See, I thought I remembered that, but without arts or esd running, I was
able to play an mp3 on xmms while playing a cd on grip.  I heard both
songs coming through the speakers.  Well, I'm under the impression I had
neither running.  I seem to have gstreamer-artsd installed, but no other
artsd stuff.  I don't recall whether anything arts-related showed up in
the ps listing when I was running the above experiment.

That's a good point.

Ooh.  I didn't know that.  Does arts do this?

Since you seem to actually understand all this stuff ...

How does alsa fit into all of this?  If I have working sound drivers in
the kernel, should I care about alsa at all?
