System: NetBSD jonsvatnet.uninett.no 6.0 NetBSD 6.0 (JONSVATNET) #1: Mon Jul 1 14:33:56 CEST 2013 he@jonsvatnet.uninett.no:/usr/obj/sys/arch/i386/compile/JONSVATNET i386
Architecture: i386
Machine: i386
>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. :(

 Did you get the panic message?

 Sadly, no, since it was on a laptop with X11 running.

 I'll try to see if I can reproduce it on another system.
