Hmm... I don't know what to do any more. Sorry.
As a last proposal, how about audacity-devel
(ports/audio/audacity-devel)?
AFAIK, there is a limitation for the stable version of Audacity
(ports/audio/audacity) to use USB microphones. See the URLs below.
USB-microphone in Open Sound System
http://audacityteam.org/wiki/index.php?title=USB_mic_on_Linux#USB-microphone_in_Open_Sound_System
[Portaudio] Prompting for all output and input devices separately
http://techweb.rfa.org/pipermail/portaudio/2006-February/005237.html
I don't know whether the limitation is applied to FreeBSD or not.
