>Description:
        Experienced this on my Lenovo T60 while running in X, in a
        vain attempt at capturing the audio being played:

        First issue:

          It appears that nearly whatever arguments you give to
          audiorecord, it will spew "Invalid argument".

        Second issue:

          If when you launch audiorecord, you already have an instance
          of the Linux-emulating (by necessity) Adobe flash player
          running inside firefox, audio from it will immediately halt
          when audiorecord is run (even though it itself says "Invalid
          argument").

        Third and most serious issue:

          Exiting firefox with the flash player, and restarting firefox,
          and then re-activating the audio output from the Adobe flash
          player will lead to a kernel panic.

>How-To-Repeat:
        See recipe above.
>Fix:
        Sorry, don't know.  I experienced this on my laptop, so could
        not get a stack trace. :(
