If pulse audio is running, Skype will not permit you to use alsa directly (because to do so would break any application that tries to use pulse). You can't even kill pulse audio because it will restart itself. I don't think it's possible to remove pulse audio without removing a lot of other stuff either - however you might be able to find something on google that tells you how to disable pulse audio so it doesn't start. But pulse audio is generally a good thing so that would be a last resort. If you've got it working I'd just leave it.
