What happened? What did you expect to happen?

When I click the record button, it acts like it's recording, then I click
stop and I get the following error:

Traceback (most recent call last):
  File "ankiqt\ui\facteditor.pyc", line 912, in onRecSound
  File "ankiqt\ui\sound.pyc", line 37, in getAudio
  File "anki\sound.pyc", line 256, in postprocess
Exception: 
Error processing audio.

If you're on Linux and don't have sox 14.1+, you
need to disable normalization. See the wiki.

Command was:
sox tmp.wav tmp2.wav noisered C:\Documents and Settings\[my
name]\Application Data\.anki\noise.profile 0.1

I'm using a SB Audigy 2.  I recorded the noise profile.  I tried with
"microphone" as the record choice (same error).  Then I tried with "What
you hear" and same error.  Then I tried with my bluetooth headset and same
error.  All other record features in all other programs are functional
