Good to know. 

You can't use jack and have firefox doing stuff in the same soundcard
(there's a trick for that of course :-)

Desktop sounds, firefox and others use Pulse Audio for sound. So to try
that first stop jack. You have to see which card Pulse Audio is using.
In fc10 I _think_ that was pavucontrol (there might be a problem with
pulseaudio recognizing the 1010lt in fc10). See what that shows...
