I went and tried some things.
Importing it: The "Play" (audition) button caused a segmentation fault.
Embedding it: I did try the "split" button, and I did get 4 "tracks" out of
that in the clip window. But all four of them showed up as silent - ie flat
line in waveform display, no sound when played.
Just to be certain, I used "aplay" on my source .wav and it plays back fine.
I was also able to audition clips in a different session that had all been
recorded in Ardour, and that works fine (I also double-checked the audition
output in the Options window).
The .wav files I'm trying to import were recorded with "arecord" with the
arecord -f S24_LE -c 4 -r 44100 foo.wav
I'm trying to match what I was doing with Jackd:
jackd -R -d alsa -r 44100
(should be 24 bits from the Delta-44, right?)
Hmmm... is there some issue with 24 vs 32 bits in the .wav file? I think
I've been able to import 16-bit .wav files without having to do anything
special in Ardour.

And you'll visualize not taking any chances
But meet them halfway with love, peace, and persuasion
And expect them to rise to the occasion
