should be one.

What do you see in /proc/asound? Try:
  cat /proc/asound/cards
  cat /proc/asound/devices

It would be interesting to find our why the device is busy. It could be
that somehow you are getting a kernel oops (when something inside the
kernel itself find internal inconsistencies, or segfaults - very bad
:-). Check the contents of /var/log/messages to see if you see something
that has the work "Oops" in it, or something that looks like a stack
