Oops, I'm really sorry: I added the wrong file to the archive. If it's
any use, the file I actually intended to upload (still 32-bit floats
recorded through Jack, I'm afraid) is here:
http://www.starlingaudio.co.uk/misc/received.wav.tar.bz2
Floating-point samples (as used by e.g. Jack)
don't show what bits the
device sent; please use arecord, like this:
arecord -D hw:UA1000 -f S32 -r 44100 -c 10 something.wav
Here's one seconds worth of 12 channels recorded with arecord, with
440Hz of (approximately) sine wave in channels 1, 2, 3 & 4, and silence
in the rest:

(There are 12 capture channels on the UA-1000: 1-8 are analogue inputs,
9-10 are the SP-DIF, and 11-12 are a mix of the output signals.)
I hope this is more helpful than my previous try.
Cheers,
Colin.
