had a battle getting my mcrophone to work,so I made a note of the settings. Change the card to suit.

Recording_settings.txt
Hope this helps.

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).

I guess that linux-backports-modules-alsa-generic package is specific for Ubuntu: may work for that, but might not be suited for Debian...

why "auto" when the model is known!??
