Well sure, Skype as of v4.3 requires pulseaudio.

That's for your onboard sound, what about kernel drivers for the USB device?

Also, forcing it to use ALSA will definitely not work with Skype as it
requires pulseaudio, as you've found out. You have to set up pulseaudio
to do all your audio processing or nothing will work.

I don't use Skype, but google even shows an entry on the gentoo wiki
detailing all these issues:

http://wiki.gentoo.org/wiki/Skype

It even was a workaround for non-pulseaudio users.

Google tells me Skype problems are pretty common, there are problems and
solutions on the web already.
