[orca-list] Application-specific sound card assignment in Natty

[Alex Snow <lists h14me net>]

Hi All,
Been googling for the answer to this for a while, but so far nothing has 
worked...I'd like to assign certain applications to my second sound card 
(music, audio from flash in firefox, etc).  I installed pavucontrol per 
several results on Google, but I can't seem to make it assign different 
apps to a sound card.  I see the entry for speech-dispatcher, but 
there's no button next to the label like a previous post on this list 
said there would be.  The second sound card is a generic USB audio 
device, that's detected by alsa, I just can't seem to get anything 
working with pulseaudio in the desktop.
Any help would be greatly apreciated...
