I want to run a sound recorder like audacity to record
what is coming thru my soundcard when playing
streaming audio thru xmms.
However audacity can't open the audio port /dev/dsp
when streaming audio is playing. This is on knoppix
3.4 using the OSS driver.
Would using ALSA make this possible?

yes. you would need to set up the dmix plugin in .asoundrc.
Another alternative is using jackd enabled applications. For instance,
you can play the stream with alsaplayer and record with ecasound. Or
even play and record with the same ecasound ... I think, since ecasound
is just calling ogg123 or mpg123 and communicating over pipes with them,
I think it can pass the stream URL to them and take their output as
input, then write out to a file (via lame or oggenc if that's what you
want).
I don't use xmms so I don't know if it has a jack plugin.
If your soundcard and its particular oss driver supports it you may be
able to open the oss device twice by referencing different devices in
/dev/, i.e. /dev/dsp0 and /dev/dsp1. But, I have no direct experience
with that since I have never used oss drivers.

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.

Why not use the xmms disk writer?

Well, I once recommended to use "dshare" for grabbing streams, and I
did suggest this in front of a large audience (larger then this list).
Dshare also doesn't work of course. Don't tell anyone, I hope everyone
forgot about my suggestion by now. ;)

as a quick and dirty solution, xmms has a disk-writer output plugin.

Another option.
The mp3 and ogg vorbis plugins have an option to save the stream to a
file. That way you can hear the stream while recording.
