UPDATE Pulseaudio update issue...

[Nathanael D. Noblet]

Ok so totally bizarre, I re-updated via yum... It caused rhythmbox to 
freeze as the connection to the server died. I killed and restarted it, 
and the track changes were now sound seamless, as is tab completion in 
gnome-terminal again...

I'm really not sure what the issue was, I've rebooted a few times today 
with noticing that an update had occurred, and then after the downgrade 
etc...

So whatever it was is no longer an issue... odd.
