Some basics are there - basically you need a gstreamer pipe with dsppcmsrc at one end and a udp (or tcp) sink at the end with encoding in the middle.

which has the details (names of the sources and sinks) and links to gstreamer doucmentation.

For XP, there are some virtual soundcards or audio interceptors which can save, record, or stream. I have a macbook so use stuff from http://rogueamoeba.com/ but have found XP (and linux) equivalents.
