Hi Doug.

What is the Make/Model of your machine, and PC, or Laptop?

Which Ubuntu, or Kubuntu version? Ok I see that's Intrepid on your subject 

If Ubuntu, pulseaudio may be the problem, and it may worth removing 
pulseaudio, then seeing if the mike now works. To remove pulseaudio use the 
command below. You can always reinstall it with apt-get install pulseaudio.

sudo apt-get remove pulseaudio

It may also be worth looking at alsamixer on Gnomes terminal. If you are using 
Ubuntu, typing alsamixer in the terminal will just bring up the control for 
pulseaudio, so open alsamixer as below, and you will see all the mixer 
settings for your soundcard.

alsamixer -D hw:0

This will show playback controls. The F4 function key will show capture 
controls, and there is some microphone stuff there. The F3 key will take you 
back to playback controls.

I've no experience with Skype, or microphones for that matter, but if the 
above hasn't resolved your problem, it's not the alsa-utils package, but the 
alsa-driver tarball you should have downloaded. Get the latest snapshot from 
the link below. Don't get the unstable one, just the one  named 
alsa-driver-snapshot, which will be the latest. Either the .bz2, or the .gz 
one will do.


Just to keep everything organised first create a new folder in your /home/user 
directory named Alsa-drivers, then download the latest alsadriver snapshot, 
and put it in this directory.

Having done that, open a terminal, and type the following.
cd Alsa-drivers
Now type the following, and this depends on whether you have downloaded the 
tar.gz, or the tar.bz2 version of the snapshot.

For the .bz2 version.
tar xjvf alsa-driver-snapshot.tar.bz2

For the .gz version.
tar xzvf alsa-driver-snapshot.tar.gz

So far so good? You should now have a new directory in your Alsa-drivers 
directory named alsa-driver.

Before going any further, install the package below, as I believe it's 
necessary. Don't do this on the terminal you have open for working with the 
alsa-driver, but open a second terminal, then on the new terminal type the 
sudo apt-get install build-essential

That done, exit the 2nd terminal, and now we can get back to compiling the 
alsa-driver snapshot.

Type the following on the terminal that is still open.
cd alsa-driver

Do check that the newly created directory is named alsa-driver, and if 
different, change the cd command to the actual directory name.

Now type the following commands as user.

That runs for a while, and then should complete without complaining.

Now type the following.

Make should run to completion, without complaining, but takes some time.

If it complains, post back. If it doesn't complain type the following.

sudo make install

That should upgrade the alsa driver to the latest snapshot version.

To check this out, and now see if you have the latest alsa-driver version 
installed, reboot, then run, cat /proc/asound/version, which should show alsa 
driver version 1.0.19.

If this has gone OK, you may still have to mess with mike settings in 
alsamixer to get Skype doing it's stuff.

Apologies if my help falls short, and doen't help to resolve your problem.
