I want to use the "audacity" port to record sound and play it back.
I don't have a mini-jack microphone, but I have a USB microphone.  The system tries to record from 
the motherboard sound card (which does not have a microphone attached).

If I run this command:
   sysctl hw.snd.default_unit=1
audacity will not start because my dsp1 does not have any out.


here is the output of /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <NVidia MCP51 High Definition Audio Controller> at memory 0xfe024000 irq 21 kld snd_hda 
[20071129_0050] [MPSAFE] (1p:1v/1r:1v channels duplex default)
pcm1: <USB Audio> at ? kld snd_uaudio [GIANT] (0p:0v/1r:1v channels)
         mode 1:(input) 1ch, 16/16bit, pcm, 8000,11025,22050,44100,48000Hz



I am using:
  FreeBSD 7.0-BETA4

For other with a similar situation:  this command:
  kldload snd_uaudio
get FreeBSD to recognize your Logitech USB microphone (from the Playstation).
