 Okay, I tried 'multi'.  Here's the error message:

  The other was "ttable" which may have
worked but I don't remember. Same
 procedure, just highlite the entry present and type the new one in. 
 And here's what I get with 'ttable':

 Okay, so this 'Interface' box, when you change it to something other
 than HW:0 or HW:1, I believe it's gonna try to get the configuration
 of that device from '.asoundrc'.  'ttable' is the same entry I got off
 the ALSA web site, but I never got it to function.  Do you still have
 your '.asoundrc' file?  It would probably be in your '/home/yourid'
 directory or in '/root' if you start 'qjackctl' as root.  I understand
 it could also be in '/etc/asound.conf'. 
Sadly I don't or this would be a fast conversation. I have had about 4
different setups since then and finally give up and bought a Delta
1010LT from Ebay! :) I'll look on one of my other machines...I may still
have it as a backup there.

 Any other alsa configuration gurus wanna chime in and help us out here?
