I'm using the Delta 44 on Mandrake 9.2, and it works perfectly.
Make sure you use envy24control right?
# urpmi envy24control
as the alsa mixer is incomplete for that card.

Yeah, used it for the first time last week.  Sound quality is SOOO much
better than a typical sound card.

I've been using audacity because it's simpler, but it's oss based, so
there are complications.  Can only get 2 channels working perfectly so
far.  Make sure to tell audacity that your project is in 48k bps, since
the card seems to play at that rate no matter what audacity says, and
you'll get screwed up wav/mp3 headers otherwise.

Ardour also works fine for me, and is alsa-enabled, but it's a lot more
complicated and crashy.
# urpmi ardour jackit-realtime
should install everything you need.  (reboot into the multimedia kernel
I'd also suggest mounting /tmp as tmpfs (see the jackit website).

You've chosen an excellent card and an excellent distro!  :-)
Try tkeca, snd, sweep, dap, ecawave, freqtweak, glame, mhwaveedit,
rezound, SpiralLoops, terminatorX, wavesurfer... all good stuff.  You
should be able to install any of them with urpmi.  If not, just set up a
'contrib' repository first.

I packaged most of them myself.  Let me know if you have any problems. 
Trying to get things polished for Mandrake 10, due in February!
