System: NetBSD 6.0 NetBSD 6.0 (JONSVATNET) #1: Mon Jul 1 
14:33:56 CEST 2013 
Architecture: i386
Machine: i386
        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

        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.

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