Sorry guys, it seems I was a bit too hasty reporting this bug. Turns out the problem is actually in the mic itself. I don't have another mic handy so I plugged my headphones into the mic jack and was able to record some sound that way. It was a bit distorted, but that is most probably because I used headphones as opposed to a proper mic. I'll try to get me another mic and test it again soon. If there is still a problem, I'll reopen this bug. For now, I'm closing it.

If I crank up the mic volume all the way to 100% or over, I can hear some noise, but nothing more. I noticed that there are several bugs reported for this particular sound codec (Conexant CX20549 (Venice)), but none of them seems to be about the external mic. So I'm reporting this new bug. By the way, I'm pretty sure the microphone itself works fine, as I used it before without any problems.
