Guys, this problem seems to be common, but I can't find the solution.

The internal microphone in my Ubuntu 10.04 is not working, though it works pretty fine in Windows. My laptop is ThinkPad Edge 13.0 (Intel). I've tried a couple of solutions so far:

  1. Killing the pulseaudio
  2. Changing the values in alsamixer
  3. Changing the values in the default volume control

I tested recording with either standard Sound recorder in Ubuntu and also the following command: arecord -vv -fdat foo.wav

Everything fails.

What would you recommend me to do instead of buying the external microphone (it's not reallt good for me, because my current headphones are without the microphone and I'd better work with them.

Will be happy to get some help with it! Thanks

I'm posting here because I have the same problem on a Lenovo S10. –  tj111 Sep 16 '10 at 18:01

I had recently tried to resolve this same issue on my own laptop (Ubuntu 10.04 32-bit). It turned out I needed to select "Microphone 2" on the "Connector" dropdown under the "Input" tab in "Sound Preferences". My extrapolation for your situation (which might not work anyway) is to try each of the selections in that "Connector" dropdown and (hopefully) find one that works. It's muffled-sounding now, but better than nothing :-\

In any case, good luck!

Thing is that I don't even have my internal microphone as the option in those dropdown. After some of my recent manipulations of trying to fix this, the Input tab is now completely empty... ( –  lyuba Sep 20 '10 at 11:27

This is what I had to do to get the microphone to work on my girlfriends Acer Aspire One:

  1. Install pavucontrol (sudo apt-get install pavucontrol)
  2. Run pavucontrol
  3. Go to the "Input Devices" tab
  4. Click the icon to unlock the channels
  5. Set the right-front channel to silence.

I dunno if that will work for you or not, just something that has worked for me in the past.

It doesn't help, unfortunately.. ( –  lyuba Sep 17 '10 at 13:53
    
Didn't think it would (didn't work on my S10), but figured it was worth a shot. –  tj111 Sep 17 '10 at 14:12

The solution was in downgrading to the kernel 2.6.32-24-generic-pae

Okay, it seemed not to be a real solution, because with the internal microphone working fine the external speakers don't work. Sound keeps streaming though the internal ones. Anyone know the solution? –  lyuba Sep 16 '10 at 17:25
