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. --- Watanabe Kazuhiro (CQG00620@nifty.ne.jp)
