Ubuntu annoying problem fixed

So I have had an issue with my machine for a while... could not get my microphone to work in Skype, or anywhere else for that matter.

I tried playing with settings, to no avail; it just wouldn't do it.

I finally got it solved, so I'm going to post the solution here. It's easy: go to applications, and under "sound & video" launch "sound recorder". Then change the "record from input" setting to "capture" instead of "digital". Voila.
