PulseAudio is the new sound server that's installed and enabled by
default for Fedora 8. It handles sound input from esound/arts/ALSA/etc
and does fancy mixing and transporting and generally makes sound support
totally awesome. You can get more info about it here:
http://fedoraproject.org/wiki/Releases/FeaturePulseaudio

Since it's a replacement for esound/arts, it's started when you log in
to GNOME/KDE, just like those programs were.

Here's the problem: Skype apparently still doesn't know how to use ALSA
properly. Since it's a closed-source app there's not a lot we can do
about that. There appears to be a workaround mentioned here:
http://developer.novell.com/wiki/index.php/Feisty/HOWTO:_PulseAudio#Running_Skype
Basically, try running: "padsp skype" and PulseAudio will emulate the
OSS interface to make skype happy.

Hope that helps.
