Is there a simple "how to" guide for getting sound to work with FreeBSD?
The handbook seems to concentrate on playing MP3 files and ripping CDs.
I suppose I'd better start from the beginning...
FreeBSD 4.10-BETA, Acer MX3-W Pro m/board.

The sound works just fine when playing CDs or MP3 files, but how does one
record? Not knowing any better, I plugged the audio source into the
mic input, and just did a "cat /dev/audio".
What I seemed to end up with was a raw .AU file, which few programs can
recognise (I tried SoX and Audacity). If I copy it back to /dev/audio, I
hear the original, but I have a feeling that I'm missing something.
So, is there a "better" way? I'd be looking to produce MP3 or WAV.
