Why not use the xmms disk writer?

But dmix won't help with recording, it's purely a playback mixer. Even
dshare won't help here. However I had some success using the "tee" or
even better, the "file" plugin.
Use something like this:
pcm.recorder
{
type file
slave.pcm "default"
file "/tmp/recorder.raw"
}
It will record a "raw" soundfile, which can be opened with Snd and I
think, Audacity afterwards with some experimentations on channel
count, sample rate and byte format.
This does indeed work with realplay if you set up aoss accordingly
(see alsa.opensrc.org for more hints on that). I have tested this. For
ripping mp3 and ogg streams it's better to just use "wget". ;)
And then mplayer can read many stream formats including wma and write
them to disk.
Ciao
