Hotplug audio devices

[Casey Dahlin <cjdahlin ncsu edu>]

I own a USB headset, and I've found using it on Fedora to be a tad more 
hassle than it should. Whenever I plug it in, I have to switch the 
default soundcard in system-config-soundcard and then close any program 
using audio so that it will change cards.

How can we improve this?
