Any progress with audio recorder?

I am a new SDL user. I started to get into it since I am interesting to
record internet radio (and video in the future). I saw that you published a
patch while back. Since I am a windows user I guess the patch will not be
applicable for me (I believe that I will need a driver that uses DirectX).
Have you or anyone you know, made any progress on this?
