How does one record audio?

If it use to work under Linux but no longer, are
sure you hardware is ok. Have you ever been able
to play any audio files?  Also, you have to use
mixer to adjust the input level and the recording
source. See man mixer.

Sounds like a hardware or configuration issue.

Also there is a Windows version of the Audacity
which I have used under Win2k it works nicely.

Oh, I guess that begs the question does the same
hardware setup work under windows?? If it does,
then expect it to be a configuration issue with
your sound setup [I have no idea if your sound chip
is support under Freebsd and I haven't used 5.1,
So someone else will have to answer that].

Have you searched the freebsd mail archive of questions,
stable, and current.

also does the device show up in your boot messages?

Sorry but in a rush,

David
