Microphone problem in Ubuntu 11.10

The settings for the microphone can be accessed by clicking on the sound icon at the top right bar, which looks like a speaker with the sound waves coming out of it.

If you click on that then you can see the option to open your sound settings. Do this and go to input, which is microphone. You might have a couple options like front mic or rear mic, and you might need to try out those options.

A lot of this has to do with your sound card which is usually on board your motherboard. Can you tell me what kind of motherboard you have?

Oh, and sometimes the problem lies within Skype, try to open the options in skype and see whether you have options for your mic.


In terminal write alsamixer and you will get a sound manager. Once in, press F4 to access capture settings. If any of the "Capture"-modules have a couple of lines underneath -------- , try marking the module with the arrow keys, and pressing Spacebar .

You will see some red text, which indicates, that the module is recording.

Maybe this will work.


Try reducing the Mic Boost on alsamixer to 0, doing so lowered the background noise so my voice was audible. It's not perfect but it seem usable on GoogleTalk/Skype, I tested it on the sound recorder.

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).
