set default sound card

[John Poelstra <poelstra redhat com>]

I am running F8 on x86_64 on a Dell box with an onboard Intel soundcard 
and speaker + a Soundblaster PCI card.

Whenever I run any apps that use pulseaudio the sound goes to the 
internal speaker and not the soundblaster.  Is there a sensible way to 
fix this from a GUI? I've seen lots of posts about monkeying with kernel 
modules and pulseaudio conf settings and wondering if there is simple way?

I've tried disabling the Intel soundcard in system-config-soundcard, but 
that doesn't do anything.
