Sound recording on FreeBSD 5.1

[Orion Hodson]

Stefan

The below is great.  I have a feeling recording on the ich4 should work on 
4.8R, the upcoming 4.9R, and also on -CURRENT.  It's going to be a day or two 
before I confirm this (work, social life, etc), but it'll save you a 
potentially needless install.

Kind Regards
- Orion
