[b]UPDATE[/b]: as far as I am aware this version of skype is no longer able to logon. However, you might want to checkout the new "skype for linux" alpha - or the very similar web-skype beta, which work with alsa just fine.
Since I'm quite unhappy with how Skype 4.3.0.7 turned out, here's a link to skype version 4.2.0.11 for those who regret the update as well:
