getting echoaudio soundcard to work - now it won't record

Hi again. I sudo nano'd as instructed.
Tried "Sound" but under "audio conferencing" my soundcapture says 
IndigoIO (Not connected).
The error message reads
gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink 
profile=chat: Resource busy or not available.
I imagine there is something I am missing.

BTW --
I also want to eventually use a Windows sound application through WINE. 
I want to use Dragon NaturallySpeaking 8. It runs pretty well using ALSA 
(as good as it does on Windows XP)
but I want to make it run better. Am counting on Indigoio + less latency 
to give it a significant accuracy boost over my standard configuration.
But right now, I would be happy to be able to record in 
gnome-sound-recorder, which is what I'm testing with.
I'll go for sub-5 latency as soon as I straighten this out.

  The following is the output from etc/modprobe.d/alsa-base, with the
  changes I made to get the indigo io to run.
  Just adding  options snd-indigoio index=0 near the bottom works but
  did not survive re-booting.
  The indigoio now runs great in the output mode, but I can't get it to
  record, and think I may have another error below.
  Also, the little audio icon in the upper right is on "mute" no matter
  what I do.

  Hi Susan, the edit did not survive the reboot?  Make sure you edit /
  etc/modprobe.d/alsa-base  as root.  For example:

  $sudo nano /etc/modprobe.d/alsa-base

  Also, you don't need to comment out every line in the options
  section, I would leave them enabled.  For example if there is an
  integrated soundcard on your system, it might need to be 'demoted',
  if not entirely disabled in the bios.  But I am awfully fond of my X-
  session usb controller so for me, I compile Alsa with 'usb-audio' in
  addition to layla20 and in the options section layla gets 0 and usb-
  audio gets 1.  As you might notice, this would require changing its
  value from -2 to 1 in the file since someone decided this might cause
  initial complications.

  After installing ALSA the default alsamixer is typically muted, but
  if you get sound thats fine.

  Regarding the sound control in the 'studio desktop, try assigning
  your device as the default soundcard in the Sound preferences.  I
  ignored it for quite some time without any ill affect.  At some point
  I updated another sound library and it started working, so pretty
  messy on the maintainers part.  Anything related to the echo device I
  use echomixer for - alsa mixer can go play tennis for all I care.
  You might make a keyboard shortcut for the echomixer, or add it to
  your desktop panel bar.  I like using the function keys for terminal,
  echomixer, firefox etc.

  For problems recording, take a peek at the echomixer VU meters to see
  input activity and levels.  I might ask what app you use to record as
  well.  If you have not done so, you might try starting qjackctl and
  creating a profile for your device.  Most options can be left
  disabled, but leave rt checked.  Try out 256 frames, 2 periods to see
  if that works.  My guess is that 128 frames, 2 periods with rt
  checked should work in general.  Once qjackctl is running, open up
  ardour which needs jack to be running first.

  Ubuntu Studio Fiesty installs with the 'low latency' kernel.  If you
  feel ambitious and want sub 5 ms latency you can install the
  'realtime' kernel patches referenced in the Multimedia Production
  forum for Ubuntu.  This requires more tweaking, but you can
  significantly increase the performance of the echo device this way,
  though it might be fine for your uses now.

  I have been using a windows application called Reaper which runs well
  in Ubuntu Studio with the wineasio driver and wine.  Its another
  project, but it lets me run and record windows vst instruments I have
  done sound design for.

  So, some partial success!  Almost there...
